April was an extremely dry month (the driest of any month in my 21-year record) with only 4mm of recorded rainfall, i.e. 6% of the average monthly amount.

This occurred on only three days: 3.3mm on the 3rd, 0.2mm on the 4th and 0.5mm on the 11th. That’s 19 days without any rainfall recorded. It was also one of the warmest Aprils with a mean temperature of +3.9C above the 1981-2010 average.

May started as April finished with no rainfall recorded until the 6th – making 24 continuous days without any rainfall recorded. The rain that followed was mostly over three days: 4.2mm on the 6th, a massive 24.3mm on the 7th (nearly one inch), and 2.1m on the 8th. So most of the month’s rainfall occurred over just three days…
