Adapting to extreme heat
Together, we can prepare our homes, streets and neighbourhoods to stay cool and safe.
How the Council's preparing
We're making long-term changes to help protect communities during extreme heat.
Some of the steps we are taking include:
- planting more trees to provide shade and cool local streets
- designing streets and public spaces to cope with hotter summers
- supporting green spaces and parks, which help cool built-up areas
- working to invest in schools and council buildings so they can still operate in high temperatures
- helping local health services support vulnerable residents during heatwaves
These changes also bring wider benefits. They make our neighbourhoods more pleasant, improve air quality and support wildlife.
What you can do at home
Small actions can make a big difference to how your home feels during hot weather:
keep blinds closed during the hottest part of the day. Use light-coloured curtains, blinds or material reflective on the outside
- stay out of the sun from 11am-3pm
- drink regularly, even if you do not feel thirsty – water and fruit juice are best
- take cool showers or baths and splash yourself with cool water
- wear loose, cool clothing and a hat when you do go outside
- open windows early in the morning and in the evening to let cooler air in
- use fans to help circulate air, and turn off unnecessary electrical devices that create heat
- plant trees or shrubs to provide natural shade and reduce indoor temperatures
- if possible, create shaded outdoor spaces to make gardens or balconies more comfortable
For vulnerable residents, keeping indoor temperatures down can help prevent heat-related illnesses. This includes older people, young children, and people with health conditions. Remember to check up on friends, relatives and neighbours who may be less able to look after themselves.
Support during heatwaves
The Council works with local partners to offer extra support during extreme heat. Community centres may be used as cooling spaces, and we provide guidance to care settings.
You can find practical advice on the NHS heatwave pages and sign up for Met Office weather alerts to stay informed.
Working together
Preparing for hotter summers is a shared effort. The Council is adapting buildings and streets, and communities are taking action in their homes and gardens. By planning now, we can keep Lewisham healthy, safe and comfortable in a changing climate.
