Warmest March I have recorded. Mean temperature 10.2°C. Maximum 21.2°C, which is teh warmest March day I have ever recorded (20th). Only 2 days in which the temperature failed to reach 10°C. One of those was 9.9, the other 9.4. Month's minimum: 4.1°C.
Compare that to March 2013, the coldest I have recorded. Then, the mean was 3.6°C and there were only two days in which the temperature did struggle above 10°C. There were 13 frosts that month.
My machine doesn't record hours of sunshine, unfortunately, but I reckon it was much sunnier than usual.
