Fresh weather maps from the Met Office show temperatures peaking at 31C in London at 3pm on Monday, with Manchester reaching 29C and Cardiff 28C. The hot spell marks the return of heatwave conditions across the UK, and people have already been making the most of the sunshine, including those pictured enjoying Cannon Hill Park in Birmingham.
The Met Office forecast for Monday reads: "Rain affecting much of Scotland on Monday, some heavy. Scattered showers across Northern Ireland and other western areas, though most of England and Wales fine with some hot sunshine. Humid." That means the highest temperatures will be concentrated in the south and east, while western and northern areas see more unsettled conditions.
Four regions placed under amber heat health alert
The UK Health Security Agency (UKHSA) has responded by issuing four amber heat health alerts covering London, the East Midlands, East of England and the South East. These alerts come into force at 9am on Monday, August 3, and remain in place until 9am on Wednesday, August 5, making a 48-hour period of heightened risk.
According to the UKHSA, the rising temperatures are expected to place additional strain on health and social care services across these regions. The agency specifically warned that vulnerable individuals would be at risk, and that there could be an increase in fatalities, especially among people aged 65 and over or those with existing health conditions.
Health risks extend beyond heat exposure
The amber alert also draws attention to the danger of indoor environments becoming excessively hot. This is a particular concern for vulnerable people living independently in community and care settings, who may not have access to adequate cooling. The UKHSA further cautioned about the risk of water-related incidents, including cold-water shock and drowning, as people seek relief from the heat in rivers, lakes and the sea.
An amber alert is the second-highest level in the UKHSA's heat health warning system. It indicates that the expected impacts are likely to be felt across the whole health service, with potential for the whole population to be at risk. It also signals that other sectors, beyond health, may start to observe impacts and that a coordinated response is required.
Who should take extra care
- People aged 65 and over
- Those with existing health conditions
- Vulnerable people living alone or in care settings
- Anyone taking part in water-based activities
The UKHSA has highlighted these groups as being at greatest risk during the amber alert, particularly if indoor temperatures become too high or if they venture into cold water to cool down.
Met Office explains what an amber alert means
The Met Office clarified the significance of the alert in a statement: "An amber alert would represent a situation in which the expected impacts are likely to be felt across the whole health service, with potential for the whole population to be at risk and where other sectors apart from health may also start to observe impacts, indicating that a coordinated response is required."
It added that in some circumstances, a National Severe Weather Warning Service (NSWWS) Extreme Heat warning may be issued in conjunction with, and aligned to, the health alert. The Met Office noted: "This situation would indicate that significant impacts are expected across multiple sectors."
The forecast comes as much of England and Wales are expected to stay fine and dry on Monday, with hot sunshine and humid conditions. The rain affecting Scotland is expected to be heavy at times, while Northern Ireland and other western areas see scattered showers. For those in the alert areas, the advice is to stay hydrated, keep out of the sun during peak hours, and check on elderly neighbours and those with health conditions.
The coming days will require vigilance from both the public and health services, as the heat takes hold across the country.
