1. How rainy is May

If you're wondering how many days you'll need to dodge raindrops, the answer is: not too many.

On average, Barcelona gets about 5 to 7 days of rain in May.

That means most of the time, it's sunny or at least dry.

But the weather can be a little random.

Some years, it barely rains at all.

Other years?

Well, let's just say you'd want a good raincoat.

What's considered a rainy day can vary, too.

Some weather services count days with even a tiny bit of drizzle, while others only count it if it actually pours.

That's why the numbers sometimes feel all over the place.

You might see reports saying 4 days, others saying 10, and then a wild one mentioning up to 17 days (which is kind of rare).

So yeah, don't panic if you see different figures.

They're all looking at rain from slightly different angles.

But the average traveler experience?

You'll probably run into rain for about a week—or less.

2. May rain day numbers

Okay, here's a quick look at how different sources break down May's rainy days:

Source	Rainy Days in May	Notes
WorldWeatherOnline	6	Includes any measurable rain
WeatherAPI	6	Similar data as WorldWeatherOnline
Wikipedia (WMO data)	7 (≥0.1 mm)	Or 5 (≥1 mm)
BCN.travel	6	Averages based on past years
May 2024 (actual)	3	One of the driest recent Mays
Other reports	4 to 10	Depends on rain intensity criteria

Basically, if you're using historical data to plan, somewhere around 5-7 rainy days is a solid bet.

Anything beyond that is unusual but not impossible.

3. Year to year changes

Here's the thing about weather—it doesn't follow a strict calendar.

You might get a dry, beach-friendly May one year, and the next year it's all clouds and drizzle.

For example, in 2024, there were only 3 rainy days in the whole month.

Super dry.

But in other years, you might hit closer to 10, especially if there's a storm system moving through.

This kind of variation isn't just Barcelona—it's everywhere.

That's why weather apps and forecasts always come with that little "chance of" disclaimer.

Still, the long-term patterns do help.

May usually isn't a washout.

If it does rain, it's often short-lived.

4. What rain in May feels like

Rain in Barcelona during May isn't usually dramatic.

You're not dealing with Florida-style thunderstorms or endless grey skies.

Most rainy days are mild—like a few hours of drizzle or a cloudy afternoon with a passing shower.

And because temperatures are generally warm by then (think 17°C to 23°C or around 63°F to 73°F), it's not unpleasant.

Sometimes the rain even feels kind of welcome—it clears out the dust, cools the air, and makes the city smell fresh.

Locals don't really adjust their plans too much when it rains in May.

Just a light jacket, maybe an umbrella, and you're good to go.

5. When the rain shows up

There's no exact rule for when the rain comes in May, but if you're planning outdoor stuff, the beginning of the month can be a little wetter.

The later in May you go, the more likely you are to get sunny days.

Still, weather doesn't always follow trends.

You could hit a dry streak at the start or get a weird rain patch at the end.

Just check the weekly forecast before you fly and plan a few indoor activities—like checking out the Sagrada Família or Picasso Museum—just in case.

6. Planning around the rain

Even if it does rain while you're in Barcelona, it doesn't mean your day's ruined.

The city has tons of indoor stuff to do.

You've got cozy cafés, massive shopping streets like Passeig de Gràcia, and loads of museums.

Plus, since May isn't peak tourist season yet, rainy days mean even fewer crowds in the indoor spots.

Not bad, right?

And honestly, the kind of rain you get in May is easy to walk through.

You'll see locals just strolling like normal, not hiding under shelter or anything.

Here's a few rainy-day activity ideas:

• Visit the Barcelona Aquarium

• Go tapas hopping in El Born

• Wander through the Gothic Quarter under an umbrella

• Hit up the indoor Boqueria market for snacks

• Lounge at a chill bar with a view

7. What to pack just in case

So should you pack for rain?

Yeah, but don't go overboard.

You don't need heavy-duty gear.

A lightweight umbrella or a packable rain jacket will do the trick.

If you're trying to travel light, honestly, just bring stuff that dries fast and layer up if the temps drop a bit.

Your May packing checklist might include:

• Compact umbrella

• Thin waterproof jacket

• Shoes that can handle puddles (nothing crazy)

• A hoodie or light sweater for cooler mornings

Barcelona's vibe is super relaxed, so even if you get caught in the rain, it's not a big deal.

It just becomes part of the adventure.

So yeah, Barcelona in May isn't exactly monsoon season.

It's mostly dry, often sunny, and when it does rain, it's usually pretty chill.

Just a few drizzles here and there—not enough to mess up your trip.

With a bit of planning and the right mindset, you'll be just fine, rain or shine.

So pack light, toss in an umbrella, and get ready to enjoy one of Europe's coolest cities without stressing too much about the weather.
