Maidenhead (Berkshire, UK): Recent observations and the latest forecast from the author of these pages
July 2013 - a long hot spell breaks a run of six consecutive cold months
Following the period January- June 2013, during which the mean temperature each month was below average, July brought a welcome spell of hot weather to the UK, including Maidenhead.
A temperature of 31.4 C was reached in Maidenhead on Saturday 13 July - the highest temperature since 31.4 C on 26 July 2006. On 27 July 2006 the temperature had been as high as 32.7 C following 35.1 C on 19 July 2006.
Sunday this year followed a sequence of warm/hot days during which the maximum temperatures in the town had been as follows:
4th 24.1 C
5th 26.0 C
6th 27.4 C
7th 29.5 C
8th 27.2 C
9th 27.1 C
10th 24.9 C
11th 23.0 C
12th 25.5 C
13th 31.4 C
With maximum daytime temperatures expected to remain around 28 C for much of the forthcoming week - and possibly into next weekend - this current spell of hot weather is on target to be the most memorable hot spell since July 2006. That month the 11th-30th was unusually hot with 30 C being reached on 8 days - following a warm June.
In 2010 the 13 days from 21 June to 3 July were almost as warm - with the temperature climbing to a high of 29.6 C on 27 June.

Note that the observations refer to the period 0900-0900GMT while the forecasts are for 0600-1800GMT maximum and 1800-0600GMT minimum temperatures.
In these two charts the red line shows the mean of several forecasts. The thin blue lines show the range of values predicted by the different NCEP (ensemble) forecasts, while the dark blue lines give an idea of the standard deviation. The rainfall total is the six-hour total ending at the time indicated (the dates along the bottom axis are written at 0000GMT).
The increase in spread of the forecast values in the previous two charts gives an ideas as to when the forecasts become to be unreliable.
Maidenhead's daily and monthly weather reports
Local climatology (updated January 2009)These two sets of data have been compiled using observations made at my home weather station since June 1988. This is a suburban site and is slightly warmer than Hurley because of this. Also, the observations were made at a generally later date than those of Hurley, and the extra warmth is also an indicator of 'global warming'.
The following information has been extracted from the daily weather observations made at Hurley during 1953-1992. This is a rural site.
