Commentary

January 2021 Felt cold and wet, and it really was. We had a new record for rainfall in January - by a whole 0.2mm more than fell in 2014. Maximum daytime temperatures were down, and we had more frosts than might have been expected. Some snow mid-month, but not deep and did not stay long.
February 2021 The second week was really cold - dubbed "The Beast from the East II" to compare it with 2018. The cold was again caused by continuing cold air being blown from Siberia way. This beast was not quite a cold as the last one, but lasted slighly longer. From the 7th we had about 20cm of snow which stayed on the ground for 3 or 4 days. It caused a lot of businesses to close and postponed Mavis's covid jab. There were 2 "ice days", when the temperature did not get above freezing. Apart from that, February was OK, with some quite springlike weather later on.
March 2021 Started wet, finished dry. Started cold, finished hot. Started dull, finished bright. Apart from that, the key feature was that March 31 2021 saw the hottest day I've recorded in a March - 21.2°C, compared with the previous record of 20.6°C in 2005.
April 2021 An interesting weather month. Most natable for being cold, especially at night. We had 13 nights when there was an air frost, as opposed to the average of just under 4. It was, on average, the coldest April I've ever recorded, about 1½° colder than my lowest previously recorded coldest April. It was also very dry - we only had 1mm or more rain in a day on a single day, and overall we got about 1/10 of average rainfall. Curiously it wasn't the driest April ever - that was 2012 when no rain at all fell.
May 2021 Another cold month - just the coldest I've recorded at just over 0.1°C colder than 2013. A frost early on, which accounted for some of our tomatoes. Also wet - around twice the average rainfall, and a period of 15 days in the middle of the month when I recorded some rain - albeit as little as 0.2mm on some of the days. Ended warm and sunny just in time for the late Bank Holiday.
