If you’re checking the forecast for your trip to Galicia, you might be panicking at the sight of those little cloud icons. People call it the "urinal of Spain." It’s a bit of a running joke among Spaniards that if you head to the northwest, you’re going to get soaked. But honestly, the weather in Vigo Spain is one of the most misunderstood climates in the entire Mediterranean region.
It’s weird. You’ve got this city that officially records some of the highest rainfall totals in the country, yet it simultaneously enjoys a microclimate that feels nothing like the damp, grey stereotypes of the Atlantic coast.
The Microclimate Myth-Busting
Vigo sits in a "Ría"—a deep maritime inlet. This geography is everything. The surrounding mountains and the way the valley opens to the sea create a pocket of air that stays significantly warmer than the rest of Galicia. While cities like Santiago de Compostela are getting lashed by rain, Vigo is often sitting under a patch of blue sky.

It's basically a transition zone. Meteorologists categorize it somewhere between an Oceanic and a Mediterranean climate. You get the lush greenery of the north but the temperature profile of something much further south.
In August, the average high is about 77°F (25°C). That sounds mild, right? But with the humidity hovering around 76%, it feels substantial. You aren't going to melt like you would in Seville, where 104°F (40°C) is a standard Tuesday in July. Instead, you get this perfect "beach weather" that doesn't leave you gasping for an air conditioner.
When it rains, it actually pours
Let's talk about the elephant in the room: the rain.
Vigo doesn't do "drizzle" like London or Seattle. When it rains here, it’s dramatic. We’re talking about 67 inches (1,700 mm) of rain a year. For perspective, that’s almost double what London gets. But here’s the kicker—it falls on fewer days.
- December is the wettest month, averaging nearly 9.4 inches.
- July is the driest, often seeing less than an inch of rain.
- The city has about 129 rainy days a year, which is actually fewer than San Sebastián.
Basically, the winter is a wash, but the summer is surprisingly reliable. If you visit in July or August, your chances of a sunny day are actually quite high—around 80% sky clarity according to recent Peinador Airport data.

Seasonal Reality Check
Spring (March to May): This is the "gamble" season. You might get a week of 70°F (21°C) sunshine where the gorse and camellias are blooming everywhere, followed immediately by three days of Atlantic storms. It’s fresh. It’s vibrant. But pack a raincoat.
Summer (June to August): This is the sweet spot. The Atlantic breeze keeps the heat from becoming oppressive. The water in the Ría is still cold—seriously, it’ll take your breath away—but the air is perfect. It’s the only time of year when the Cíes Islands are truly accessible and enjoyable.
Autumn (September to November): September is a hidden gem. The crowds leave, but the warmth lingers. October is when the "weather in Vigo Spain" starts to turn moody. The humidity jumps back up to 84%, and the heavy Atlantic fronts start rolling in.
Winter (December to February): It’s rarely "freezing." Temperatures almost never drop below 42°F (5°C). It’s just... wet. The wind can be a bit of a beast, especially down by the port. But the city lights (Vigo is famous for its insane Christmas light display) make the rainy streets look pretty spectacular.
What to Actually Pack
Don't be that tourist who buys a flimsy 5-euro umbrella at a souvenir shop. The wind in Vigo will snap it in thirty seconds.

You need layers. Even in the height of summer, the temperature drops when the sun goes down over the Atlantic. A light jacket is mandatory for evening tapas. If you're coming in the "off-season," invest in a proper Gore-Tex shell. Boots are better than sneakers because when those Atlantic puddles form, they aren't messing around.
Actionable Advice for Your Trip
- Check the "Windy" app: Standard weather apps struggle with Vigo’s topography. Looking at wind models gives you a better idea of when a front is actually going to clear the mountains.
- Book Cíes Islands early: If the forecast looks clear for your dates, get your boat permit immediately. They limit visitors, and the permits vanish the moment the sun comes out.
- Go high for the views: When it’s partly cloudy, head to Monte do Castro. The way the light hits the Ría through the clouds is better than a perfectly clear day.
- Morning vs. Afternoon: In the summer, the mornings are often misty. Don't let it discourage you. Usually, that "brétema" (sea fog) burns off by 1:00 PM, revealing a scorching afternoon.
The weather in Vigo Spain isn't something to fear; it’s just something you have to respect. It’s the reason the seafood is the best in the world and the hills are so incredibly green. Just bring a rain shell and an appetite.
To make the most of your stay, always have a "Plan B" for indoor activities like the MARCO Museum or the El Corte Inglés top-floor cafe, which offers great views of the estuary even when it's pouring outside.
