Summer clothing still makes sense

Expect weather that suits light, breathable clothes rather than an autumn wardrobe. Days reach 25°C on 74% of occasions, so warmth is a reasonable expectation, not just a possibility. Midday can still feel hot, especially in direct sunshine; plan shade breaks rather than assuming September will be cool enough for constant walking. Nights average 20.6°C, which should suit sitting outdoors, though a light layer is useful when temperatures dip. The sea is another reason to go: its September average of 25.3°C makes swimming a comfortable prospect for most people. This month suits travellers who want both time in the water and days out, without needing the strongest heat Palma can offer.

Allow for rain rather than expecting an entirely dry trip

The catch is that September is not reliably dry. About 7 days have measurable rain, so leave room to move outdoor plans around and bring a light waterproof. That does not mean writing off those days altogether, but it does mean a short stay could feel wetter than the monthly average suggests. There is still about 7.2 hours of sunshine within 12.2 hours of daylight, giving you scope to enjoy time outside without treating every daylight hour as sunny. Humidity averages 72%, so breathable clothing is a sensible choice. Go if warm weather matters more than guaranteed clear skies; be more cautious if rain would spoil the main purpose of your trip.
