Setúbal weather and best time to visit
The numbers below are long-term monthly averages for the Setúbal weather station (Estação de Fruticultura, IPMA station 770), for the period 1991 to 2020. They show what a typical month looks like. They are not a forecast and they do not promise sun on a given day, so check a forecast shortly before you travel.
In short, July and August are the warmest and driest months, while October to December bring the most rain. Late spring and early autumn sit in between. Which month is best depends on what you want to do, and the sections below match the season to the activity.

Best time to visit Setúbal by plan
Match the month to what you want to do.
Beaches
July and August have the highest highs and almost no rain, and June and September are close behind. The bathing season for the Arrábida beaches runs from 4 June to 15 September 2026. Outside that window you can still walk on the sand, but lifeguard cover is not assured. See the Setúbal beaches for summer access rules.
Walking in the Arrábida
Spring and autumn are cooler than summer. In May the average high is 24.2 °C with 53.8 mm of rain, and in September it is 28.1 °C with 31.2 mm. October is mild, but its rainfall of 99.2 mm is among the highest of the year. Walks suit those months better than the midsummer heat, and the Arrábida Natural Park page lists the trails and the convent visit.
City days
The old town, the market and the museums work in any month. In the wetter months from October to January, pick a day with a gap in the weather and keep the indoor stops, like the museum, for the showers. See the old town for hours.
Boat trips and the Tróia ferry
Boat trips and the ferry run in summer and in the cooler months, with different timetables. Check the operator's timetable for your date. The dolphin watching page has the rules for sightings, and there is no promise of a sighting in any month.
What to pack
By season.
| Season | Typical weather | Pack |
|---|---|---|
| June to September | Highs of 27.9 to 30.7 °C, little rain | Sun hat, sunscreen, water, light clothes |
| April to May | Highs of 21.1 to 24.2 °C, 54 to 64 mm of rain | Light jacket, walking shoes |
| October to November | Highs of 23.8 and 18.8 °C, wet months | Rain jacket, a layer for evenings |
| December to March | Highs of 15.5 to 19.5 °C, lows of 5.2 to 7.6 °C | Warm layers, a rain jacket |
For most visitors who want warmth without the peak heat, late May and September are a sensible compromise. The weather is a guide to the typical month, not a guarantee. Check a forecast a few days before you travel, and read how to get to Setúbal when you plan the route.
