Sunday was the 34th day in 2026 when temperatures topped 30 degrees Celsius somewhere in Britain, matching the previous record set in 1995, per the Met Office and GB News’s confirmed reporting published this morning. The record-matching happened in early August. The summer has weeks remaining. The Met Office is now weighing whether to issue a rare amber or red extreme heat warning ahead of what forecasters expect to be Britain’s fifth heatwave of the year, with temperatures forecast to reach the mid-30s widely across England and Wales on Wednesday and Thursday. The country has matched its all-time record and the heat is still arriving.
A red extreme heat warning is the Met Office’s highest alert level for heat and is rare enough to require temperatures sustained long enough to pose a significant risk to life, particularly for the elderly and those with underlying health conditions. The current forecast is at the threshold where the Met Office is debating whether to issue one, which is either good news in that they are not certain it will be necessary or bad news in that they are considering it at all. Met Office meteorologist Tom Morgan said Monday: “We’ll probably see highs reaching the mid-30s quite widely on Wednesday, and indeed on Thursday too for England and Wales.” July was the driest on record for England and Wales since measurements began in 1836. That was last month.
Railway operators are separately concerned about whether track temperatures would require speed restrictions on Wednesday and Thursday, which is the operational consequence of rail infrastructure built for a different climate. Britain’s rail network was primarily constructed in the Victorian era, which was an era that had not anticipated mid-30s temperatures in August. The Met Office has been issuing heat warnings more frequently. The rail operators have been imposing speed restrictions more frequently. The government has been discussing climate adaptation more frequently. The infrastructure has been upgraded less frequently than any of those other things.
The record set in 1995 has been matched. Britain has had this many hot days before, in 1995, when the current consequences were different because the infrastructure was younger and the summers were less frequent in their extremity.
When Britain matches its all-time record for hot days before August is over and the Met Office is considering a red warning, what exactly is the country preparing for?
