* = 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"

Note A total hosepipe and sprinkler ban remains in effect in the Mid Kent Water supply area until at least 30th November
1st - 8th A mild but stormy start to the month with frequent and prolonged heavy rain showers. The 2nd and 3rd were sunless but the 4th was sunny for most of the day. The 6th was dull and wet with moderate rain most of the day.
9th - 12th Continuing changeable. Long periods of sunshine on the 9th and 12th but breezy, sunless days on the 10th & 11th.
13th - 20th Signs of a change from the dominant mild maritime sourced weather as it turns cooler but more settled. With high pressure building there is a cool wind on the 16th but uninterrupted sunshine through the 17th to 19th. The minimum of -4.3ºC on the 20th was the lowest in November since 1993.
21st - 23rd Anticyclone dominates with cool frosty nights and some freezing fog. Mostly sunny with precipitation largely from fog and frost condensation.
24th - 30th Low pressure in the North Sea brings strong, cold, polar winds. Mostly dull. Slightly milder maritime air and rain arrives on the 30th but the rainfall total for the month remains much below average.

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
November wind rose
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.
