July 2012 - A month of two very different halves

Postby Nick Gardner » 2012 Jul 29, 18:13

Another rather lovely day here, continuing the generally sunny theme that started on the 19th.

It has been dry too, no rain has fallen since the 18th and the ground is now quite dry. Such a contrast to the first half of the month when everything was sodden.

July 1st - 16th
Mean maximum = 18.2°C
Rainfall = 115.4 mm
Sunshine = 44 hours

July 17th - 29th
Mean maximum = 22.7°C
Rainfall = 7.4 mm
Sunshine = 131 hours.

The above figures show it all really.

The holiday-makers down here have really done well this year, and I am glad as the previous peak-summer season weather has been poor since 2006 (though last year wasn't as bad as the previous years).

The increase in sunshine from the first half to the second half was quite dramatic, and saved the month from being one of the most miserbale summer months imaginable (though June was dire with just 106 hours of sunshine!).

July 2012 Sunshine:
1st - 15th = 40 hours (12% of the total possible)
16th - 31st = 146 hours (55% of the total possible)

Anything above 50% is in the 'sunny' category. Above 60% and we're shooting along.

Months in the last 2 to 3 years with sunshine amount 50% or greater of the total possible:
June 2010 = 64%
April 2010 = 62%
September 2010 = 51%
April 2011 = 59%
March 2012 = 51%

Many came close with 48% and 49%.

The percentage of the total sunshine possible is an excellent way of indicating how 'sunny' a month is. For here, I can divide the 'sunniness' of a month, very roughly as the following:

<20% = extremely dull (rare)
20% to 30% = rather dull
30% to 35% = duller than normal
35% to 45% = normal
>45% = fairly sunny
>50% = sunny
>55% = very sunny
>65% = Extremely sunny (not happened yet. Sunshine recording started Dec 2006).
