THERE was 15C difference between the hottest and coldest days last month, the latest Met Office figures show.

The coldest day was May 5, when despite full sunshine, it only reached 8C at the Met Office’s base at Ronaldsway.

But on May 25, thermometers topped 23C – the second warmest May day on record.

A Met Office spokesman said: ‘Much of May saw a northerly origin airstream affecting the British Isles with temperatures way below average, often struggling into double figures, even when the sun was shining.

‘The last week saw a change to a more continental origin and temperatures rose into the 20s.’

There was 39.6mm rainfall, compared to a long term average of 50mm. The wettest day was May 10 with 12.5mm.

There were 250 hours of sunshine – about 25 hours more than average. The best day was May 26 with 15.5 hours.

The wind speed averaged 10.1 knots, a little below normal. There was no hail at Ronaldsway, but hail showers were reported from other parts of the island early in May. There were three days with fog and four with a ground frost.
