Frank Singleton's Weather and Sailing Pages

Updating

TLinks have been checked most recently in February 2020 but is always likely to have errors due to website, even official ones, changing with no prior warning. Information about broken links is always welcome.

Introduction to Frank's Weather Site

Weather determines where we sail to, when we sail there and if we sail at all. This site is a guide to marine weather forecasts and how to use them. Understanding marine weather forecasts and about weather at sea are both essential to safety of vessels and their crews, especially those of sailing yachts and leisure motor boats.

This site applies my long and wide experience in meteorology and sailing to help others to whom weather forecasts, and marine weather forecasts in particular, are mysteries.

Over the years, when I have seen a need, I have added other pages that might be of interest - including the vexed issue of climate change.


A cruising yachtsman’s Viewpoint


Anhinga on passage from Port Joinville, Ile d'Yeu to Les Sables d'Olonne on 4th June, 2017. Note the line of sea breeze cloud over the coast.
My hyper-critical son, a RS8OO sailor suggests that a little more boom vang tension, perhaps?

To us, in our Hallberg-Rassy 34, Anhinga, cruising is all about sailing enjoyably and safely. That means not getting caught out in strong winds, say over Beaufort force 7. It means being able to decide where we want to be if bad weather is expected and getting there in good time. It is better to be in port wishing you were at sea than being at sea wishing you were in port.

It definitely does not mean really heavy weather sailing as shown here!!!

Sections on this site

The links below and always visible in the Left Hand Sidebar. They will take you to the various areas of this site.



GMDSS Weather Forecast Services
GMDSS (Global Maritime Distress and Safety System) services are available worldwide via VHF, NAVTEX, INMARSAT and SSB radio. These pages relate to Europe, the eastern North Atlantic, the Baltic and Mediterranean.

Marine Weather information on the Internet
The Internet is an alternative source of forecasts and a provider of information not covered by the GMDSS. However, it is not an operational service. It will not always be available or it may have high communications costs.

GRIB Files - all you want to know
An increasingly used weather resource, often misunderstood. These pages will help

Information for specific sailing areas
Forecasts and weather in European areas and the Atlantic.

Understanding Marine Forecasts
Getting marine weather forecasts is only the start; understanding and knowing the terminology and how best to use forecasts are the real problems.

What is behind the forecast
Weather prediction, limitations, the data used, and observing the weather.


Understanding Marine Weather
Much of our weather is often rather small scale. Some of these pages challenge conventional wisdom.

Marine Weather Communications
For many, the BBC Radio 4 shipping forecast is all they ever use but there are many other forecasts available - given the right communications and knowledge.

Climate Change
The issues, the arguments, the experts.

General Information, History of meteorology
Beaufort Scale, Meteorological History. I find these pages interesting - and hope that you may do also.

Some basic theory
Coriolis, Formation of pressure differences, why air moves, heating and cooling of the air. The importance of Latent heat.

General Weather and Sailing Links
National Weather Services, other sites, Clubs and Associations, Commercial links.
