LONDON – The Met Office announced on July 9, 2026, that the United Kingdom has recorded eight days this year where temperatures reached or exceeded 34C, establishing a new record for the calendar year.
This frequency of extreme heat surpasses the previous annual records set in 1976 and 2020. While current temperatures are not expected to break any all-time daily records, the consistency of high-intensity heat across the first half of the year marks a significant meteorological shift and is being closely watched by government resilience planners and public health officials.
The record-breaking tally is distributed across three separate heat events:
- May: Two days at or above 34C
- June: Four days at or above 34C
- July: Two days at or above 34C (as of July 9)
A further reading of 34C or higher is anticipated for Friday, July 10. Under the UK’s national heatwave response framework, that would extend the period in which health services, local authorities and transport operators are expected to maintain enhanced readiness for heat-related disruption.
Regional June Temperature Peaks
The heatwave in June saw several regions hit historic markers, with East Anglia recording the highest temperatures in the country. Met Office forecasters say the distribution of the heat – concentrated in already dryer and more densely farmed regions – is likely to pose challenges for water management, agriculture and wildfire risk planning.
In Lingwood, Norfolk, temperatures peaked at 37.7C, significantly exceeding the previous June record of 35.6C. Other regional highlights from the June event include:
- Wales: Cardiff recorded 35.9C, the hottest June day in the nation’s history.
- Northern Ireland: Castlederg, County Tyrone, reached 30.8C, equalling its June record.
- Scotland: Threave, in Dumfries and Galloway, reached 31.2C, falling short of the all-time June record of 32.2C established in 1893.
Officials in devolved administrations have used the June figures to reiterate advice on workplace safety, school operations and care for vulnerable groups, stressing that heat thresholds for action can be lower in regions less accustomed to prolonged high temperatures.
July Heatwave Status
The current July heat event has already produced significant peaks. On Thursday, July 9, the highest temperature recorded was 35.5C at Wisley in Surrey.
Meteorologists are monitoring the duration of this spell, though current projections indicate that temperatures will drop slightly over the weekend. The Met Office, which operates as the UK’s national meteorological service under the umbrella of the Department for Science, Innovation and Technology, has maintained heat health alerts in coordination with public health agencies to help hospitals, care homes and emergency services anticipate demand.
Historical Comparisons and Absolute Records
The current trend has led to comparisons with the landmark heatwave of 1976. During that year, the UK experienced 16 consecutive days with temperatures above 30C. Current data suggests this specific record for consecutive heat is unlikely to be broken during the current spell.
The absolute highest temperature ever recorded in the UK remains the 40.3C reading from the unprecedented heatwave of 2022, which was registered in Coningsby, Lincolnshire. That event prompted a review of infrastructure resilience, with particular concern over rail lines, runways and energy networks designed for cooler historical norms.
Many areas are expected to maintain temperatures reaching official heatwave thresholds through much of the week beginning July 13. Local authorities are being urged to keep cooling centres, shaded public spaces and targeted communications in place as part of a broader adaptation push aligned with the UK’s statutory climate targets under the Climate Change Act 2008.
