A pleasant late-summer day in Santanyí: sunny, only a few clouds, little rain — ideal conditions for a stroll along the harbor.
Short and Sweet: The Weather in Santanyí on September 21, 2025
Today, Santanyí is showing its mild side. The sky remains mostly blue, with only brief passing cloud patches. Perfect if you want to quickly visit the market at Plaça Major in the morning or enjoy a cup of coffee at the harbor.
Temperatures over the course of the day
The values start pleasantly: In the early morning the thermometers read about 24 °C. During the day it climbs to around 27 °C – warm but not muggy. In the afternoon it stays around 26 °C, and the night will be mild at about 25 °C. In short: No jacket needed, but a light sweater for the evening is practical.
How the warmth feels
Whoever is outdoors will notice little difference from the measured temperature. The apparent feel is around 24–25 °C in the morning, by midday it can feel warmer, up to around 29 °C in full sun. In the evening the warmth sensation drops a bit again – pleasant for sitting on the terrace.
Air pressure, humidity and wind
The air pressure remains in stable ranges at around 1013 hPa, which is quite uneventful. Humidity moves around 65%, noticeable but not uncomfortable. A steady wind from the southwest (about 225°) blows at around 4.5 m/s, gusts up to 5.6 m/s. For sailors and paragliders: good conditions, without getting wild.
Clouds and rain: What you need to know
The cloud cover remains light, estimated around 15–20%. The probability of rain is vanishingly small – practically 0% for the entire day. So: picnic, stroll, or simply an ice cream at the harbor — everything is possible.
I looked by the Passeig this morning around half past eight: a jogger, two dogs, and a fisherman checking his nets. Such small scenes say more than numbers. If you are planning for Sunday: Santanyí is a good option. Calm, friendly, with enough sun to recharge.
Stay hydrated and remember sunscreen if you stay outside longer. This was the brief weather update for Santanyí on September 21, 2025. Until next time — and enjoy the day!
