Surely you have have to look at average maxima and minima given the well above average rainfall which was always likely to raise the minima temperatures. Based on the Met office data the average maxima from 2004 to 2006 for June were 1.6, 1.7 and 2.6 above average, but just 0.6 this year. In terms of recent years that is a crash.

Croydon, surrey Normal grey start to the day, very humid, lovely clear end to the end, with even a hint of a sunset

"The greatest thing about the British weather is it's unpredictable." True. The netweatherforecast is that it is supposed to be raining at this moment in Croydon. In fact except that for some early morning rain, there hasn't been any rain today, it isn't even been overcast, quite a bit of sunshine and blue skies.

Surprisingly they are not playing on the middle Sunday at Wimbledon, despite the fact that they haven't completed 3rd round matches and got so little play today. The problem seems to be the beginning of next week, the weekend forecast for the finals isn't too bad at present.

Paul Sherman' post='1012305' date='30 Jun 2007, 09:42 AM']Interesting posts from our "Guest" posters although this period of unstable weather was probably not that hard to predict if you think of it logically. The Jet Stream is a Chaotic system, and as such after such a dry April the chaos theory was always going to throw up this sort of 8-10 week period. If that is the case why was long range Netweather forecast dated 17/5/2007 so wrong. I quote "Rainfall will be below average in Southern Britain, particularly during June and July. It will be closer to average in North and Western parts and perhaps above average in August. The Sea Surface Temperature profile in the Atlantic favours High pressure development to the South West of the British Isles and we expect the Azores High to be the major factor in bringing largely dry and settled conditions for the most part in June. Blocking over Europe and winds from a southerly quarter were the dominant factors in bringing exceptional warmth in July last year, and whilst this scenario will feature again this Summer, we would not expect the same sort of prolonged hot periods." Anyone know why the long range forecast hasn't been updated as was indicated towards the end of June?
