Mild and changeable: Alcúdia on 21 September

Good morning from Alcúdia. If you grabbed your first coffee around 8:15 at the small kiosk on the Passeig de la Platja – yes, the one with the blue parasol – you would already have heard the seagulls, the gentle clatter of boat fittings in the harbor and noticed: today will be pleasant, much like Alcúdia on August 6: Warm, partly cloudy – a perfect day for the beach and the old town. Not hot, not cool, just that typical late-summer mix where sun and clouds alternate.

Temperatures during the day

The thermometers remain moderate: as a low we expect around 22.1 °C, with highs climbing during the day to about 28.2 °C. Specifically: the morning starts at about 23.7 °C, at midday we are close to 27.7 °C, in the afternoon it is about 26.4 °C and at night it falls to around 24.8 °C. These values are comparable to Late Summer in Alcúdia: Clear Sky and Mild Warmth on 15 September 2025. Weather you can leave the house without a jacket for, although evenings with a few degrees less are not to be ruled out.

How it feels

Perceived temperatures are slightly different: in the morning you feel about 24.1 °C, during the day it can feel up to 28.9 °C. In the afternoon it remains pleasant at around 26.4 °C, and at night around 25.4 °C. In short: warm enough for time on the beach but not oppressive; the sun still has strength – sunscreen is still recommended, see Skin Cancer Foundation sun protection tips.

Pressure, humidity and wind

Air pressure is around 1013 hPa, relative humidity around 59 %. The wind blows from north-northwest (about 345°) with an average speed of 4.4 m/s. Only light gusts are expected (up to about 4.3 m/s), so nothing that should upset sailors or cyclists – apart from the typical little headwind that makes pedaling along the bay a bit more interesting. For contrast with a day that featured a moderate northeast breeze, see A cloudy day in Alcúdia: mild late-summer temperatures on September 17.

What to do today

A perfect day for a walk through the old town at 10:00, when the alleys are not yet full and the market stalls are just being set up, similar to Alcúdia on September 19: Clouds, Sea Air and Walks Instead of Sunbathing. Later, a late lunch on a shady terrace is worthwhile – the cafés along the Carrer Major fill up around 16:00, and then you hear more than the clinking of cups: traders, tourists and the indestructible street dog who always hopes a bocadillo will fall to the ground.

For cyclists, a leisurely tour along the bay is recommended; the light NNW breeze provides pleasant cooling. Those who want to go to the beach will find warm but not oppressive hours – don’t forget water and sunscreen. If you plan to visit the market in the afternoon: a thin sweater in your backpack is a smart idea in case the clouds linger in front of the sun.

And if the clouds briefly soften the light: don’t be upset. Those moments often conjure the most beautiful light on the old walls and the pines on the outskirts. Enjoy the day in Alcúdia – with a coffee at the harbor, the smell of the sea in your nose and the faint rattle of bicycles on the paving.
