Brits are in for a treat with a forecast of five days of warm 18C temperatures on the horizon. Weather maps are awash with orange, signalling higher-than-average temperatures set to sweep across the UK.

The country could be basking in an ‘Indian summer’ that’s predicted to last until the end of the month. Particularly in the south and southeast, residents can expect the warmest conditions, reports the Mirror.

Jim Dale from British Weather Services said he anticipates the mercury to soar to daytime highs of 18C, maintaining these pleasant levels for up to five days. He added: “An ‘Indian Summer’ may well be just around the corner, with a bias to the south and south of England. Watch this space. As soon as the 28th, we could see maximum temperatures around 18C, lasting four to five days.”

An ‘Indian summer’ is characterised by unusually warm, dry weather during autumn. This warm spell follows another day where temperatures reached 17C in parts of the UK on Wednesday, surpassing the typical October average of 12C.

Even northern Scotland, which has witnessed sporadic snowfall since autumn began, has seen mid-teen temperatures in the last day. Despite the daytime warmth provided by high pressure systems, forecasters warn of cooler evenings as we move into November, with a likelihood of frequent overnight frosts.

James Madden of Exacta Weather has forecasted: “Further high pressure rises or significant high pressure rises are likely to continue during next week and into early November at the very least, and despite some further mild to warm daytime temperatures for many for the time of the year from these types of developments in the coming weeks, it will also turn quite chilly to cold in the evenings, and overnight widespread frosts and foggy conditions are also to be expected for many despite these mild to warm temperature developments during the day from as early as this weekend and early next week (possibly patchy frost and fog at first).”
