MONTHLY SUMMARY
 
December was the mildest December recorded here in the 3 year history of my measurements.
A very changeable, atlantic dominated month, characterised by low pressure systems bringing
high winds and spells of rain. A calm anticyclonic spell brought a cold, sunny and settled
build up to Christmas, although it became foggy and cloudy in the last few days of this spell
including Christmas and Boxing Day. The weather became mobile at the end of the month, with
another stormy night on New Years Eve.
 
Rainfall was 71mm, much higher than 2004 and 2005, the warmest December day so far recorded
on the 14th at 13.8ºC, no snow days, and six air frosts. Surprisingly on the 21st the temperature
never climbed above 0ºC at all, meaning only the second “ice day” ever recorded here.
