It is due to a persistent spell of northerly winds, due to a blocked regime in the Atlantic. It is unfortunate that the blocking highs keep forming to the west of us bringing cold winds down from the north. This is not unlike 1996 which was cold from winter through to mid May (yet the summer was warm and dry).
The problems will start if the summer turns out to be hot and dry as we have had a very dry spring so far and we will be looking at water shortages if this keeps up through the summer.
