Mallorca is preparing for a spell of extreme heat. According to Aemet, a blocking pattern in the atmosphere will trap a very hot, dry air mass over the Balearics and much of Spain, with temperatures building from the weekend and peaking next week.
Why it is happening
A blocking pattern works like a lid, preventing cooler air from moving in and holding weather systems in place. At the same time, warm air arriving from the south pushes temperatures up quickly. Combined with strong summer sunshine, the result is a prolonged period of intense heat.
The forecast
- Friday and Saturday: temperatures begin to rise, with highs in the mid-30s.
- From Monday: the heat intensifies, with maximums of around 38°C across much of the island and up to 40°C inland.
- Nights: very warm, with little relief after sunset.
How long will it last?
The duration will depend on an area of low pressure to the west of the Iberian Peninsula. Current models suggest the intense heat could last for most of next week.
Fire risk
The combination of heat and dry conditions raises the risk of wildfires. If the low-pressure system triggers dry thunderstorms — storms with lightning but little rain — lightning could start fires in vulnerable areas.
- Never light fires or barbecues in the countryside.
- Don’t throw cigarette ends from cars or on the ground.
- Report any smoke or fire immediately on 112.
Staying safe
- Drink water regularly throughout the day.
- Wear light, loose clothing and a hat outdoors.
- Plan outdoor activities for early morning or late evening.
- Use sun cream of at least SPF 30 and reapply every two hours.
- Rest in shaded or air-conditioned places.
- Know the signs of heat illness — dizziness, headache, nausea — and seek help if needed.
- Check on older relatives and neighbours, who are most at risk, particularly during warm nights.
