JUNE 2005
Forward to July 2005

The first half of the month saw little by way of noteworthy weather with the exception of a number of cool nights and the continuing dry theme. Daytime temperatures were consistently around ±3C of the average with the exception of a brief warm spell on the 8th to 10th, and the weather unremarkable.  On the 18th, high pressure settled over the southern UK before slipping SE, allowing very warm air to push over the southern half of the UK. The maximum temperature of 31.9º on the 19th was a new June site record high since recording began in 1984. The second half of the month was mostly hot - pushing the monthly temperature above average - and often humid. However, thunderstorms were scarce and the total rainfall for the month was significantly below average for the 8th successive month.

* = 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, s = steady, r = rising; r = rapidly, 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.
