Parts of the UK could swelter in 38C heat next month as an Iberian heatwave tracks northwards, according to weather maps showing the intense heat plume building over Spain and Portugal in late June.
The scorching temperatures would be significantly above seasonal averages and could approach record-breaking levels for early July. South-eastern England is expected to bear the brunt of the extreme heat, though other regions may also see a notable rise in temperatures.
The forecast comes after weeks of unsettled weather across Britain, with conditions swinging between sunshine and showers. Current long-range models show hot air accumulating over the Iberian Peninsula before moving towards the UK in the first week of July.
Temperatures of 38C would pose serious challenges for public health and infrastructure. Authorities typically issue heat health alerts during prolonged extreme heat, advising residents on staying safe and preventing dehydration and heatstroke. Vulnerable groups, including elderly people and young children, face the greatest risks.
The Met Office and other meteorological organisations will provide more definitive guidance as the period approaches, allowing the public and businesses to prepare. While long-range forecasts remain subject to change, the potential heatwave underscores the importance of monitoring official weather updates.
