Title: Good Monthly Forecast?
Post by: markt on July 08, 2009, 05:23:38 pm
Anybody know good sources for a 'monthly forecast'?  I'm off to the Isle of Anglesey for a week on the 8th august, principally to watch perseids from dark skies and are curious what the weather Gods have in store for me.

I know the BBC do a monthly forecast but i'm sure there must be others out there.  Any you folk can help with some suggestions?

Thanks, Mark :)

You can be pretty sure that any conventional forecast more than 5 days ahead is no better than random noise. Seasonal trends forecasts are if anything even worse.

In the UK, in July & August, you can be 95% sure that:

1. The Sun will shine for at least a few minutes on most days

2. Rain will fall on at least a few days

3. There will be a breeze but violent winds are not likely

4. The daily maximum temperature will be between 15C and 35C, and the daily minimum temperature will be between 5C and 20C
