Overview of hot weather over the next 5 days

Temperatures are expected to peak Monday, becoming very warm and locally hot with widespread sunshine across the UK. Conditions will feel humid, with a warm night into Tuesday. The low-impact temperature threshold is likely to be breached widely across England. From Tuesday, temperatures will begin to cool from the west as outbreaks of rain and possibly thunderstorms move eastward. Despite this, it will likely remain warm or very warm in EM, EoE, London, and the SE, while noticeably cooler conditions develop in the west. By midweek, the weather is expected to turn increasingly unsettled, with temperatures returning closer to the seasonal average. However, it may still feel warm in eastern areas on Wednesday. The likelihood of breaching the low-impact temperature threshold will decrease significantly.

Overview of hot weather over the next 6 to 15 days

Unsettled conditions are generally expected, with showers or bands of rain likely to affect the UK at times throughout the period, accompanied by breezy weather. Temperatures are forecast to remain close to the seasonal average, reducing the likelihood of reaching the low-impact temperature threshold.

Overview of hot weather over the next 16 to 30 days

Although low pressure is expected to dominate at the start of September, there are indications that high pressure may build across southern parts of the UK by the second or third week. This could bring a spell of more settled weather, with temperatures potentially rising above the seasonal average in these areas. However, as we transition into meteorological autumn, it remains unlikely that the low-impact temperature threshold will be reached.
