Public Health Gibraltar
Heat Classification
The Gibraltar Health Authority works with the Met Office to monitor hot weather and provide colour-coded advice to help people understand the level of risk.
The higher the level, the more important it is to take action to stay cool, keep hydrated, avoid the strongest sun, and check on people who may be more vulnerable.
Green
Low risk
Normal summer conditions. Most people can continue with their usual activities, but it is still sensible to stay hydrated and avoid overexertion in the heat.
Yellow
Be aware
Temperatures may become uncomfortable for some people. Take extra care if you are older, pregnant, have a long-term condition, or are caring for babies or young children.
Amber
Take action
Hot weather may pose a risk to health, especially for vulnerable groups. Avoid the strongest sun, keep indoor spaces cool, drink water regularly and check on others.
Red
High risk
Extreme heat may present a serious risk to health. Follow public health advice, avoid unnecessary exposure to heat, and seek medical help if symptoms develop or worsen.
Who is most at risk?
Babies and children
Young children can become unwell more quickly in hot weather.
Older people
Older adults, especially those over 60, may be more affected by heat.
People with health conditions
People with heart, lung, kidney conditions, diabetes or other long-term illnesses may be at higher risk.
Outdoor workers and exercisers
People spending long periods outside may be more exposed to heat and sun.
What to do during hot weather
- Stay out of direct sun during the hottest part of the day where possible.
- Drink water regularly, even if you do not feel thirsty.
- Wear light, loose clothing, a hat and sunglasses outdoors.
- Keep curtains or blinds closed during the day to help keep rooms cooler.
- Check on older relatives, neighbours, young children and anyone living alone.
- Watch for signs of heat illness, including dizziness, nausea, headache, cramps, confusion or a rapid pulse.
When to get help
If symptoms persist or worsen, seek medical advice by calling 111.
If someone becomes unconscious or you think it is a medical emergency, call 999.
