By the 13th May we were heading towards a record low average temperature for May. May 1996 ranks as the 8th coldest since 1772 and we were in line to match or 'better' that record. The coldest May since 1772 is 1817 and the graph shows the comparisons for the 13th May this year.

The second half of the month turned out to be warm and in the way things do evened up the cold start, so we finished with about average temperatures for May. It did create a difficult start to the growing season though with late frost damaging potatoes, fruit blossom and any other tender plants that thought May meant an end to cold and frosty nights.


May also turned out to be a very dry month which combined with cold frosty nights made for a difficult and slow start to the vegetable growing season. A couple days with light rain at the end of the month did little to boost the monthly rainfall figures. We had just 9.6mm of rainfall in the month which is about 20% of our average May rainfall.

It’s the first month of the year for seriously harvesting fruit and vegetables that have grown this year rather than over-wintering. Setting fruit also gives a hint of things to come.


 May 2010 Weather Summary


May turned out to be a month of extremes. Temperature wise it turned out (to steal from footballing terms) to be a month of two halves. The first half unseasonable cold followed by a second  half to the month of unseasonable warmth with some days bordering on hot.


It's the time of year when the plot takes on a green and pleasant look and winter’s bleak look disappears. This is especially so of the areas planted up with perennials and trees and fruit bushes. The rush in growth of summer vegetables has still to take place.
