Ive just trawled through some of my ramblings, and this is something I posted six months ago....
Lots of charts at...
magicseaweed.com/UK-Ireland-MSW-Surf-Charts/1/
Or the basic pressure charts at...
www.met-office.gov.uk/weather/charts/index
And the very quick guide to forecasting...
This is from the weekend just gone -
A - Low pressure out to the west of the UK sending waves towards us. The more lines (isobars) there are, the deeper the low, and the bigger the waves.
B - A bit of distance to travel. This means the waves clean up, and the strong winds arent on top of the waves which would muck things up.
C - A high pressure to the east of us (this isnt a very good high pressure). This should give gentle winds and maybe even some sunshine.
The track of the winds will follow an anti-clockwise direction around the centre of the low (basically following the isobars) so you can tell when its going to be onshore (bad) or offshore (good).
To work out which beach you need to be at you need to remember that waves will travel 'out' from the centre of the low so a direct line between the low and for instance devon will give big waves. But if its a real deep depression then the swell can wrap around so the south coast might get some, or if the low if further north it can wrap around ireland and get to devon and cornwall.
Oh, one last thing - the other thing you need to look at is the period. This is the gap between waves (and you can predict it, or find it on magic seaweed). A period of <10seconds will mean choppy waves coming at you without any real shape, while >10 seconds, and preferably 15s, means between the waves will be nice and clean - easy to paddle out, nice to sit in, and good shape waves when they arrive
Okay, thats the basics... there's a lot more to it than that, but that should do you for now!
And just to add that you need to be looking at tides as well, particularly in summer when its small. The swell will
tend to pick up on the push (an hour or two after low tide as it begins to push in). And of course you need some local knowledge as to which break you should be at for shelter from the wind, the beach that will pick up the swell etc etc.
