People are urged to take simple precautions to stay safe and reduce the risk of heat-related illness such as heat exhaustion and heatstroke.
South Central Ambulance Service (SCAS) said this will “avoid unnecessary 999 emergencies” and keep such services available for those who need it most.
It comes after a rare amber heat-health alert was issued by the UK Health Security Agency (UKHSA) for the south of England.
This will be in force until 9am on Monday, June 23.
Mark Ainsworth, executive director of operations at SCAS, said: “We want everyone to enjoy the warm weather safely, but high temperatures can be dangerous – particularly for older people, babies and young children, and those with long-term health conditions.
“Please help us by taking a few simple steps to avoid putting your health – and the health of others – at risk. Your actions really do make a difference.”

The trust said it typically sees a rise in emergency calls during extreme heat, many of which are preventable with a few sensible actions.
The following advice was issued:
- Stay hydrated – drink plenty of water and avoid alcohol or caffeine.
- Keep cool indoors – close curtains on rooms that face the sun and use fans if available.
- Avoid peak heat hours – stay out of the sun between 11am and 3pm.
- Check in on others – especially elderly or vulnerable neighbours, friends and family.
- Never leave anyone in a closed, parked vehicle – this includes pets and children.
A spokesperson for SCAS said: “If you or someone else begins to feel unwell with symptoms like dizziness, excessive sweating, or a sudden headache, move to a cool place, rehydrate, and seek advice from NHS 111 online or by phone.
“Always dial 999 in a life-threatening emergency.”
