The mean December temperature in Penzance is now running 3.1C above normal...

Our mean, so far, is 7.5°C which is 2.6C° above our fifteen year average
for December and the highest for any December in that fifteen years.
Last years December mean was 6.7°C, the previous highest.



Overall mean 6.7C here, well above the estimated December mean of 3.8C
(I don't have any useful long term temperature data for this location).
Still a very dry month with only 3.5mm rain up to 1126h today
