Mallorca swelters once more: Short heatwave brings late-summer warmth

Late summer ramps up again

Just as we've gotten used to the pleasant late-summer days, the sun moves in a little closer: from Sunday a short but intense warm-air phase will bring higher temperatures to Mallorca. You can feel it already in the morning — the air gets heavier, the cicadas sing louder and queues form again in front of the ice cream shops along the Passeig de Mallorca in El Born.

How hot will it be exactly?

Models show peak values of around 34 to 37 °C in some locations. It will be especially warm inland: up to 37 °C in Santa María del Camí, around 36 °C in Algaida and about 35 °C in Sóller and Pollença. Palma and Calvià are expected to be closer to 34 °C. Not a permanent climate — Last Heatwave – then the Turnaround: Changeable Weather on Mallorca — Wednesday and Thursday are forecast at 31–32 °C again — but enough to make you appreciate the siesta anew.

Wind, nights and an imminent change

A fresh westerly wind brings a breeze along the coast; during the day it can feel dry and oppressive, while evenings usually cool down to a pleasant 18–22 °C. That means hot afternoons and balmy evenings on the promenade. Aemet expects the warmth to last only a few days. By mid next week a weather change with slightly milder temperatures and isolated showers could reach us.

Sea temperatures: bathing season continues

The water is still inviting: measured values at the beginning of September were about 27.1 °C off Andratx and 26.6 °C off Pollença. Perfect for a late-afternoon dip — especially nice if you don't have to compete with an overcrowded beach, and similar to our note about a final sunny stretch in Short Late Summer: Saturday Will Be the Last Big Beach Day in Mallorca. For swimmers and stand-up paddlers this means warm water and less of a shock when getting in.

Everyday tips — a bit of neighborhood advice

This morning in El Born: children with ice cream, pensioners with newspapers and bus drivers taking shade breaks. My advice: avoid the hottest hours if possible; start garden or roof work early. Drink more than usual. And yes, it needs to be said: do not leave children or dogs in the car — not even for five minutes.

For beachgoers the classics apply: sun protection, shade breaks and enough water. A light hat, a hand fan or a thin cloth can work wonders. If you walk along the coast, the breeze on the Passeig de Born or at Cala Major makes the heat more bearable — as long as it doesn't bring sand with it.

What this means for daily life and the economy

Outdoor events could be moved to the cooler morning or evening hours, as described in Nearly 40 °C: Mallorca's Daily Life Under Heat Stress — How the Island Can Respond. Craftsmen and gardeners are better off starting early now, so tools aren't left in the heat. For the hospitality industry, hot afternoons often mean more terrace visitors in the evening — balmy nights are perfect for tapas and vermouth.

And a small advantage for agriculture: those with late-ripening grapes or crops may benefit briefly from the warmth — but only as long as no drought problems occur. A short heat window can help finish ripening without immediately endangering the harvest.

In short: From Sunday a short heatwave with peaks up to 37 °C, followed by somewhat milder days. The sea stays warm and invites you to swim. So: fill your water bottle, pack sun protection and learn to love the siesta again — the island has one last warm late-summer greeting for us.
