Is a UK heatwave in the weather forecast for September?

The Met Office released the new set of storm names for 2025/26 on Monday with Amy, Bram, Chandra and Dave the first four on the list.

Storms can be named by either the Met Office, Met Eireann or KMNI for impacts in the UK, Ireland or the Netherlands.

While a potentially deep area of low pressure is likely to bring wet and windy conditions on Wednesday, it should not be bad enough to be named Storm Amy just yet.

There is quite a lot of rainfall in the forecast this week and into the start of next and it will remain quite blustery with the potential for localised gales on Wednesday.

Temperatures this week will mostly be around the early September average of 17 to 22C but warmer air will move in from the near-continent over the weekend.

By Sunday, temperatures across England and Wales should get into the twenties with 25 or 26C possible in south-east England.

Some media reports are suggesting a heatwave or ‘Indian summer’ but temperatures are not expected to reach the official heatwave criteria.

While the term ‘Indian summer’ is sometimes used to describe a period of warm weather once traditional summer is over, its origin comes from warmer weather experienced later in the autumn – in October or November – after the first frosts.
