Heatwave Safety in Monaco
Plan around the hottest hours, recognise when to slow down and know where to find official advice during periods of very high temperatures in the Principality.
Plan before the heat builds
Make the day shorter, cooler and easier
Monaco’s compact size can be deceptive: steep streets, steps and exposed waterfront routes can turn a short journey into sustained effort. During very hot weather, reduce the number of stops, use lifts or public transport where practical and reserve the middle of the day for a cool indoor break.
Carry water
Drink regularly throughout the day. Monaco’s official advice recommends at least 1.5 litres daily during very hot weather, unless a clinician has given you different guidance.
Plan a cool refuge
Spend two to three hours in a cool place. Identify a suitable public building, cinema, shop or other air-conditioned venue before setting out and confirm its current opening arrangements.
Do not wait for thirst or obvious distress
Heat can affect people before the warning signs feel serious. Start drinking, cooling down and reducing activity early. If you take medication, are pregnant or have a long-term health condition, ask a doctor or pharmacist for individual advice.
Extra care
Some people are more vulnerable to heat
Older people may regulate body temperature less effectively, while children and adults can lose substantial water through perspiration. Babies, young children, pregnant people and those with medical conditions or certain medications require particular attention.
Before going out
- Check the current forecast and any official Monaco safety message.
- Carry water, a hat and light, loose clothing.
- Choose one compact area instead of crossing the Principality repeatedly.
- Tell a companion or contact where you are going if you are vulnerable or travelling alone.
For babies and children
- Keep children under one out of direct sun.
- For older children, limit sun exposure and avoid the noon-to-16:00 period.
- Use a hat, protective clothing, suitable sunglasses and high-protection sunscreen.
- Offer fluids regularly and build frequent cool breaks into the day.
Official vigilance
Understand Monaco’s weather alert levels
Monaco’s legal weather-vigilance framework covers heat peaks and heatwaves. Government services may issue instructions, restrictions or exceptional protective measures according to the expected risk.
Yellow
A potentially risky weather event is possible. Review your plans and monitor official information.
Orange
A dangerous event is expected. Follow safety instructions and be ready for protective measures.
Red
A very dangerous event is expected and exceptional measures may apply. Follow official directions without delay.
Act early
What to do if someone feels unwell
Stop the activity, move to a cool place, begin cooling the person and alert someone nearby. For unusual symptoms, seek advice from a doctor or pharmacist. If someone needs urgent assistance, use Monaco’s emergency number.
For urgent assistance, call 112
Give a precise location, describe what has happened and follow the operator’s instructions. Monaco’s official numbering plan also lists 15 for urgent medical assistance and 18 for the Fire and Emergency Service.
