UK Weather: Heatwave continues with amber heat health alerts UK weather: Yellow heat health alert extended for parts of England
(about 7 hours later)
An amber heat health alert remains place for parts of the UK until 1800 on Wednesday, as areas in England and Wales officially entered their fourth heatwave this summer. A yellow heat health alert has been extended for seven regions in England amid the country's fourth heatwave of the summer.
Temperatures will rise into the high 20Cs and low 30Cs, with parts of the East Midlands, Lincolnshire and Yorkshire experiencing the hottest weather with a maximum temperature of 33C forecast on Wednesday afternoon. Downgrading the alert from amber, the UK Health Security Agency said the areas covered until 18:00 BST on 18 August are Yorkshire and Humber, the East and West Midlands, London, the South East and South West and East of England.
Wednesday brings "a more complex picture", the Met Office has said, as high temperatures coincide with a chance of thunderstorms across northern areas. At the same time, a yellow thunderstorm warning is in place for large swathes of Scotland until midnight on Wednesday - this warning then extends to also cover Northern Ireland until 22:00 the following day.
A yellow weather warning for thunderstorms will be in place for some parts of Scotland between 14:00 and midnight. The Met Office has warned that some downpours could lead to some localised disruption, with road spray and potential flash flooding.
The weather warning, issued by the Met Office, covers northern, central and south-east Scotland, where showers are forecast. Conditions could be particularly heavy and thundery. These latest warnings come after England's most recent heatwave, with a top temperature of 33.4C recorded on Tuesday in Northolt, north-west London, Ross-on-Wye in Herefordshire and Benson in Oxfordshire.
The downpours could lead to some localised disruption, with road spray and flash flooding leading to difficult conditions. The highest temperatures in Wales, Scotland and Northern Ireland were 32.8C in Cardiff, 29.4C at Charterhall and 27.8C in Armagh.
There are further heavy and thundery showers expected across Scotland and Northern Ireland on Thursday, with an additional yellow weather warning in place from midnight on Wednesday until 22:00 on Thursday. While Scotland and Northern Ireland have not technically been in a heatwave, due to the three consecutive day rule, temperatures there are still well above the average for the time of year - reaching 29C in some areas on Wednesday.
While Scotland and Northern Ireland will not technically be in a heatwave, due to the three consecutive day rule, temperatures there are still well above the average for the time of year with a forecast of 25C to 29C on Wednesday. The storms forecast to hit both countries on Thursday are due to affect central and south-east Scotland in particular.
The threshold is 25C for most of the UK, but rises to 28C in London and its surrounding areas, where temperatures are typically higher.
Areas in south-west England, south-west Midlands, north-west England and East Anglia already met the heatwave criteria, by having three consecutive days above a certain temperature.

An amber heat health alert, issued by the UK Health Security Agency (UKHSA) and the Met Office, means the weather's impacts are likely to be felt across the health service. It is under these circumstances that we can see an increase in risk to health for individuals aged over 65, or those with pre-existing health conditions. A yellow heat health alert means the weather is only likely to affect those who are particularly vulnerable, for example the elderly, or those with existing health conditions.
Amber alerts are in place for London, the South East, East of England, West Midlands and East Midlands. A yellow heat health alert is in place for the South West, North East, North West and Yorkshire and the Humber. Heatwaves, like those experienced this summer in parts of the UK and Europe, have become more frequent and intense due to climate change, experts say.

Citing a 2023 report, the Pan-European Commission on Climate and Health said that heat-related mortality in Europe has increased by 30% in the past two decades, with more than 100,000 deaths recorded.Citing a 2023 report, the Pan-European Commission on Climate and Health said that heat-related mortality in Europe has increased by 30% in the past two decades, with more than 100,000 deaths recorded.
There is no current law in the UK for maximum workplace temperatures, although employers have an obligation to keep them at a comfortable level. The highest temperatures of 2025, so far, are:
Trade union Unite has called for the introduction of a maximum working temperature to be set at 30C and for work to be stopped where temperatures cannot be controlled indoors or when no protection - such as shaded areas - can be provided outdoors.
Overheating can lead to heat exhaustion or heatstroke. Heatstroke is considered to be a medical emergency that requires immediate treatment.
Older adults, young children and people with long-term health conditions are especially at risk.
