Summer may be almost over, but the UK could see a last-ditch mini-heatwave before the month is out. Parts of the country could be set for highs of 26C in a matter of days, as forecasts suggest an Indian Summer – an unseasonal spell of warm weather – is on its way. Maps from WXCharts show the mercury beginning to climb at around midday on Saturday, September 20, with south-eastern England benefiting most from the meteorological phenomenon.
While cities including London, Norwich and Oxford are set to swelter with temperatures in the mid-twenties by 6pm on September 20, not everywhere will be as lucky. Northern regions and some southwestern areas aren’t expected to record temperatures much above 20C, with the whole of Scotland hovering in the mid to low teens.
The hot weather won’t last long, and conditions are expected to peak on the evening of September 20, before gradually declining over the following days.
It could mark a welcome break from the wet and windy front set to batter parts of the UK earlier in the month, however, with a yellow weather warning in place across a stretch of western and southern England from Sunday, September 14.
The Met Office has also warned of an “unsettled” and drizzly first few weeks of September, followed by a trend of more “settled and dry” weather towards the end of the month.
“Temperatures will likely be close to average or slightly below overall, but if we start to see more in the way of dry weather later in the period, temperatures could recover back a little above average at times,” the forecaster said.
