Heat health alert issued for the South West

The amber heat health alert is in effect from 12PM on 27/06/2025 until 6PM on 01/07/2025 across the South West. The amber alert has a matrix score of 12. This means:

Significant impacts are likely across health and social care services due to the high temperatures, including:

• a rise in deaths, particularly among those aged 65 and over or with health conditions. There may also be impacts on younger age groups
• likely increased demand on all health and social care services
• internal temperatures in care settings (hospitals and care homes) may exceed the recommended threshold for clinical risk assessment
• the heat affecting the ability of the workforce to deliver services
• indoor environments overheating increasing the risk to vulnerable people living independently in community and care settings
• issues managing medicines
• staffing issues due to external factors (for example, affecting transport)
• increased demand for power exceeding capacity
• other sectors starting to observe impacts (for example, travel delays)

Overview of hot weather over the next 5 days

Southwesterly winds on Friday will draw warmer and more humid air across large parts of England, setting the stage for a notably warm weekend. While cloud and outbreaks of rain are expected to limit the warmth across northern and some western parts, the east and southeast are likely to see drier conditions and prolonged sunshine, allowing temperatures to exceed 27 degrees Celsius from Friday onwards. Southern coasts may stay cooler due to onshore breezes, low cloud or coastal mist. Temperatures are forecast to rise further on Saturday and Sunday, likely peaking on Monday. There remains a good chance of exceeding the medium threshold, especially across East and Southeast England where a peak value of 33-34°C could be observed. 30°C could also be reached in parts of the West and East Midlands and the Southwest. Nights will feel warm and humid too, with minimum temperatures widely staying above 16°C. Thunderstorms possible across central parts Monday before slightly fresher conditions are anticipated to return on Tuesday, as a band of cloud and showery rain sinks southeast, though confidence in the exact timing is low at this stage and the Southeast is likely to remain very warm.

Overview of hot weather over the next 6 to 15 days

High pressure out the the west in the Atlantic will likely allow a spell of mostly settled and warm weather to become established for a time. There remains the risk of outbreaks of showers at times, or perhaps weakening bands of rain arriving from the northwest. Temperatures are expected to be above average to start, but less-hot than the previous period. Changeable conditions may then become more likely toward the end of the period, with wetter and windier conditons across the north and west, but drier conditoons to the south and east. There remains a reasonable chance of Low impact threshold temperatures being breached later next week, most likely across central and southeastern regions.

Overview of hot weather over the next 16 to 30 days

Changeable conditions are more likely than settled conditions at first, especially across northern and western parts, and extending more widely across the UK at times. However, some drier and more settled spells remain possible, especially later in the period, these generally biased more towards the south and east. Some very warm spells are possible, the likelihood of these slightly higher than climatology, and most likely in the south or southeast.
