Britain braces for hottest June day on record
The Met Office says wet bulb temperature will help assess humidity and heat stress as Britain faces a possible record June high.
The Met Office issued an extreme heat warning for parts of England and Wales on Monday and Tuesday, urging the public to stay #WeatherAware as temperatures reach dangerous levels.
Wet bulb readings serve as a fundamental tool for meteorologists assessing humidity and heat stress, measuring the lowest temperature achievable through evaporative cooling in the air.
When the dew point or wet bulb equals air temperature, relative humidity reaches 100 per cent, preventing evaporative cooling and significantly increasing heat-related illness risks for people and animals.
Modern weather stations now deploy capacitive sensors detecting voltage changes from water vapour, replacing traditional paired thermometers and delivering automated, more precise humidity measurements.
By monitoring wet bulb conditions, the Met Office continues delivering accurate forecasts supporting public safety in areas like Bradford as residents face warmer conditions ahead.
