The Best Time of Year to Go Boating in Galicia: Why September Is the Ría de Arousa's Secret Month

The same thing happens every year. September 1st arrives, half of Spain goes back to work, the beaches empty out… and we — who rent out our skippered boat from the port of Vilanova de Arousa — look at each other and say what we always say: now the good part begins. Because if you ask us when the best time to go boating in Galicia is, the honest answer isn't July or August. It's the month that has just started.

In this guide we'll walk you through how the Ría de Arousa behaves month by month, with no marketing spin, and explain why September is the best-kept secret of the Rías Baixas for renting a boat.

The Ría de Arousa isn't the open Atlantic: navigable almost all year round

The first thing to understand is geography. The Ría de Arousa is the largest of the Rías Baixas: an arm of the sea some 25 km long, sheltered from the open ocean by the Barbanza peninsula to the north, O Grove and A Lanzada to the south, and the Illa de Arousa and Sálvora island acting as a shield in between. That means protected waters: when there's a swell running outside, in here you cruise on calm seas.

That's why the mussel rafts (bateas) have sat anchored here for decades without a care, and why our real season doesn't run from June to August but from April to late October, with superb one-off outings even in winter when high pressure settles in.

The ría's year, month by month

Spring (April–June): the first outings

• April and May: days getting longer, the ría green and clean after winter, and almost nobody on the water. The sea is still cold for long swims, but for a cruise around the Illa de Arousa, the islet of Areoso or the Punta Cabalo lighthouse it's a beautiful time.
• June: swimming season begins and there are still no crowds. An excellent weather-to-tranquillity ratio.

Summer (July–August): peak season

Statistically the best weather — and also peak demand. Everything works: swimming, coves, paddleboarding, seafood in the bars of the Illa. In exchange, the most famous anchorages — Areoso first among them — fill up, and you need to book the boat well in advance. If August is your only option, come anyway: the ría is big, and our skipper knows which hours and which coves dodge the crowds.

September: the secret month (we'll explain below)

It deserves its own chapter, so keep reading.

Autumn and winter (October–March): the ría all to yourself

October often gifts week-long spells of Indian summer. From November to March, storms alternate with anticyclonic windows of cold sun and mirror-flat sea: days for photography, lighthouses and an utterly empty ría. It's not swimming season, but a half-day outing with warm clothes is a different, highly recommendable experience.

Why September wins: 6 reasons from people who sail here

1. The water is at its warmest of the whole year. The sea heats up slowly: after a full summer soaking up sun, the ría reaches its maximum temperature in September, higher than in June. You'll enjoy a swim more on September 10th than on June 20th.
2. The ría empties out. The anchorages of Areoso and the coves on the west side of the Illa de Arousa go from dozens of boats to three or four. You get back that feeling of discovering the place.
3. The weather is still summer weather. The "veranillo de San Miguel" — Galicia's Indian summer — is no myth: September strings together weeks of gentle north-easterly breeze and clear skies, more pleasant for boating than the August heat.
4. It's Albariño harvest month. The hillsides of Cambados, Meaño and the Salnés valley buzz with grape pickers. Combining a morning on the boat with a winery visit in the afternoon is the perfect Rías Baixas plan — and it only exists now.
5. Shellfish season kicks off. September opens the months "with an R": oysters, scallops, the raft-grown mussels you'll see from deck… it all gets better from here to Christmas.
6. Availability and flexibility. In August our calendar closes weeks ahead; in September we can adjust to the best-weather window of your week — which is how a day on a boat is really meant to be enjoyed.

What a September day on our boat looks like

We leave the port of Vilanova de Arousa, usually mid-morning before the thermal breeze picks up. We head for the Illa de Arousa threading between the mussel rafts — with a dolphin escort if you're lucky — then a long swim at the white sandbank of Areoso with the water at its yearly best, a quiet anchorage for lunch on board or at a bar on the Illa, and the return leg past the Punta Cabalo lighthouse in the golden afternoon light, which in September falls earlier and prettier. Those who fancy it round off the day ashore with a glass of new-vintage Albariño.

And if you like history: these waters are the route of the Traslatio, the maritime way by which, according to Jacobean tradition, the remains of the Apostle St James were carried up the ría towards Padrón. Sailing it in September, with no traffic, feels almost like it did back then.
