Stable Autumn Weather in Palma on September 17, 2025

A Quiet Sky Over Palma

The 17th of September in Palma starts and ends with uncomplicated, almost cozy weather. A closed layer of clouds stays for the whole day, but rain is almost guaranteed not to happen – that is the key message for anyone planning to do something today. If you have coffee around 10 a.m. on Passeig del Born, you will not have to worry about a downpour, only wind-tousled hair.

Daily progression in numbers

In the morning the thermometer starts at about 22.05 °C. In the course of the afternoon the air rises to a maximum of 27.54 °C, before it returns to around 25.95 °C late afternoon. The night brings mild values around 23.96 °C – ideal if you want to stroll by the cathedral in the evening.

How the weather feels

Weather is not just numbers: subjective perception matters. In the morning it feels slightly warmer than the measurements (about 22.58 °C). By midday the perceived thermometer briefly climbs to 29.02 °C – enough to leave the jacket at home. In the afternoon and evening the feeling fluctuates around 25.95 °C and 24.55 °C, comfortable without sweating.

Air pressure, humidity and wind

Technical details for the curious: The air pressure is about 1022 hPa, humidity around 63%. The wind blows gently from the southwest (around 232°) at a speed of about 3.55 m/s. Gusts reach light values around 2.5 m/s – nothing that would whip away beach towels, but enough to make the clouds look restless.

My personal tip: If you wander through the Old Town today, take the quiet side street to Plaça Cort. The trees there protect from the cloud cover, and the cafés still have free tables. If you want to photograph, you get soft light – not dramatic, but very photogenic.

In short: A stable, quiet day in Palma – perfect for strolling, getting things done, or a late tapas evening in the La Lonja district. No dramatic weather changes, just a bit of Mallorcan laid-back attitude under a gray sky.
