December 2015 was easily the mildest December on record. The mean of 7.8 degC was 3.9 degC above average. Nationally it was also the wettest calendar month on record. At Durham it was the wettest December since December 1978.
Storms propelled by the jet stream were mainly to blame, it says, with contributions from the El Nino weather phenomenon and man-made climate change.
Numerous species of plants flowered months early, believing it to already be Spring. There were 4 nights when the temperature remained above 10 degC.
Christmas Day was the wettest day of the year in Durham in 2015. Indeed it was the wettest Christmas Day on record here since records began. There was 45.4mm of rain recorded over the Christmas Day and Boxing Day period. This was all due to Storm Eva.
