Wanstead Weather: 2013 review

The mean temperature of 10.7C makes 2013 0.5C colder than the 1981-2010 average. And makes the year 46th warmest in the series going back to 1881.
Rainfall of 554.9mm is 92% of average for a year in this area, making it the 68th wettest in the series back to 1888. Some areas of the British Isles have been considerable wetter – this just reflects how variable rainfall can be.
Though the year appears fairly average it masks some notable events…
A couple of notable falls of snow were observed in January and February

A couple of notable falls of snow were observed in January and February

January saw a couple of notable falls of snow, the first of which arrived on the 18th. By the morning of the 21st there was 13cm lying.

February saw a further snowy spell with 5cm falling on the 10th – but this only lasted a couple of days.
The mean temperature for March of 3.6C made it the coldest since 1892, the 3rd coldest in the series since 1881.
After a cool and dry spring and early summer July surprisingly turned out to be the warmest since 2006 – the mean temperature of 20.7C being the third warmest in the series going back to 1881. The warmest day of the year occurred on 22nd when 34C was recorded. This was followed by a very potent thunderstorm in the early hours of 23rd.

An average August and September saw a couple of notable rainfall events with 32.8mm on 24/8 and 32.6mm on 13/9 being the the 27th and 28th highest 24hr totals in a series going back to 1961. In the August event Maldon in Essex saw in excess of 100mm leading to flooding. What made it more noticeable is that these events occurred during dry spells.

The end of October saw the St Jude storm blast through Wanstead. The strength of the gusts saw the demise of a few mature limes on Christchurch Green as well as trees in Wanstead Park.
