More places in England and Wales could exceed 30C, with some forecasts suggesting that temperatures close to the mid-30s could be possible in a few locations. Heatwave thresholds may also be briefly reached in parts of Scotland and Northern Ireland as humidity levels increase across the country.

Amber and yellow heat health alerts, external issued by the UK Health Security Agency (UKHSA) are in effect until 21:00 BST on 15 July. They warn that significant impacts are likely across health and social care services due to the high temperatures, including a rise in deaths, particularly among those with health conditions or aged 65 and older. Heat and humidity set to build againBrisk north-easterly winds and a spell of lower humidity, running around an area of high pressure in northern Scotland, have helped to break some of the recent intense heat, especially in central and eastern parts of the UK.

The Details

Temperatures across England and Wales on Monday will be lower than in recent days, but could still reach highs of 30C in some southern counties. For some locations, this means the run of consecutive 30-degree days will enter its second week. A few spots in Northern Ireland and western Scotland could also reach their heatwave threshold temperature of 25C.

By contrast, North Sea coasts will stay cooler at around 16C to 21C.

Temperatures will increase in most areas and are expected to peak on Thursday.

Readings around 26C or 27C are forecast across the western sides of Scotland and Northern Ireland. More of England and Wales will experience highs around the 30C mark, with some weather models predicting isolated peaks of 34 or 35C. The UK has already seen a record-breaking nine days this year where temperatures have reached 34C or higher, two more than the previous record years of 1976 and 2020.
