Exact date 'Indian summer' will bring 18C highs to UK

An 'Indian summer' could bring balmy 18C temperatures to Britain. According to new forecasts, there will up to five days of unseasonably warm, dry weather.

The higher-than-average temperatures will turn weather maps orange, with the south and southeast of England likely to experience the warmest conditions, Jim Dale from British Weather Services told the Mirror.

He said: "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."

Some parts of the UK saw the mercury hit 17C again on Wednesday, significantly above the October daytime average of 12C. But despite plenty of warm weather during daylight hours, more chilly evenings are to be expected going into November, according to another forecaster.

James Madden, from Exacta Weather, said: "Further high pressure rises or significant high pressure rises are likely to continue during next week and into early November at the very least. 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.

"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)."
