Weather: London to sizzle this May bank holiday weekend with 21C temperatures predicted

London will sizzle in 21C temperatures on Saturday as the capital enjoys a sunny May bank holiday weekend, the Met Office has said.

The forecaster has predicted temperatures will reach the low 20s on Saturday afternoon with bright sunshine expected throughout the day.

The good weather is expected to continue into Sunday with highs of 20C expected for the second day running.

But the Met Office has warned people to go and enjoy the sunshine while it lasts as there still could be thunderstorms on Sunday morning in the capital.

Heavy showers are predicted for 10am on Sunday morning, although no weather warnings are in place.

Temperatures are also expected to drop to around 17C in London on Bank Holiday Monday, according to the Met Office.

Met Office Deputy Chief Meteorologist Dan Harris said: “Sunday will have a mixture of sunny spells but also scattered, heavy and in places thundery downpours.

“Not everywhere will see them but where they do occur there is a small chance of some temporary issues such as flooded roads.

“Scotland will be cloudier with rain, while Northern Ireland will also be cloudy but with a chance that heavy showers could break out later too, bringing similar conditions to England and Wales.

“The outlook for Bank Holiday Monday is for brighter, cooler and breezier conditions with scattered showers for England and Wales at first, but a steady drying trend from the west is likely.”

He added: “The focus for heavier showers is expected to transfer to Scotland and possibly northeast England, where again these could be slow moving, the heaviest of which could cause some temporary, localised issues such as flooded roads.”
