Settling down and warming up for a time, more changeable thereafter.
July hasn't really delivered what you might expect; just ask any of the golfers at The Open who really struggled in low temperatures, rain and strong, gusty winds.
The low pressure system responsible for that is now moving away towards Scandinavia allowing pressure to rise across the UK. As conditions settle down, temperatures will rise.
Average temperatures for the time of year are in the range of 16C in Stornoway to 23C in London, temperatures will be higher than this during the middle of this week.

“Warming up.”
Apart from a little rain in the northwest of the UK early in the period most places will be fine and dry.
Atmospheric pressure will rise steadily day by day, peaking midweek and then falling back. As pressure rises, the winds will ease, continental air will drift across the country and there will be some lengthy spells of sunshine. With these conditions it will feel quite warm.
Thursday looks like the warmest day of this spell, with 17C in Stornoway, a warm 22C in Glasgow and a very warm 26C in London. However, by early Friday conditions will break down as some thundery rain begins to spread in from the west.
As the weekend develops we'll lose the continental air and as westerly winds pick up, the Atlantic influence will return.
Monday 28 July 2008 to Sunday 03 August 2008
“Generally unsettled.”
Despite a weak ridge of high pressure building in from the southwest conditions generally look unsettled.
Rainfall amounts are likely to above the seasonal average and with the associated cloud, sunshine amounts will be a little bit below average for the time of year.
Monday 04 August 2008 to Sunday 17 August 2008
“Changeable.”
A mobile, westerly airstream will cover the UK. There will be more rain than what might be expected for the time of year and consequently sunshine amounts and temperatures will be somewhat lower than the seasonal average.
Het MetOffice gaat dus voor tijdelijke zomerwarmte waarna onder begeleiding van een westelijke stroming de wisselvalligheid opnieuw terugkeert. Daarmee zou deze zomer dus definitief in het water vallen. Op dit moment staat de zomer op de 43e plaats in de lijst van alle zomers sinds 1901 en is daarmee vooralsnog normaal te noemen. Er hoeft echter maar weinig te gebeuren om het alsnog als 'koel' te classificeren.
