So, someone asked me the other day about the water temperature in Mallorca. And it kinda sent me down a rabbit hole, remembering my own little quests to figure this out before trips. It’s funny, you think it’d be straightforward, right? Sun’s out, must be warm. Well, not always, my friend.
My First Brush with Mallorca’s Water
I remember this one trip, years ago, maybe my first time to Mallorca. It was springtime, I think April. The weather felt amazing on land, sun was shining, everything looked postcard-perfect. I got to the beach, saw that beautiful clear water, and just went for it. Didn’t even think to, you know, test it.

Big mistake. Huge.
I tell you, I hit that water and it was like a thousand tiny needles pricking me all over. Freezing! Okay, maybe not literally freezing, but it felt like it to my sun-warmed skin. I was in and out of there so fast, probably looked like a startled cat. That’s when I learned: air temperature and sea temperature are two very different beasts, especially in those shoulder seasons.
The Great Temperature Hunt
After that chilly surprise, I got a bit more diligent. Before my next trip, I decided I’d actually check the water temperature. Sounds simple, eh? I just hopped on the internet, typed in “Mallorca water temperature.”
And bam! Information overload. Tons of sites. Some looked like they hadn’t been updated since the internet was invented. Others gave you a single temperature for the whole island. Now, Mallorca’s got a fair bit of coastline, so I was a bit skeptical. Is the water in a shallow bay the same temp as a deep, exposed bit of coast? Probably not.
It was a bit like trying to find a good recipe online. You get ten different versions, all claiming to be the best. Some sites were super technical, talking about sea currents and stuff I didn’t really care about. I just wanted to know: can I swim without turning into an icicle?
Figuring Out a System
So, I started to get a bit more savvy. I learned to look for a few things:
- Recent updates: I’d check if the site actually showed today’s date or at least something very recent.
- Specific locations: Better sites would give temperatures for different beaches or areas around Mallorca, not just one generic number.
- Consistency: I’d often check two or three different sources. If they were all saying roughly the same thing, I felt more confident.
It took a bit of poking around, but eventually, I found a couple of weather and marine forecast sites that seemed pretty reliable. They weren’t always the prettiest, mind you, but they had the data.

What I’ve Generally Found About Mallorca’s Water
Okay, so after all that, what’s the deal with the water in Mallorca? Well, here’s my non-scientific, experience-based summary:
Winter (say, December to February): Pretty nippy. We’re talking maybe 13-15°C. Definitely wetsuit weather if you’re determined. Most folks, myself included, are giving the sea a wide berth for swimming.
Spring (March to May): This is when it starts to creep up. March is still cold. April, like my first shocker, can be a real mixed bag – maybe 15-18°C. You’ll see some brave northern Europeans taking a dip. By May, it’s getting more inviting, often hitting the high teens or even touching 20°C towards the end of the month.
Summer (June to August): This is prime time! June sees it get lovely and warm, consistently above 20°C. July and August? Proper bathwater. Often 24-26°C, sometimes even a touch more in shallow, sheltered coves. You can stay in for ages. This is when I love it.
Autumn (September to November): September is usually fantastic. The water holds its summer heat really well, so it’s often still in the 23-25°C range. October starts to cool a bit, but the first half can still be really pleasant for swimming, maybe 20-22°C. By November, it’s definitely on the decline, heading back towards winter temps.
Why Bother?
You might think, why all this fuss? Just go and see for yourself! And sure, there’s an element of that. But knowing roughly what to expect helps me plan. Do I pack the light summer wetsuit just in case? Or is it just swim shorts and T-shirt weather all the way? It also manages expectations. If I know it’s going to be a bit “refreshing,” I’m prepared. If I know it’s going to be like a warm bath, I’m already dreaming about it.
So, that’s my little journey with Mallorca’s water temperatures. It started with a shock, led to some internet detective work, and now it’s just part of my pre-trip ritual. A little bit of checking goes a long way to making those beach days even better. Now, if you’ll excuse me, I think I need to plan another trip…
