A rainy day in Vilamoura with kids: what actually works

It is raining, the boat trip is booked, and two children are sitting in the holiday flat. The question then is not what you can theoretically do in the Algarve in bad weather, but what is open today, how far away it is, and whether the money for the boat is gone. All three answers depend on the month.

How many rainy days this coast really has

The Portuguese weather service IPMA keeps the 1991 to 2020 normals for the Faro airport station, and they leave little room for doubt. July brings 0.9 mm of rain on an average of 0.2 days with at least one millimetre, August 3.0 mm on 0.2 days as well, June 5.1 mm on 0.8 days. Spend a fortnight here in high summer and you very probably will not see a single rainy day. Planning for rain in July or August is preparation thrown away.

The winter half of the year turns that around: December 90.0 mm on 7.0 days, November 75.5 mm on 6.6 days, October and January 6.0 days each. Across the year that adds up to 455 mm on just under 49 rainy days – dry by northern European standards, but not zero. Those seven wet days in December also rarely arrive one at a time; they come in as a front and then often two or three in a row. For a trip between November and February, plan exactly one well-thought-out backup day, no more.

Rain is not the problem – swell is

Drizzle tells you very little about the boat trip. What cancels departures is the sea. Marina de Vilamoura sits at the mouth of the Ribeira de Quarteira, and that is precisely where the area of the Capitania do Porto de Faro ends, which acts locally through the Delegação Marítima de Quarteira. In heavy swell the port authority closes the bar: during the storms of recent years, Vilamoura and Quarteira appeared alongside Albufeira, Alvor, Tavira and Vila Real de Santo António on the list of bars shut to all navigation. Nobody sails then, however obliging your operator may be.

Below that threshold, the type of boat decides. A catamaran with two hulls rides more steadily, an inflatable transmits every wave straight into your spine, a sailing boat heels. The same swell can therefore let a catamaran tour go ahead and sink a fast run out to the Benagil caves. The most sensitive of all is water sports: parasailing at €45 with ten minutes in the air, and jet skis, need calm water close to shore and are the first thing to be called off. Dolphin watching trips often still run, but the animals are harder to spot in churned-up water, because fins disappear between whitecaps.

What cancellation rules typically look like

The only binding text is the one on the booking page of your own trip – every operator sets its own terms, and nobody here can tell you what they are. The common pattern is free cancellation up to 24 hours before departure and nothing after that. If the operator calls off the trip because of the weather, it usually offers another date or a refund. The expensive case sits in between: you see rain in the morning, cancel yourself, and the boat sails anyway. The normal deadline applies, and you pay.

In practice that means two things. In the winter half of the year, do not book a boat trip for the last day of your holiday, but early enough for a replacement date to still fit into the trip. And when in doubt, ring the operator the evening before rather than deciding on your own: the skipper knows what the sea will look like at dawn. What minimum age children have to reach to come along appears in none of the descriptions in this catalogue and is a subject of its own – covered in boat trips with kids.

The one genuinely weatherproof option

The rock salt mine beneath Loulé is the answer that carries a wet day. €25 per person, 2 hours, 1,714 reviews at 4.8 stars – by review count the second most popular offer in the area. The cage takes about three minutes to go down, then you walk 1.3 km through galleries some 230 metres below the surface. Down there it is 23 to 24 °C all year, and the operator provides helmet, lamp and high-visibility vest. Loulé lies around 14 km north of Vilamoura, about a quarter of an hour by car.

On its own website the operator states that children under six cannot come down, and that six to twelve year olds must be accompanied by an adult; confirm that on the booking page before you book. It also states itself that there are no facilities for visitors with reduced mobility and that assistance dogs are not admitted – if that matters to you, clear it beforehand. And it remains a mine: dark, narrow, with no way out halfway through. A child who copes badly with confined spaces will be unhappy for two hours.

The parks, honestly sorted

Aqualand in Alcantarilha costs €23 and is shut precisely when you need it: the 2026 season runs from 10 June to 13 September. A water park is the worst rainy-day idea anyway. Zoomarine near Guia, €28.90, about 20 minutes by car, has the widest reach in the region with 3,965 reviews, but in 2026 it only opens from 12 March to 28 November and stays closed from December to February. It is largely an open-air park; whether all the shows run in the rain is worth checking on the park’s own site that morning.

Krazy World in Algoz, €15.95, roughly 30 minutes by car, is the only one of the three parks open all year, and it has covered parts: a reptile pavilion and an indoor play area. The rest, meaning pools with a slide, mini golf, pedal karts and a ropes course, lies in the open, and correspondingly less runs in winter. The go-kart experience at Karting Almancil Family Park at €14, some 10 km and eleven driving minutes away, takes place on outdoor tracks: slippery when wet and, depending on conditions, not running at all, so ring first. The Family Golf Park Vilamoura with its Roman-themed mini golf holes at €18.50 is right in town and still no use on a wet day – an open-air site, and its published opening hours only begin on 1 February.

Dry in town and nearby

Cerro da Vila on the western edge of the marina is half usable. The Roman villa itself, with mosaics, bath house and tanks for salting fish, lies under open sky; the museum beside it, with finds spanning 5,000 years, is indoors and open Monday to Friday from 9.30 to 12.30 and from 14.00 to 18.00. In steady rain that leaves you a good half hour of museum, no more. The rest of the town is gathered in the article on the sights.

The cinema at AlgarveShopping near Guia has nine screens and sits about 20 minutes away by car – on a wet afternoon the driving time decides between good and bad moods. And for the parents, expressly not for the children: the guided tour with wine tasting at Quinta da Tôr near Loulé, €18, 2 hours, 784 reviews, with a walk through the wine house, four wines, bread and the estate’s own olive oil. There is no children’s programme there, and no eight-year-old will sit through two hours of viticulture without a job to do. Further options on land are in things to do in Vilamoura, and what is worth doing with children on dry days is in Vilamoura with kids.
