Sohin Hwang checks the sunshine record - the warmest December in 200 years provided little sun and was well below average
The School's Observers at the Radcliffe Meteorological Station have recorded the warmest December in 200 years. The average temperature last month was 10.8°C, an extraordinary six degrees higher than the long-term average of 4.6 degrees. This December's average surpassed the previous warmest, set in 1852, by over 2.5°C.
The maximum temperature for any single day was also broken. The previous record of 15.2°C reached in 1985 and 2001 was overtaken twice with 15.8°C on the 17th of the month and 15.9°C a day later.
Milder nights resulted in only one ground frost being recorded, four fewer that the previous lowest record of 5.
The cloudy conditions which prevailed for much of the month ensured that December was unusually dull. A total of 35 hours of sunshine was nearly 15 hours below average, and only just over a third of the 2014 record when Oxford citizens basked in just under 100 hours of December sun.
Despite the prevalence of clouds Oxford did not experience the extreme rainfall suffered by other parts of the UK this December. The city's rainfall was only a little above the long-term average of 56mm.
