Brits are set to bask in temperatures as high as 27C on Monday as forecasters predict a 700-mile “subtropical surge” is set to sweep across the country.
Met Office forecasters reckon the Indian Summer will continue with warmer than average temperatures set to stretch up until October 11. Those in the South can expect to enjoy highs nudging 27C with 24C in the North thanks to the hot south-westerly air flow.
Warm and muggy Monday
A Met Office forecaster said: “It's feeling warm, especially in the South, and it will stay warm and muggy on Monday.” Showers and gusty winds follow before the mid-20s return from the weekend for glorious spells stretching into October.
BBC Weather added: “September 21 to October 11 will be drier and warmer than average in many areas. High pressure will become more evident and bring above-average temperatures for late September and into October.”
Changeable but warm ahead
The Met Office added: “There's scope for rather warm days at times ahead. But it will be changeable, with rain or showers at times, most frequent across northern and western parts.”
The hottest year on record is expected as the Met Office said that - after the hottest summer recorded and one of the warmest springs - a warm autumn is twice as likely as normal, due to El Nino.
Odds slashed on record year
Bookmakers Coral slashed odds on 2026 beating 2025's record 10.10C UK average temperature from 2/1 to 1/2 odds-on. Coral spokesman John Hill said: “It looks like Britain's summer of sizzle is far from over. The forecast warm autumn makes the hottest year ever now odds-on.”
Met Office chiefs estimate the “chances of a warm autumn for the UK at one-and-a-half to two times higher than normal.” It comes as the strengthening El Nino event is set to become one of the strongest on record.
A forecaster added: “El Nino events are associated with warmer conditions across the UK in late autumn and early winter.”
