'Extreme heat' weather warning issued for Sheffield as temperature threatens to top 33C
A fifth heatwave of 2026 in England looms
An amber weather warning for extreme heat has been issued for Sheffield this week.
Temperatures are forecast to top 33C this Thursday (August 13) amid the fifth heatwave of 2026 in England.
The warning will be in force through much of Thursday and also covers parts of southern and eastern England, as well as parts of the Midlands.
The Met Office warns: “Following a warm night, a spell of very hot weather will affect England on Thursday. The highest temperatures will be in parts of the east, southeast and the Midlands, where 37 or even 38 Celsius could be reached. This may lead to impacts on transport, infrastructure and health.”
It comes after an amber heat health alert was also issued to Sheffield and nearly all of England for this week until 9pm on Friday, August 14.
The Met Office warns extreme heat is likely to adversely affect health from dehydration and heat exhaustion.
It poses other risks, such as more people visiting bodies of water which increases the risk of drownings.
Power cuts are also possible if heat-sensitive equipment breaks, as travel disruption - particularly on trains or Sheffield’s Supertram network - are also likely.
The Met Office said: "Very high temperatures may lead to impacts on Thursday.
"Adverse health effects are likely to be experienced by those vulnerable to extreme heat.
"The wider population is likely to experience some adverse health effects, including sunburn or heat exhaustion (dehydration, nausea, fatigue) and other heat-related illnesses.
"Some changes in working practices and daily routines likely to be required.
"Some heat-sensitive systems and equipment may fail, with the potential for some power cuts and the loss of other services to some homes and businesses.
"More people are likely to visit coastal areas, lakes and rivers, leading to an increased risk of water safety incidents.
"Some delays to road, rail and air travel are possible, with potential for welfare issues for those who experience prolonged delays."
