Pennine Software Sea State Page

Information useful for sea kayakers and others in small vessels. The north Atlantic charts linked here give the best insight into British waters - if you are having a holiday in the sun, you can find a variety of charts for the Mediterranean and elsewhere via westwind.

The latest NOAA/NCEP N. Atlantic wave model hindcasts:
10m wind speed/directionSignificant wave height
& peak direction
Wave period & direction

NOAA also provide forecasts for the same area. These were generally available 5 hours 45 minutes after the time of the data from which they are forecasted (plus or minus half an hour - it was very rare that they are up to an hour late). So if it is 9 a.m. in the UK, you should expect the times below to be offsets from midnight UTC just gone...

However, recently I have noticed a lack of updates, and stuff seems to be appearing up to a day late - so check the start times on the images above and work forward from that time to deduce which forecast you want from the left hand table. I've recently discovered the meteosim forecasts (right hand table) which may update more promptly (not enough experience of them yet), but only go 72 hours ahead:
