December 2008 normal weather again

The daily weather log

Weather log December 2008

Unlike last December’s cool, humid, cloudy and rainy weather, this December’s weather was very close to normal in every way. There was a time in the middle of the month when the 7-day temperature was rather low, with low humidity and clear skies, but this was balanced by warmer, moister times.
Days were slightly cooler than average, but the very hottest day was remarkably cool: only 35.0°. Only two Decembers in a decade failed to make 35°. Even October and November this year had days warmer than 34°!
There were eight rain days, the wettest having 38.2 mm.
