Surrey is set to endure another “hot spell” with temperatures to reach the mid-30C in some parts of southern England by the end of next week. High pressure from the Atlantic will cause the mercury to rise once again, although the Met Office does not expect to see any temperature records being broken.
Charlwood briefly held the temperature record in July when the village sweltered in 39.1C heat. The record-breaking heatwave was the first time the UK exceeded 40C with Coningsby in Lincolnshire setting a new record high of 40.3C. It is not thought Surrey will reach anywhere near those figures next week, with 28C predicted in Guildford on Wednesday (August 10).
Met Office chief forecaster Steve Willington said: “We could see parts of the UK entering heatwave conditions if the above-average temperatures last for three days or more. Many areas of the UK, especially the south will witness temperatures several degrees higher than average, but these values are likely to be well below the record-breaking temperatures we saw in mid-July.
“As the high pressure builds there is very little meaningful rain in the forecast, especially in those areas in the south of England, which experienced very dry conditions last month. Elsewhere in the UK, such as in northern England, Scotland and Northern Ireland, rain-bearing weather fronts will make limited headway against the high pressure, bringing some rain to north-western parts of the UK.”
It comes amid fears Surrey could be hit with the hosepipe ban that is set to be enforced in neighbouring Kent, Sussex and Hampshire. July was the driest on record since 1935 in England with only 10.5mm of rain being provisionally recorded on average. Rebekah Sherwin is a deputy chief meteorologist with the Met Office. She has explained what is behind the potential hot spell of weather next week.
“The weather pattern bringing next week’s hot spell is different to the one responsible for last month’s record-breaking temperatures which saw already hot air being drawn up from southern Europe adding to our own home-grown heat,” she said. “This time, that is much less likely; instead, temperatures will build steadily within the lingering area of high pressure.
“There is some uncertainty about next week’s temperatures, although in early August sunshine in the UK doesn’t have the heating potential of mid-July as the sun is lower in the sky and the hours of daylight are marginally shorter. Both of these factors suggest that we’re very unlikely to see temperatures peak much above low to mid 30s. However, this would still be a hot spell of weather.”
It is not yet known how long the hot spell will last, but the Met Office predicts a return to more changeable conditions from about mid-August.
