Above: weather and wind situation for midday GMT Sunday

Summer is here in the UK this weekend forecasts Libby Greenhalgh
A high pressure system will dominate the weather over the south of the UK for the next couple of days with high temperatures and plenty of sunshine, and hopefully a sea breeze. With the high pressure centred over southern UK there is very little gradient flow to provide any wind at the surface. However with the temperatures on the increase and the sea temperatures still relatively cool we could see the start of a sea breeze. Sea temperatures in the Solent area at the moment are around 10 to 12 Celsius and with forecast daytime temperatures reaching up to 21 Celsius over the weekend we have a sufficient temperature difference to develop a sea breeze. Below: weather for 1200GMT Saturday The sea breeze will only be light as there is no offshore component aloft to assist in the generation of a sea breeze. To add to that the Solent often has two competing sea breeze directions the SE and the SW. Anyone who participated in Cowes Week last year will have experienced being becalmed as these two directions fought for dominance. The result inevitably was the SW. So, for both Saturday and Sunday expect a weak sea breeze development. It will slowly develop from 11am at bout 5 knots increasing to 8 knots by early afternoon, from the SSE and will gradually veer. Once settled in the SW the wind could build to 12 to 15 knots in the late afternoon. Other websites to check out...
