About this page

Weather forecast sources in the Baltic; based largely on the experience of others coupled with my own native wit.. I have no experience in these waters. I hope that it will be updated from time to time - but this can only be done if there is input from those who sail in the area.

Introduction and acknowledgements

Having no personal direct experience in the area, I had a useful start from James Latchford and Graham Cattell supplemented by input from other CA members (notably, Roger Saunders) and other sources - mainly ALRS Vol 3(1) and the Internet. Information on Poland was kindly provided by Marcin Palacz.

The expertise of James and Graham (and other CA members) is available through the Baltic Section of the Cruising Association membership of which is strongly recommended to anyone cruising the area. In particular, James has produced a very useful glossary of terms and has given examples with interpretation of forecasts that you will hear on the radio. It is also worthwhile looking at texts available on the Internet in order to see the format, terms used and, often important, the place names used.

In the following, I have largely avoided reference to Public Radio Service broadcasts. Partly this is because of the schedules which are likely to change. James Latchford does make the point that there is a fair degree of commonality between German, Danish and Swedish. Therefore, it can be worth while using these broadcasts from these countries and, also, those Finnish stations that broadcast in Swedish. Finnish as a language is quite incomprehensible to most other nationalities. The CA Baltic Group makes the latest known information available to members.

James makes the following recommendation regarding equipment for receiving forecasts -

  • Essential: - VHF R/T, and transistor radio with normal LW and MW bands
  • Very advisable: - German, Danish, Swedish dictionaries, and tape recorder
  • Very useful: - simple SSB transistor receiver covering wider bands and with digital (memory) tuning.

To these, I would add a NAVTEX receiver - as being in the essential category for sailing near coasts in many countries and particularly so around Europe.

A list of useful VHF channels is in Appendix 1. Names of Baltic Sea areas in four languages are in Appendix 2. Swedish coastal area names are in Appendix 3.

NOTE 1 Forecast and actual wind speeds in the area are quite often given in metres/second. A sufficiently accurate conversion to knots is to multiply by 2 ie 10 m/s = 20 kn or, for a good approximation, divide m/s by 2 to get the Beaufort force.

NOTE 2 As ever, translations from one language to another may not always be accurate when done under pressure of time and I have been told that some Swedish translations are incorrect. In my experience, it is always worthwhile learning enough of the weather vocabulary to listen to the originals.

Marine Radio Services

Stockholm Radio operates over 50 VHF stations from the Norwegian border in Skagerrak, up to the Finnish border in the northern Bay of Bothnia - including the sea around the island of Gotland as well as the lakes Vänern, Vättern, Mälaren and Hjälmaren. These stations are remotely controlled from STOCKHOLMRADIO which is the call sign for all. Locations of the stations are in the pilots and on the Stockholm Radio VHF page which also has schedules.

Swedish VHF forecasts are broadcast four times a day. They are available over a very wide area and are pretty reliable. These forecasts have been heard as far west as Kristiansand at the southern tip of Norway and in parts of the Danish Archipelago. Note that the timings and formats of the forecasts are liable to change.

Up to date times and VHF channels are given each year in the free publication Kustregistret (KR) which is available at Swedish marinas. Note that the timings in KR are in a mixture of UTC and local time and can readily be misunderstood.

Forecasts are usually about three minutes late but sometimes a little later due to operational problems. They are usually preceded by the Morse letters SDJ repeated for a minute or so. If you have difficulties getting a good signal on the expected channel it is worth using the scan function on your VHF to see if some other channel gives better reception.

Coast Radio announcers differ in their fluency, confidence and flow. In Swedish quite distinct dialect variations can be distinguished. (e.g. morning can be spoken as formiddan, formiddag or formiddagen)

A similar service is provided by Turku through its remote stations. Otherwise there are a variety of VHF and MF (mainly SSB) stations as in the table below which shows the (known to me) published schedules and frequencies.

German North Sea Areas

Radio Fax

Offenbach and Northwood (are the only two fax broadcasts available. Northwood broadcasts forecast charts including wind vector format twice a day. The winds shown are usually only those exceeding 25 kn. These are for two days to five days ahead. The wind vectors show the wind direction with feathers" giving speed. One long feather = 10 kn, one short feather = 5 kn. SW 20 kn and N 25 kn would be as shown here.

The Deutscher Wetterdienst has accepted the responsibility to provide RadioFax charts for the area under the GMDSS. Full schedules are available on the Internet, see my GMDSS page for details.

Radio Teleprinter

Radio Teleprinter broadcasts from Hamburg (Pinnenburg) are also part of the DWD contribution to the GMDSS. There are 5 day forecasts (wind and sea state at 12 hour intervals). Other Offenbach (DWD) outputs are two day forecasts (wind, weather and sea state at 6 hourly intervals), sea area and coastal forecasts for the next 24 hours and actual reports from a small selection of stations..

The 2 and 6 day forecasts are direct output from the German numerical weather prediction model. Programme 1 (mainly in English) is on 4583, 7646 (both at 1 kW power) and 10100.8 kHz (10 kW power). Programme 2 is mainly in German but, with a little effort is readily understandable. Frequencies are 11039 and 14467.3 kHz (both at 1 kW power).

Most forecasts are repeated on one or other of the programmes so that reception should be possible even if you have to have more than one go. For those with no German, Tief = Low, Hoch = High. The first two letters of the days of the week from Sunday on are SO, MO, DI, MI, DO, FR, SA. Germans run words together so that Suedostziehend = moving south - eastwards.

Reception of both Radio Fax and Teleprinter can be very dependent upon time of day and location. Full Schedules are available on the Internet, see my GMDSS page for details. Go to the Appendix of the Western Med Forecasts page for an example of a 5 day Med forecast (the format for the Baltic and North Sea forecasts will be similar. There are also some hints in dealing with corrupt texts.

National and Local Radio

Sveriges Radio P1 broadcasts in Swedish at the following times:

0555 Sun
Including wind information, wave heights and water levels
0655 Sat Five day forecast
0755 Sat Sun
Does not cover the North Sea
1250 Sat Sun
Does not cover the North Sea. At 12:55 on weekdays
1555 Sun
Including wind information, two day forecast
2150 Sat Sun
Including wind information, two day forecast and seven day forecast for land weather

All P1 broadcasts can be heard later on the Internet at http://www.sr.se/vader/. Brief land weather reports are provided by “Ekot” news broadcasts on most full hours and at 16:45 on Swedish Radio channels P1, P3 and P4 (in Swedish only). Land weather reports and in the summer often coastal weather reports as well are provided on the half-hourly news broadcasts on Swedish Radio’s local channels.

Radio Stockholm broadcast an archipelago weather forecast of their own in connection with the news.

NOTE These times may be subject to change in which case reference should be made to the current version of "Väderkortet" - a small card issued by Sjöfartsverket and obtainable from chandlers and guest harbours free of charge. The FM frequencies for particular areas are obtainable from the Svensk Kusthandbok.

For the area names see Appendix 3.

Advice from members of the CA Baltic Section is that, in the S and SW Baltic the meteorological services provided by German public radio services are so good that they are regarded as essential listening.

They give a (sometimes too) detailed synopsis followed by shipping forecasts for the appropriate North Sea and Baltic sea areas, all at easy dictation speed. They are in German but, even with no previous knowledge of German, and after a little effort and experience, they are quite easy to understand. They are particularly useful when in Danish waters when out of range of Swedish coastal stations.

There are, of course, many other local and national radio forecasts but these are very variable and can change at short notice. CA members should seek advice from the Baltic Section.


Many forecasts are now available on the Internet. These include charts from the UK Met Office and other centres, some of the RTTY services from Offenbach, many GMDSS forecasts. This is fine if you are ashore with WiFi or land line broadband access.

It is a different matter if afloat and trying to use a cell phone. GPRS, effectively 2.5G, or 3G are now widely available but costs can quickly mount up. It pays to ensure that you can use the cell phone economically.If you keep to text information then downloading direct to a cell phone, PDA, hand-held or laptop computer can be reasonably cheap.

At no charge apartt from communications, use links on my Forecast Texts page. If you find pages that are too heavy with graphics and advertisements, then use the text retrieval services mentioened below.

The Danish Met Service site has clickable chartlinks to the HIRLAM meso-scale forecast model. For those who like to see actual reports, there are several links at my Actuals page.

For planning purposes, a very useful service is available from the DWD for the Nordsee and Ostsee. These are winds a relatively small number of grid points taken from the DWD numerical weather prediction model.

Forecasts by email and GRIB files

Text retrieval services give low cost access to texts off web pages. This is a useful facility when the texts are embedded in a page with logos and other gimmicks that are costly to download over a cell phone.

INMARSAT - C and Mini M. can also be used for sending and receiving email as can satellite telephone and, when near the coast, GSM and GPRS phones For some general notes and links on these topics see the page on Internet connection while cruising. Another page has advice on setting up your cell phone to laptop connection.

Météo France NAVIMAIL, Movingweather, and Météo Consult all provide services via email on repayment. The same data can be obtained using FREE GRIB coded services.

These are easy to use and one email can "order" forecasts for as long as you wish. For an area the size of the Baltic, 8 "charts" covering a five day period (say, 12, 24, 36, 48, 60, 72, 96 and 120 hours ahead will be less than 10 kb.

Probably the easiest way to get GRIB file forecasts is to use zyGrib. This is another free service and very useful for one-off requests. Alternatively, use email via SailDocs. This is one of the free email services. Viewer software is also free from various sources. An example of the output using the Saildocs Viewfax is shown here.

Care is needed with GRIB services see pages on Use of GRIBs and a general page on NWP.

% center width="500" height="500" align="middle"%

Web page presentations of vector winds forecast using GRIB can be obtained from a variety of sources. www.passageweather.com gives GRIB output for the approaches to the Baltic. www.windfinder.com gives choices of the Baltic States, Denmark, Estonia, Latvia, Lithuania, North Germany, Norway, Poland, Scandinavia and Sweden, Select Continent, Country then choose "Animate" and use "Stop" and "Next" to step on one chart at a time. Specific areas can be bookmarked. I find the charts a little fussy.

A Polish university provides forecasts using the UK Computer model (UM) at the very fine grid length of 4 km for 48 hours and from the US COAMPS . There are meteograms and some rather fussy charts. The Danish Met service also produces a very useful page with a wide range of forecasts. These include Wind speed and direction for a selection of areas of the Southern and Western Baltic and parts of the North Sea. These are from the HIRLAM model; this is a co-operative project involving Scandinavian countries, Ireland Spain and Iceland to provide short period detailed forecasts.

HAM Radio and HF email

I have had a demo of HAM radio from Ross a liveaboard, circumnavigating Australian on Gemini, a 45 footer with (by my standards) space and power supplies galore. Those with the time, inclination, ability etc plus the necessary facilities can access much of the above information at no charge - apart from their licence fee etc - via Amateur (HAM) radio using Winlink which holds a Catalog of "standard" items that users find useful or have been recommended.

As I understand it, the Winlink system works as follows. When someone asks for a Catalog item using email over Amateur HF radio, the request goes into a network participating stations.. If a station has caching turned on for a substantial number, say, 100, then the most popular 100 requested items are cached and the response is immediate. If the response is not cached in the local computer memory, then a program goes out to the Internet and picks it up. Many weather products have duplicate URLs

in case one is down or not up to date. If possible, Winlink has at least one backup URL for each product listed. GRIB products can be obtained via Winlink or by directing an email over HF to either Saildocs-Free-Grib-Files For more information than I have go, to the Winlink or SailMail home pages.

Until such time as satellite telephone services becomes affordable, this seems to be a viable solution to accessing Internet products when at sea and out of GSM telephone contact. Even with GSM telephone, and current charges, HF radio offers a cost effective alternative to Internet access and email. However, due to propagation and reception problems it may not be available 100% of the time.

Also on HF you may find it useful to listen in to various Cruiser Nets.

Marina Offices

Many marinas and harbour offices display forecasts from varying sources. These may be the National Met Service, private Met firms, the Internet etc. The quality may, therefore be somewhat uneven and forecasts from the different sources may not tally. As ever, the sailor is faced with conflicting advice and has to make a judgement based on experience. Because of my background I generally prefer the National Met Service versions.

WARNING - a general warning for all forecasts, but particularly those posted in marinas and elsewhere, is to check the date and time of issue. I have often seen out of date forecasts being studied carefully by yachtsmen. Marina staff sometimes seem unaware that a forecast issued three days ago for today will be less reliable than one issued today.

Telephone Services

The Marine Rescue Service provides automatic forecasts at local call rates in Swedish currently on 0771 535 400. You must provide the area of interest by speaking it in answer to an initial question.

You should give this in the form used in the Swedish language forecasts (e.g. Mälaren or Landsort till Haraldskär)

The response is in two parts. the Synopsis followed by four sets of wind direction and strength predictions covering the next 24 hours for the area you have selected.

The synopsis may be difficult to grasp but the second part is in the same format as the usual VHF coastal forecasts. Wind speeds are in metres/sec..

A good service in Finland is the SMS service. For 56 cents (Euro) you can get a four hourly forecast of wind speed and direction (in English) for two days out. You simply send an SMS to 16161 with the text SEA xx, where xx is an area number. The area numbers are printed in the chart packs.

Note that this service only works to local mobiles (not UK ones)

Appendix 1 - - Useful VHF Channels, VHF station locations and areas used

These have been provided partly by CA Baltic section members. The table and maps includes stations relevant to "Approaches" to the Baltic.

Most of the coast regions are described in terms of capes and headlands. You will find them on the chart you are using. The regions are taken in a clockwise direction. The South and West coast forecasts start at Utklippan and finish at the Norwegian border. The East coast forecasts start at the Finnish border and ends at Utklippan. The sequence is interrupted by Gotland Farvatten (Gotland sea-routes). After the main sequence the relevant lakes are taken in the order :- Vänern, Vättern, for the west coast or Mälaren, Hjälmaren for the east coast. Finnish VHF Channels and location of stations are on their website.

This page is partly culled from Cruising Association members with Baltic experience. Cruising Associationmembers can obtain Guides to the area and other information collected by the Baltic Section of the Association. A site that will interest putative Baltic sailors is run by my friend and fellow Hallberg Rassy owner, Ivan. His site contains much useful and hard won experience. It is well worth visiting and more amusing than my pages. A Swedish sailor has informed us that, if you become a member of Sjöassistans (www.sjoassistans.se), you get access to something called sjöportalen, containing weather, coastal weather, navigational warnings and a lot more, such as bridge heights and openings etc. All this is available in a format optimized for viewing on mobile phones. Sjöassistans is partly a marine rescue organisation, but offers a lot of different services to members ? e.g. towing when engine fails, help with fuel, phone service for all possible info that might be needed at sea, medical advice and help, help with engine- or rig-related problems etc. Membership is 620 SEK a year.
