A cloudy day in Alcúdia: mild late-summer temperatures on September 17

Clouds and mild air: a relaxed late-summer day in Alcúdia

Alcúdia begins September 17 under an overcast sky – no thunderstorms, no steady rain, more of a muted sky that invites the island to pause. Those looking for sun on the beach today might prefer a spot on the promenade or a café on the Plaça. The air is pleasant; the heat of high summer is gone, and the sea murmurs quietly in the background, as if to remind us that September has its own rhythm.

What does the thermometer say?

Temperatures move within a comfortable range: around 23 °C in the morning and a daytime high of about 26.6–26.7 °C. In the afternoon values are usually around 25 °C, at night the mercury rarely falls below 24 °C. For late September quite normal — warm, but not oppressive, similar to the day described in Late Summer in Alcúdia: Clear Sky and Mild Warmth on 15 September 2025.

Feels-like temperature, air and wind

The felt temperature follows the actual progression: slightly above 23 °C in the morning, just under 27 °C during the day. Humidity is around 68 %, so it doesn't feel uncomfortably muggy. The air pressure remains stable at around 1022 hPa, a sign that no weather antics are imminent. The wind comes gently from the northeast (about 26°) and blows moderately at around 3.5–4 m/s. Small gusts rustle through the palms — not strong enough to blow away sunbeds, but noticeable while strolling on the paseo.

Clouds, chance of rain and outlook

Cloud cover is about 78 %, but the forecast stays dry: no significant precipitation. That means for Alcúdia: walking the old town without an umbrella, a café on the Plaça, and even a later beach walk is possible as long as you keep an eye on isolated gusts. The clouds provide this mild, even lighting that makes photos of the old walls and the harbor appear especially soft, as described during an overcast interlude in Alcúdia on September 19: Clouds, Sea Air and Walks Instead of Sunbathing.

Practical tip: If you head to the coast in the evening, bring a light jacket. The temperature drops only slightly, but the northeast wind can feel cooler when the sun slips behind the clouds. For walkers, closed shoes may be more comfortable than sandals — the pebbles at some beach sections feel fresher today.

What this means for island life

Days like these have their charm: less tourist noise, relaxed cafés, the Plaça filled with conversation and the occasional clinking of cups. Cyclists take advantage of the moderate temperatures for short tours along the coast, and the traditional siesta regains a quiet, cozy pace. The fishing boats glide out of the harbor leisurely; the sounds of engines and gulls mix with the soft wind.

And for anyone wondering whether this is the start of a cool autumn: not yet. These interludes are part of September — mild days that still keep us outdoors without making us sweat or shiver, a pattern also reflected in later summaries such as Mild and changeable: Alcúdia on 21 September 2025. A quick glance at the sky is enough to know: it stays pleasant.

All in all: a calm, slightly grey but pleasant late-summer day in Alcúdia. Ideal for exploring the old town, taking a break at a café or stretching your legs by the water in the evening — with a light jacket in your bag in case the wind freshens up.
