Plan the day by the clock
In high temperatures, the 112 Illes Balears emergency service advises moving activities to the morning or late afternoon, when it is cooler. It also advises drinking plenty of water without waiting to feel thirsty, wearing light, pale clothing and a hat, and putting on sun cream at least half an hour before going out in the sun. Children should not play in the sun during the hottest hours, and nobody should be left in a closed car.
That gives a simple day plan:
- Early morning: a hike, a bike ride or a walk round town.
- Midday: shade, indoor spaces, short distances.
- Late afternoon and evening: swimming, a seafront stroll, dinner outdoors.
The sea as a way to cool off
The water is at its warmest in high summer: according to NOAA OISST, the open sea off the Bay of Palma averages 25.7 °C in July and 26.9 °C in August. It is measured by satellite offshore, not on the beach. Every month and coast is on the sea temperature page. Boat trips and kayaking fit well into the morning.
Hiking only in the early hours
The Serra de Tramuntana is no place for the middle of the day in high summer. The 112 advises checking the forecast beforehand, never setting off alone, leaving word of where you are going and when you plan to be back, and carrying enough water. The 112 also offers a walk tracking service: register the route and times in advance so the control room is prepared if something goes wrong. Lighting fires in the woods is banned. The coming days are on the forecast page.
