It's Brighton Pride this weekend (Friday to Sunday), and unlike last year when there were showers around, this year is looking good!
Friday will bring plenty of sunshine, highs up into the high teens, maybe squeezing 20c with a fairly light breeze from the south or southwest, cooling down to 12c overnight so cool enough but not too chilly if you're out and about or are camping.
Saturday may see a bit more in the way of cloud moving through from time to time, but still some decent sunny spells and temperatures very similar to Friday's values. The wind will be a little brisker than Friday but not especially so.
Into the final day, and it's set fair once again, some cloudier bits, some sunny spells and with winds a touch lighter again and highs climbing a little higher to 21-23c it should be a great end to the event.
