2010 was around 1 degree below the long-term average (the main contribution to this being December. Rainfall was around 15% below the long-term average(March, June & December being especially dry)

DECEMBER 2010-----A truly remarkable month, the sort of conditions experienced, perhaps only occuring once a century. The max.temp. was 5.4 down on normal, the min. temp.an incredible 6.9 degrees down (anomalies of this sort are very rare indeed) Snow fell on 12 days & lay on the ground for 27, with the maximum depth 21cms. There were 27 air frosts & 30 ground frosts. However, as pointed out before, we need only go back to 1995 to find a colder individual day & night than in 2010. Nevertheless for persistent cold, December 2010 will stick in the memory for decades to come.
