An amber warning was the first. When the red one arrived, the decisions spread like dominoes throughout Buckinghamshire in a matter of hours. Parents throughout the county were quietly rearranging their workdays, checking school websites, and refreshing emails by Wednesday morning. In Buckinghamshire, more than 125 schools and colleges had either completely closed or shortened the day. This wasn’t due to snow or a gas leak, but rather to the heat in the classrooms.
That fact makes me feel a little uneasy. For many years, Britain has constructed schools without air conditioning, believing that a truly hazardous summer day only occurred in other places. Every year, that assumption seems more dubious.
The Met Office issued a red weather warning on Wednesday from 9 a.m. to 9 p.m. on Thursday, which coincided with the times when kids would typically be seated at desks. In some areas of Buckinghamshire, temperatures were predicted to hit 35°C. Wednesday was the hottest June day in British history, with a temperature of 36.1°C in Hampshire. The heat wasn’t hypothetical. It was pressing up against single-glazed windows and sitting in hallways.

In its notice of closure, Cressex Community School specifically mentioned the red alert. In the words of Ickford School, “Classrooms too hot.” The obvious follow-up question is why air conditioning was installed if it can’t handle a red warning day. Ibstone CofE Primary School reported that their air conditioning just couldn’t keep temperatures at a safe level. These are not rhetorical grievances. These are the kinds of specifics that hint at a more in-depth discussion about infrastructure that no one is particularly interested in having at the moment.
Castlefield School and Waddesdon Village Primary both closed for two days in a row. St. Mary’s CofE Primary in Amersham went one step further and closed on Thursday and Friday, with a notice that regular hours will resume on Monday, the 29th. Some schools, such as Twyford C of E, adopted a more lenient stance, encouraging parents to keep their kids at home if possible while remaining officially open. Although it subtly transfers responsibility to families who might not have that flexibility, it’s a fair compromise.
Several schools, including Castlefield, set up remote learning, which is at least an indication that infrastructure from the pandemic era did not completely vanish. Depending on the school, the household, and the number of younger siblings who were also at home because their school was closed, the online lessons’ smoothness or chaos likely varied significantly.
It’s important to remember that Buckinghamshire wasn’t by itself. Oxfordshire reported about 90 partial closures, Somerset about 100, and Gloucestershire over 80. The failure wasn’t local. The disparity between how British schools were constructed and what the environment is increasingly demanding of them was addressed on a national level.
After reading the closure notices, there’s a persistent sense that this summer week won’t be the last one like it. Schools’ use of terms like “red warning,” “extreme heat,” and “safe temperature” is indicative of crisis management rather than a one-time annoyance. Parents were aware of that. The majority weren’t upset. Simply put, they were exhausted, juggling childcare on short notice, and thankful that the schools had been truthful.
As this develops throughout a county that is home to both leafy commuter villages and market towns, it is possible to observe two things at once: a structural issue that will be extremely difficult to ignore after a few more summers like this, as well as communities responding sensibly to an immediate problem.
