Ever spot something washed up on the beach that looks like a shiny little balloon with tentacles? That’s not a sea toy—it’s a Portuguese Man o’ War, and trust us, it’s not the kind of Cuban souvenir you want to take home.
We saw this pop up in a Varadero group recently:
“Be aware that some Man of War have washed up on the beach this morning. We counted 8 while walking… Be careful folks!”
Yup. Eight of them. Not thousands, but enough to raise some eyebrows—and travel sandals.
First, let’s get the legal stuff out of the way…

So… Should You Be Worried?
Not unless you’re planning on hugging one. Which, please don’t.
One beachgoer chimed in with:
“8, that’s it. I am terrified of Medusa. Never been stung, probably should have been.”
Valid fear. While some travelers reported just a single sighting all week, others had stories of full-blown jellyfish takeovers:
“In December, there were about 5–10 every meter. From tiny ones to large ones.”
The truth? It’s all about the wind.
What Brings Them In?
It’s not a jellyfish conspiracy—it’s just weather. Portuguese Man o’ War tend to get blown ashore when strong north winds roll in. One traveler explained:
“They are usually pushed in from some strong north winds.”
Another confirmed that wind conditions were rough the day before. So, no need to panic—it’s Mother Nature doing her thing.
Are They Actually Dangerous?
Let’s just say: don’t poke one to find out.
These creatures can sting, even when washed up and seemingly lifeless. While most stings cause pain and swelling, some people may react more seriously. When a traveler asked, “Is it dangerous?” another replied:
“Oui, vaut mieux ne pas toucher ou marcher dessus.”
Translation: Don’t touch. Don’t step. Just admire from afar.
And for peace of mind, a seasoned beachgoer reassured:
“If it were a major invasion, the hotel staff would let you know.”
So keep calm and carry on tanning.
What Should You Do If You See One?
- Don’t touch it. Not with your hand, foot, or your beach selfie stick.
- Warn others nearby—especially kids.
- Watch your step when walking near the waterline.
- Got stung? Go straight to the lifeguard or hotel medical staff.
Also, heads up snorkelers: if there’s been wind and you see multiple jellyfish in the water, maybe swap snorkeling for a poolside mojito that day. You’ll still get the ocean vibe—without the sting.
And good news from a regular traveler:
“In May, there aren’t any.”
So if you’re heading to Varadero in late spring and summer, you’re probably in the clear.
