Possible September heatwave
The Met Office's latest long-range forecast, from Saturday, August 29, to Saturday, September 12, says temperatures are "again likely to be above average overall". However, it highlighted that there is still limited confidence over the exact weather pattern.
The forecast for the last week of August says: "There is also a chance that deeper Atlantic lows could lead to periods of widespread rain and strong winds at times, while some outbreaks of thunderstorms are also possible."
