The Met Office has issued a red weather warning for extreme heat in parts of south Wales. This is only the second time a red warning for heat has been introduced since 2021, which shows how serious the conditions are expected to be.
A red weather warning means the heat could be dangerous, with possible impacts on health, travel, and everyday life. Very high temperatures are expected both during the day and overnight.
Hot weather can affect anyone, but some people may be more vulnerable, including older people, babies and young children, and those with existing health conditions.
Here are some simple steps to help you stay safe and comfortable:
Keeping your home cool
- Keep curtains or blinds closed in rooms that get direct sunlight
- Open windows early in the morning or later in the evening when it’s cooler
- Keep windows closed during the hottest part of the day
- Open windows on opposite sides of your home to create airflow (if safe)
- Turn off electrical items when not in use, as they can generate heat
- Use fans if helpful, but remember to keep drinking fluids
Stay hydrated
- Drink plenty of water throughout the day
- Eat light meals such as fruit or salads
- Avoid too much alcohol or caffeine
- Wear loose, light-coloured clothing
- Take cool showers or baths to help lower your body temperature
Look after yourself and others
- Check in on older or more vulnerable neighbours, friends or family
- Keep children cool and out of direct sunlight
When outside
- Avoid the hottest hours (11am–3pm)
- Wear sunscreen, a hat, and light clothing
- Stay in the shade where possible and drink plenty of fluids
Know the signs
- Watch for dizziness, headaches, or nausea as these could be signs of heat exhaustion. If symptoms become severe, call 999.
