Gentle Late-Summer Weather in Santanyí: A Day to Breathe

Gentle late-summer weather in Santanyí – sun, calm and still warm evenings

On September 15 Mallorca shows its well-measured side: already pleasant 23 °C in the morning, during the day values rise to just under 27 °C. On the Plaça Major a few cats lie lazily in the sun, the clinking of espresso cups can be heard from the corner café, and in the port of Portopetro people stroll along the quay in light clothing. This is what a Santanyí: Late Summer at Its Best feels like.

How it feels

The perceived temperature swings around 26 °C — ideal for sitting outside without a jacket. Even in the evening it stays pleasant, as described in Summer Evening in Santanyí: Gentle Breeze, Warm Streets and Market Scents on August 7, 2025: around 8:00 p.m. the thermometers still show about 24–25 °C. This is the kind of warmth you like to accompany with a glass of wine on the terrace. Between the calls of seagulls and the soft humming of boats everyday life quickly fades away.

Air, wind and outlook

The air with about 63 % humidity is rather dry than muggy, pressure is stable around 1021 hPa, according to AEMET weather forecasts. From the southeast comes a light breeze of about 4 m/s (occasionally gusts up to just under 5 m/s). That's enough to make the warmth bearable without blowing the sand off the beach. No cloud in the sky — the chance of precipitation is 0 %. Those heading to Cala Llombards or the small cove at Cala Santanyí today will have clear views of the sparkling sea and a calm day ahead; see Dry, warm and lightly cloudy: 8 September brings Santanyí late-summer temperatures.

What to do today

Make use of the mild afternoon hours: between 17:30 and 19:30 the sun is still warm but not oppressive — ideal for a walk along the promenade of Portopetro or a short detour to the Sunday market in Santanyí (if it's taking place), as noted in Mild Late-Summer Weather in Santanyí — a Cozy, Dry Thursday. Pack sunscreen, wear light shoes and maybe bring a thin jacket for the evening. Small, unobtrusive tip: the terrace of a bar in the old town is especially beautiful now when the last sun rays bathe the facades in warm light.

Why this is good for the island

Days like this are a balm for the local economy: cafés, small restaurants and boat renters can hope for guests who prefer to take things leisurely rather than rushed. At the same time the mild weather is easier on nature — fewer peaks in water demand, less heat stress for plants and animals. A calm late-summer day helps to make the shoulder season pleasant.

So: open the windows, let in fresh air, and enjoy the late summer. Whether beach, harbor or Plaça — today everything fits together. And if someone still has a heavy jacket with them: sometimes that is the best memory of a long day in Mallorca, which you later tell with a smile.
