Sunshine Hours above are approximate only and calculated from the solar radiation sensor's limited exposure to direct sun, with no allowance for visual only observation. As the sensor receives only between 30-70% of total possible sunshine exposure depending on time of year, the figures above can be very significantly less than the actual sunshine duration.
* = 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"
