The contrasting start to Mays 1979 and 1990

    The first week of May 1979 was one of the coldest starts to May of the 20th century. A very cold arctic flow flooded the UK during the last day of April and this brought showers of hail and snow to many areas and extensive air frosts. Maxima were well below average for May often in single figures. There was a slow warm up but it wasn't until the 11th of May that the real warm up reached the far north of Scotland.

    By contrast, the first week of May 1990 was the hottest start to May during the 20th Century. With high pressure nearby and under brilliant sunshine, temperature soared to 25+C in many places even as far north as Scotland. RAF Lossiemouth recording 27.4C on the 1st, Rothes in Scotland 28.3C on the 2nd, 28.6C at Brabourne (Worcs) on the 3rd and 28.3C at Cheltenham on the 4th. All these values are record maxima for their respective dates. The weather did become cooler and unsettled by the 6th.

    Thank you as always...I can recall both spells: a snow flurry over the North Downs by Guildford in 1979 and 27c in Suffolk in 1990 (12 miles inland with dense haar on the coast).

    The contrast between early May 1990 and 1991 in East Anglia was dramatic: cold and wet with 7-8 maxima in places...

    Regards

    1979 was the last occasion I recorded lying snow at 0900 g.m.t in May; there was 2cm lying on the 1st.

    Prior to that it was the 18th in 1968.

    We've had lying snow in May in several years but it's unusual for it to last until 0900 g.m.t.

    May 1997 also got off to a very warm start 27C in London on 2nd and 26C on the next day. The general Election on 5th May that year is the 2nd warmest on record.

    The hottest General Election was in June 1970, which was the 2nd warmest June of the century. The date was 18 June 1970, Heath scored a surprise win over Wilson and it reached 31C in London.
