Marine Weather Forecasts by Email and FTP

About this page

Details of some of the sources of marine weather forecasts obtainable via compressed emails and FTP.


Email or File Transfer Protocol (FTP) are cost effective ways of getting information while away on the boat. They do not require broad band Internet access and avoid using web browsers with annoyingly irrelevant pictures, adverts and ornamental features.

They can be used with low bandwidth when marina WiFi is slow or you are using a satellite phone. They can be used with GPRS over a cell phone.. Email is the only Internet facility for Blue water sailors using HF/SSB with a modem.

Some very basic notes on HF and HAM radio are at my page Internet and Email Connections.

File Transfer Protocol

Basically, FTP extracts digital or image data from service providers and translates them into a compressed digital form. These data can be transferred directly from computer to computer without using a browser. Often easier for sailors is to get the FTP data as email attachments.

The US NWS has an FTPMail service. Although simple to use, the volume of instructions and introductory material is daunting. Other services build on this in a rather more user friendly manner.

Some of these services are described briefly here.

Saildocs Texts of Web pages

Saildocs] is a free-to-all text retrieval service provided by SailMail. To use, send an email to .
Subject - anything.
The message should read
send http://www.xxxxxxx.
Simply copy the address of a web page containing the forecast that you want. These can be taken from my Internet text ======================================== pages]] by right clicking on a named link from the frame and copying the address..

As an example, a message saying
will provide all the text for the UK Inshore waters forecast.

Within a minute or so the reply email will contain the all the text of the web page stripped of all the extraneous information. Met Office pages are commendably small downloads, but the text on most WebPages can be received as an attachment less than 4 kb.;

Several pages can be requested at a time. This will work with many WebPages, not just marine weather pages. Prime exceptions are all texts of Météo France marine forecasts and several German ones.

Météo France Navimail Text service

Since Metéo France blocked access to its texts by SailDocs, this is the only way to get their forecasts by email. For details see my Navimail page. It is much less user-friendly than Saildocs and more restrictive in what it can provide.

MailASail GRIB, Text and Chart Responder

This is easier to use nut has fewer options. There are other GRIB services, some on repayment but have little if any advantage over these two.
