Banbury and the rest of Oxfordshire will remain under an Amber extreme heat warning from the Met Office throughout Friday, as the exceptional June hot spell refuses to release its grip. The warning runs from midnight on 26 June until 11:59pm, keeping the region on alert for dangerously high temperatures and oppressive humidity.
Daytime highs are expected to widely exceed 30°C across the area, with some eastern and central parts of England possibly reaching around 38°C. Overnight relief will be scarce, as temperatures are unlikely to drop below the high teens, and built‑up areas may not fall below the low 20s. High humidity will accompany the warmth, with dew points forecast at about 22°C — far above the single‑figure readings recorded during the July 2022 heatwave — making it harder for the body to cool itself through sweating and raising the heat‑stress risk for everyone.
Cooler air is due to begin edging in from the west after Friday, but very warm conditions are likely to linger across eastern and southeastern England into Saturday, though not as intensely as earlier in the week. The UK has already provisionally set a new June maximum temperature record, with 36.1°C recorded at Gosport on 24 June, beating the previous mark of 35.6°C seen in both June 1976 and June 1957.
Met Office Chief Forecaster Matthew Lehnert described the heat as exceptional for June, noting that red warnings — already in force across much of southern and central England earlier this week — are reserved for the most severe events. The heat’s severity is underlined by the UK Health Security Agency, which has issued its own heat health alerts. Dr Agostinho Sousa, Head of Extreme Events and Health Protection at the agency, stressed that a red alert signals a risk to life even for healthy individuals, and urged people to stay hydrated, keep out of the sun during the hottest part of the day, keep homes cool, and check on elderly relatives, neighbours and those with underlying health conditions.
The Met Office began warning of this hot spell on 21 June, steadily raising the alert levels as forecast confidence grew. The red warning for Wednesday and Thursday covered most of southern and central England and Wales, with Friday’s amber extension keeping Banbury and Oxfordshire within the highest‑risk zone until the weekend’s gradual cooldown begins.
