Weather report: May was 'one of the warmest on record'
PUBLISHED: 14:33 12 June 2018
Although the first day of May was sunny with a few showers, it turned cloudy on May 2 with an area of rain moving across the region along with some strong winds of up to 40-45mph.
It was an average start to the month in terms of temperatures with highs of 13-15C but winds turned to the south-east and became light, leading to prolonged spells of sunshine and warm temperatures through until May 9.
Initially a few grass frosts affected the west of the region overnight as high pressure built, but with warm daytime sunshine then the night time temperatures slowly rose.
In the warm spell it was the hottest early May Day Bank Holiday weekend on record for the UK.
Temperatures cooled back down to near average on May 10 and 11, as a cold front brought some rain overnight and fresher air from the Atlantic. It stayed cooler and cloudy over the next few days with some spots of rain at times.
The middle of the month brought some sunny skies and slightly warmer temperatures over inland areas but mist, fog and low cloud lingered around the coast on May 14 and 15, before May 16 was a mostly cloudy and fresher day with highs of only 15C.
Although it was fairly fresh on May 17 and 18, with highs of 16C and overnight temperatures close to freezing in some spots, this signalled the start of high pressure.
As daytime temperatures slowly rose from 18C on May 19 to 23C on May 21 so did the night-time temperatures, which saw the back of any frosts.
With warmer temperatures, this then meant that thunderstorms developed, firstly in the afternoon on May 21 and then overnight on May 22 after a sunny day.
After a cooler day on May 23 with highs of 18C, then temperatures slowly rose that week with 20C on May 25 which caused another round of heavy showers to develop in the afternoon.
Another warm and mostly dry day on May 26 with highs near 24C lead to early thunderstorms in the west of the region in the morning of May 27 before further showery rain and thunderstorms developed across the region in the afternoon.
At the end of the month surface winds stayed north-easterly which meant mist and fog around the coast, but sunshine broke out during most afternoons which meant warmer temperatures.
Cloud thickened up on May 30 and 31 in the morning, however as early rain and thunderstorms cleared some afternoon sunshine developed, although highs only reached 19-20C in places.
This May was one of the warmest on record, mainly because of some very warm and humid nights.
