Okay, let’s talk about Barcelona in March. I actually went there a few years back around that time, kinda tacked it onto a work trip nearby.

My Own Trip Planning
So, I started looking into it, you know, checking the usual weather apps and websites. They all kinda said the same thing – “mild spring”. Sounded pretty good, right? I pictured sunny days, maybe a light jacket. I wasn’t expecting beach weather, obviously, but thought it’d be consistently pleasant.
What I Packed (and What I Should Have)
Based on that “mild” idea, I packed thinking layers, which was definitely the right move. Here’s roughly what went in my bag:
- A couple pairs of jeans/comfortable pants
- T-shirts and some long-sleeved tops
- One medium-weight sweater
- A light, packable waterproof jacket
- Comfortable walking shoes (this was super important!)
- Maybe one slightly nicer outfit, just in case.
Honestly, looking back, I maybe could’ve used another slightly warmer layer, like a fleece or a heavier sweater, especially for the evenings.
The Reality on the Ground
When I actually got there, “mild” was, well, variable. It wasn’t freezing cold, not at all. But it wasn’t consistently warm either. The biggest thing was the difference between sun and shade, and day and night.
Mornings started off pretty crisp. You definitely needed that jacket, maybe even the sweater underneath depending on the wind. Walking around early, grabbing coffee, it felt cool. Not uncomfortable, but you wouldn’t want to be just in a t-shirt.

Then, usually by late morning or midday, if the sun was out, things changed fast. It could get surprisingly warm! I remember sitting outside for lunch near the Gothic Quarter one day, and I had to take my jacket off. Felt really nice, almost like late spring back home. Those sunny spells were glorious.
But don’t let the sun fool you. The minute you stepped into the shade, or if a cloud bank rolled in (which happened a couple of times), the temperature dropped noticeably. And evenings? Yeah, once the sun went down, it got chilly again pretty quickly. That jacket was essential for wandering around after dinner or heading back to my place.
Rain and Wind?
I got pretty lucky, mostly sunshine during my stay. But I did have one afternoon with proper rain. Not just drizzle, but a decent shower that lasted an hour or two. My light waterproof jacket was a lifesaver then. It wasn’t a total washout day, but it definitely changed my plans from strolling Las Ramblas to ducking into a museum.
There was also a bit of wind on a couple of days, especially near the coast. Nothing crazy, but enough to make that cool air feel cooler.
Final Thoughts from My Experience
So, March in Barcelona? It’s a real mixed bag, but mostly decent if you’re prepared. Don’t expect summer, pack smart layers. Be ready for cool mornings and evenings, potentially lovely sunny afternoons, and the chance of some rain or wind. Comfortable shoes are non-negotiable because you’ll do a ton of walking.

Overall, I had a great time. The crowds weren’t too bad yet, and the city has a great vibe. Just needed that flexibility with clothing!
