Partly Cloudy and Mild: Sóller on September 21

Autumn sends its heralds, but late summer still clings to the bay of Sóller, as noted in Sóller on 4 September 2025: Cloudy, mild late-summer day to enjoy. On September 21 we can expect a relaxed mix of sun and clouds, little wind and temperatures that invite you outdoors — not too hot, not too cool. If you take a walk this morning at Port de Sóller, you can hear the gentle scraping of boats at the quay and the murmur of traders on the Calle de Sa Mar.

Temperatures During the Day

The morning starts mild: around 07:00 the values are about 21.3 °C. During the late morning the temperatures climb to up to 28.5 °C around 14:00–15:00 — enough warmth for an ice cream at the harbor, but not as oppressive as mid‑August; similar late‑summer warmth was reported in Cloudy, Warm, Relaxed: A Late-Summer Day in Sóller on 17 September 2025. By late afternoon the values drop moderately to around 25.8 °C, and at night the thermometer settles at a pleasant 22.9 °C. A light jacket for the evening is more than sufficient.

How the Weather Feels

The perceived temperatures are very close to the measured values. In the morning it feels just above 22 °C; when the sun breaks through the clouds, spots along the Passeig can feel briefly warmer. In the evening it’s mild enough to sit outside at one of the cafés — cups clinking, occasional guitar sounds drifting over the promenade, and waiters happy to welcome guests who prefer watching the sky to studying the menu.

Pressure, Humidity and Wind

Air pressure remains stable at about 1014 hPa, which feels calm, almost like the gentle rise and fall of the waves at the harbor mole. Humidity hovers around 55 % — pleasant, especially if you head into the Serra de Tramuntana and the pines smell of resin and sea. The wind is weak from the west (around 270°) with speeds of about 2–3 m/s; gusts are moderate, so a ferry crossing or a small sailing trip stays calm.

Cloud Cover and Precipitation

Cloud cover during the day is about 40–50%. There are frequent gaps through which the sun peeks; no rain is expected for the day. In the late afternoon denser cloud banks may form briefly — more a photo opportunity than a reason to cancel a picnic. The roads into the mountains are dry and visibility is good: ideal conditions for a short hike on well‑known Tramuntana paths, consistent with the report Sóller on September 25: Clouds but comfortable temperatures.

Tips for the Day

If you plan to visit a market: the stalls on the Calle de Sa Mar and the small weekly market tempt with fruit, cheese and handcrafted items. The morning is still quiet, vendors are setting out their goods, and the chats with locals are almost a regional ritual. For a short trip inland it’s best to set out early before the sun fully takes hold of the steep paths — and remember advice from a similar late‑September forecast Sóller on 27 September 2025: mild, cloudy — a late-summer day for strolling.

Why the Weather Feels Good

Such mild late‑summer days are typical for Mallorca during the seasonal transition — they give energy without tiring you out. For locals it means one more evening at the street café, a fish sandwich at the harbor, children playing with little sticks in the sand. For visitors: perfect conditions for photos, short hikes and relaxed time by the sea.

Conclusion: A calm, dry day with mild temperatures — ideal for market trips, walks at Port de Sóller or a short tour into the Tramuntana. Pack sunglasses and a light scarf, and nothing stands in the way of a cozy late summer.
