I use http://wwwa.accuweather.com/index-world.asp?partner=accuweather&myadc=0 and find it very good on the windspeeds. It gives forecasts for 15 days ahead. The next 5 days or so have hourly weather (including windspeed) available. I have found them to be very good, in that they provide average and gusts, where gusts can be double the average. The BBC etc seem to use the average alone, which can be misleading. I don't necessarily rely on the hourly prediction, but it gives a good idea of what will pass through on a given day.

There is a 'home page' for UK, USA, World, etc. And sometimes it defaults to 31 Dec in error - just press Refresh (F5) and you seem to get the proper day's weather shown.

Cheers
Simon
