April began cold, with the temperature not reaching 10[°Con the first two days. Slight air frosts on 2nd & 3rd were the only ones in the month (-0.7°C & -1.3°C). However, on the night of 3rd/4th unsettled, milder conditions moved in bringing just 4.4mm rain. The wind was still light between west & south for a week or so. The temperature reached double figures; up to 18.4°C on 11th. More rain, 7.3mm, 2.3mm & 1.0mm was recorded on 6th,8th & 11th. The last 1.0mm proved to be the final rain for the month (apart from 0.3mm early on May morning*). High pressure and light winds dominated the rest of the month bringing much warm sun but also a lot of cloudy days when the very light winds failed to disperse the cloud. The temperature exceeded 20°C between 15th-17th, with a maximum for the month of 21.5°C on 15th. Apart from 30th (1.6°C with a ground frost), night temperatures during this period were mostly in the mid to upper single figures. There was a total of two air frosts and four ground frosts throughout, all very slight. Overall, April 2022 was mild, warmer than 2021 but cooler than 2020 and 1.45°C above my long-term average. There was a mixture of warm sun and overcast, determined by the very light winds. It was very dry, the driest April since 2017 and the driest month since May 2020.
