..HEATWAVE WARNING NOW IN EFFECT UNTIL 9PM MONDAY 18TH AUGUST...
WHAT… For Wednesday, highs of 27° - 28°. For Thursday, highs of 26° - 27°. Friday and Saturday will see highs of 29° - 31, with highs of 27° - 28° Sunday and Monday.
WHERE… Entire forecast District. Highest temperatures expected across eastern and southern parts of the District, particularly through the Vale of Leadon and through the Severn Valley.
WHEN... High temperatures Wednesday, with slightly lower temperatures Thursday. Hot conditions return for Friday and the weekend.
IMPACTS… Consecutive days of heat can have cumulative effects on people and pets. Hot temperatures will increase the risk for heat-related illnesses to occur, particularly for those working or participating in outdoor activities. At risk groups include the elderly, the very young, and those on certain medications, as well as those who spend a large amount of time outdoors and exposed to the heat.
PRECAUTIONARY ACTIONS…
High temperatures can cause serious illness. Take action now to protect yourself and others:
• Avoid peak heat – Reschedule strenuous activity to early morning or late evening.
• Stay cool – Use air conditioning or shade whenever possible.
• Know the symptoms – Heat exhaustion: heavy sweating, weakness, dizziness, nausea. Heat stroke: confusion, rapid pulse, loss of consciousness. Heat stroke is a medical emergency – call 999 immediately.
• Dress smart – Wear light, loose-fitting clothing, a wide-brimmed hat, and apply high SPF sunscreen.
• Hydrate – Drink plenty of water and non-alcoholic, non-caffeinated fluids.
• Keep your home cool – Close curtains and windows during the day, especially on sun-facing sides. Open them when the air outside is cooler than inside.
•Vehicle safety – Never leave children or pets in parked vehicles. Check the backseat before you lock your car.
Beat the heat – stay safe, stay hydrated, and check on vulnerable neighbours, friends, and family.
ADDITIONAL DETAILS...
Heatwave conditions are now forecast to continue throughout this week, persist over the weekend, and extend into early next week. While Thursday may see slightly lower temperatures in some areas—potentially falling just short of official heatwave thresholds—the consistently high temperatures before and after mean the Heatwave Warning will remain in place. Although peak temperatures are not expected to exceed those recorded on Tuesday, conditions will still be notably hot. With no significant rainfall expected, the ongoing hot, dry weather will further increase:
• Wildfire risk, especially in grassland, heathland, and agricultural areas.
• Water stress in crops, gardens, and natural vegetation.
• Heat-related illness risks, such as dehydration, heat exhaustion, and heatstroke.
A Heatwave Warning means widespread temperatures of at least 27°C are expected to persist for at least 3 consecutive days.
The next update will be issued by 9pm, Wednesday 13th August.
