Port d'Andratx: Mild and Partly Cloudy on September 20, 2025

Weather in Port d'Andratx for September 20, 2025

A sunny, partly cloudy Sunday is ahead, but don't panic: this is the pleasant, cozy autumn weather we like here. In the morning there's already warmth in the air, by noon the thermometer only rises slightly, and in the evening it stays mild. Perfect for a stroll along the harbor or sipping a cortado in one of the cafés on the Passeig.

Temperatures & Feel

The measurements speak for themselves: the low around 23.9°C, the high just under 26.3°C. The apparent temperature window is similar – around 24°C in the morning, around 26°C during the day. In short: no heat stress, but also no need for a jacket, except perhaps for sensitive night owls.

Wind, Humidity & Precipitation

A light wind blows from eastern directions (around 95°) with an average of about 4 m/s, gusts up to ~4.9 m/s. This creates exactly the small sea breeze you feel when anchoring or at the quay: it’s fresh, not bothersome. Humidity around 66%, air pressure 1020 hPa. Cloudiness about 75%, though rain is hardly expected – the chance of rain is practically 0%.

What that means in practice

If you plan to go out today: the conditions are relaxed. The light east wind makes the sea calm enough for relaxed boat tours, but if you go further out, of course keep an eye on wind conditions. On land it’s a day for strolling, shopping at the small market, or a late walk along the promenade as fishermen mend their nets and the sun peeks between the clouds.

My tip: bring a light cardigan for the evening – that’s plenty against the wind. And if the sky looks too gray: the colors of the sea still glow; with an espresso in hand everything looks better.

We’ll keep you posted if things change. But for now: go outside, take a breath, enjoy Port d'Andratx.
