AUGUST 2005
September 2005

1st - 7th:  Changeable. Long sunny spells limited to the 3rd and 4th, followed by a wet morning with moderate rain on the 5th and a cool weekend 6th/7th.
8th - 11th: Long sunny spells and dry except for a light shower on the 10th.
12th - 14th: A cloudy weekend, feeling cool with little sunshine. Moderate rain on the 13th, light rain shower on the 14th.
15th - 18th: High pressure to W and E brings a brief warm spell with long periods of unbroken sunshine.
19th - 25th: A very unsettled and largely cool period. A very active cold front sweeps through the region on the 19th ending the short warm spell. Very dull with moderate to heavy showers lasting most of the day. More prolonged heavy rain on the afternoon of the 22nd, and on the 24th further downpours and strong winds from a deep low passing to the north of Scotland ("Oedipus" - a secondary depression centre associated with ex-Hurricane Irene).
26th - 31st: Strengthening HP across the southern half of the UK brings more settled conditions. Unbroken sunshine almost throughout from the 28th - 30th and the month ended on a hot note.

* = deviation from 20 year average. The monthly mean is calculated from all logged temperatures and is not the simple mean of the daily minimum and maximum.
THW = Shaded Heat Index calculated with cooling/warming effect of wind and humidity to give an apparent temperature.
THSW = Unshaded Heat Index calculated with cooling/warming effect of wind, humidity and full direct sunshine to give an apparent temperature.
EVAPO-TRANSPIRATION is drying effect due to sun and wind, and is equivalent to "negative rainfall"

Solar Rad(iation) reading indicates the state of the sky (approximately) at just after 12h00 GMT as below:
1 - 10 = Dull overcast; 11 - 20 = overcast; 21 - 49 = cloudy; 50 - 74 = hazy or interrupted sunshine; 75 - 100 = bright uninterrupted sunshine
† Barometer trend: f = falling, st = steady, r = rising; q = quickly, s = slowly

'WIND ROSE' PLOT FOR THE MONTH
The 'petals' represent wind direction and the length represents frequency, i.e. in this case winds from the SSW were the most common, followed by the N.

The colours represent the strength of the wind, with black being weakest through blue then lighter colours (cyan, light green, yellow, magenta, red) being stronger.

This data excludes 'calm' readings.
