The Met Office has indicated that more heatwaves could affect the UK next month, with temperature anomaly maps from the GFS weather model showing large areas of England and Wales shaded in dark red at the start of September. This suggests temperatures could rise above the seasonal average once more, following a 38C heatwave last week.
Forecast for September 2 to September 16
In its forecast for September 2 to September 16, the national weather agency said “unsettled” conditions look likely at first. However, it adds that “signals for the prevailing weather patterns affecting the UK soon become weak”, meaning something close to “the climatological norm” could develop, with a “northwest-southeast split in conditions” on the cards.
“The north and northwest will probably see the lion's share of the rain and any strong winds, whilst the south and southeast will probably see the driest and sunniest weather,” it says. Temperatures are expected to be a little above average overall, while “there is a chance that late season hot spells or heatwaves develop, especially in the south”. The UK has already seen five heatwaves this year.
BBC Weather outlook for September
Forecasters at BBC Weather say warm air could push towards the UK from Europe in September, with drier conditions more likely in the south. The BBC Weather forecast states: “The second week of September may see a high pressure building again across continental Europe, although timing any such transition is difficult at this stage. However, at some point this may push warmer air towards the UK, with temperatures ending up higher than the September average, highest across southern England. Conditions could become drier as well, but more likely across the southern UK than the north, where it may still be wetter than normal, especially across Scotland.”
