April 2018: four seasons in one month

I normally headline these monthly reviews by referring to the most notable weather but this April, often a fairly non-descript mid-spring affair, offered pretty much every type of weather. bluebells

The mean temperature finished 11.7C, 1.9C above average and the warmest for four years.

Rainfall was 55mm, 129 per cent of average and the wettest for 6 years.

Sunshine was just 110 hours, the dullest for 40 years and the 16th dullest since 1881.

Hidden in the positive monthly anomaly was the warmest April day in a local record going back to 1959: 29.1C on the 19th – a figure that represents a positive anomaly of 15.5C and occurring at the start of the warmest April heatwave since 2011. It was remarkable that such an anomaly happened so close to a record negative anomaly the previous month.

Yet, just over a week later, temperatures lurched cold again with one of coldest last days of April on record. Though the 24hr record wasn’t broken the noon-6pm record going back 60 years was beaten.

The wettest day occurred on the 9th with 10mm falling.

Air frosts: 0, Ground frosts: 1

April 30th provided a timely reminder after the heatwave to ne’er cast a clout till May is out. A low pressure system in the North Sea brought a thoroughly miserable day though even more rain fell across the Channel.

It was a month with some amazing sunsets. This one, on April 30th, happened just as the sky cleared before dusk

  1. Good old British weather! As a gardener friend of mine commented yesterday on the “late” cherry blossom up here, “it’s just like when I was a girl”.

    Nice sunset shot!
