Best time to visit Santa Maria: weather, sea, festivals and the summer boat

If you are deciding when to go to Santa Maria, you are mostly choosing between three windows. Mid-June to mid-September has the driest weather, lifeguards on the beaches and the island's two big music festivals. May and early October are quieter and still mild, but the beaches are unguarded and the rain is starting. November to March is for people who want the island to themselves and do not mind wind and wet days. For a first visit, aim for June or the first half of September.

Santa Maria is known as the sunny island of the Azores. It gets 2,000 to 2,200 hours of sunshine a year and is much drier than the other islands, with less than half the rain that falls on Flores. Temperatures stay mild all year. The long-term averages published for Vila do Porto, on the dry west side, look like this:

• June is the driest month, with about 22 mm of rain, and July gets about 25 mm.
• August is still dry at about 40 mm and has the warmest days, with an average high of about 25 °C.
• September brings about 57 mm, and October about 84 mm.
• November is the wettest month, with about 102 mm, and December and January each get about 95 to 100 mm.
• In January the average high is still about 17 °C, but there are only about 93 hours of sunshine in the month, against about 248 in July.

A second data set, from Climates to Travel, puts the numbers slightly differently (November at about 115 mm, June at about 20 mm) but agrees on the pattern. These are figures for the coast. The hills in the east, around Pico Alto (590 m), and the north-east coast are much wetter, with up to 1,800 mm a year in places, and they catch fog and wind. Winter is also the windy season. December's average wind speed is about 23 km/h, and wind makes a mild day feel cold, so pack a proper jacket from November to March.

The sea lags behind the air. It is coolest in February and March, at about 17.5 °C, and warmest in September, at about 23.5 °C. That makes September the best month for swimming, even though it is wetter than July and August. June water, at about 20.5 °C, is fine for a swim but feels cool after the first minutes.

You can swim on a calm day almost any time from June to October, but lifeguards only work during the official bathing season, which is set every spring. In 2026 it ran from 12 June to 13 September at Praia Formosa and Anjos, and from 15 June to 14 September at Maia and São Lourenço. All four bathing areas held a Blue Flag in 2026. Outside those dates the beaches are still there, but nobody is watching the water. Our guide to Santa Maria beaches covers each one.

Flights run all year. SATA Air Açores flies from Ponta Delgada on São Miguel in about 30 minutes, and Azores Airlines connects the island with Lisbon. In winter that is the only way in.

There is no regular Atlânticoline ferry to Santa Maria. In 2026 the only sea link was the Isabel C, a small cargo ship run by a private company, which carried up to 16 passengers between Ponta Delgada and Vila do Porto from 2 July to 1 October. The crossing took about 5 hours 20 minutes, and a one-way ticket cost 25 or 28 euros in 2026. Whether the boat runs, and when, is decided each year, so check before you plan around it. Our planning guide to Santa Maria has the details.

Most of the island's calendar falls between late spring and the end of August.

• The Festas do Espírito Santo (Holy Spirit festivals) take place around Pentecost and Trinity Sunday, so in May or June depending on the year. Each parish has its own customs, and the sopas, a bread and meat broth, are shared at communal meals.
• Santa Maria Blues brings international blues acts to Anjos on the north coast. The 22nd edition ran from 16 to 18 July 2026.
• 15 August is the feast of Nossa Senhora da Assunção, the island's patron, with a Mass and a procession through Vila do Porto that draws residents and islanders home from abroad for the summer.
• Maré de Agosto, a music festival held at Praia Formosa since the 1980s, follows a few days later. In 2026 it ran from 19 to 22 August, and a full pass cost 55 euros for non-members.

The second half of August is the busiest time on the island. Rooms and seats on the Ponta Delgada flights go early, and island guides suggest booking three to four months ahead for the festival dates. If you are not coming for the music, June or September gives you the same beaches with far fewer people.

Santa Maria is known for diving with devil rays and mantas. According to X-Ray Magazine, rays gather around the island regularly from June to October, with the peak from July to early September. If the rays are why you are coming, plan for those months. Our guide to diving at Santa Maria covers the sites.

• March and April: mild but still wet, about 79 and 55 mm, with short days and no lifeguards. Good for walking if you can wait out a rainy day.
• May: rain falls to about 30 mm and the Holy Spirit festivals may be under way. The sea is still cool at about 19 °C.
• June: the driest month, the bathing season opens in the middle of the month, and the island is quiet.
• July: dry and sunny, the summer boat starts, the rays arrive, and Santa Maria Blues fills Anjos in mid-month.
• August: the warmest month and the busiest, with the patron feast on the 15th and Maré de Agosto after it.
• September: the warmest sea, lifeguards until the middle of the month, and noticeably more rain than August.
• October: the summer boat stops on 1 October (2026), and the rain is back at about 84 mm.
• November to February: the wettest and windiest months, flights only, and an empty island.

What is the best month to visit Santa Maria? June or the first half of September. June is the driest month, and September has the warmest sea, both with lifeguards on duty and without the August crowds.

When is Santa Maria busiest? In the second half of August, when the patron feast on 15 August and the Maré de Agosto festival (19 to 22 August in 2026) fill the rooms and flights.

Can you swim on Santa Maria in October? On a calm day, yes, the sea is still about 22.5 °C. But the 2026 bathing season ended in mid-September, so there are no lifeguards.

Is Santa Maria worth visiting in winter? If you want quiet walks and do not mind rain and wind. Temperatures stay mild, about 17 °C by day in January, but November to January are the wettest months and you can only get there by plane.
