Schools in parts of the UK are adjusting normal routines because of extreme temperatures, according to multiple reports. Some schools close early during the heatwave, while others keep operating but relax certain uniform requirements to reduce discomfort for pupils. The changes are presented as short-term measures intended to help children cope with very hot weather conditions. In addition to early closures, schools that remain open are reported to allow more flexible dress codes, such as easing restrictions on uniforms during the hottest periods. The specific measures vary by school or local area, but the overall approach is consistent across coverage: administrators respond to high temperatures with practical adjustments that may include earlier finishing times and modified uniform rules. The reports also indicate that not every school applies the same policy at the same time, reflecting local decision-making as forecasts and temperatures change. The measures are described as temporary responses to the heatwave.
