Do I Need a Wetsuit to Snorkel in Jacó?

Short answer: no — you do not need a wetsuit to snorkel in Jacó. The Pacific here is warm enough year-round that a wetsuit would just get in your way. Here's exactly what to wear so you're comfortable in the water on the best snorkeling Jaco beach has to offer.

Relaxed snorkeler floating comfortably without a wetsuit — Jaco Costa Rica best snorkeling at a warm cove near Playa Mantas — No wetsuit needed — the water's warm enough to just float and enjoy it.

Why no wetsuit?

Wetsuits exist to keep you warm in cold water. The ocean off Jacó simply isn't cold — it sits in the low-to-mid 80s Fahrenheit (around 27–30°C) all year, which feels bath-warm to most people. On a typical day of Jaco beach snorkeling you'll be perfectly comfortable in a swimsuit. A wetsuit would make you too warm, limit your movement, and add a layer you have to rent, fit, and peel off afterward — all for no real benefit.

What to wear instead

The goal in our warm water isn't warmth — it's sun protection and comfort. Here's the simple kit for Jaco Costa Rica best snorkeling:

A rashguard (swim shirt). This is the one upgrade we really recommend. While you float face-down, your back and shoulders take direct sun for an hour-plus. A rashguard covers exactly that area — far better than reapplying sunscreen.
A swimsuit or board shorts. That's genuinely all most guests need under the rashguard.
Reef-safe sunscreen for any exposed skin — neck, ears, backs of the legs.
Your mask, snorkel and fins — and those we provide, fitted for you, so there's nothing to buy.

Snorkelers with fins and swimwear ready for Jaco beach snorkeling — no wetsuit required on these tours snorkel Jaco trips — Swimsuit, fins, maybe a rashguard — that's the whole kit.

What about staying in a while?

Our tour runs about 1.5 hours in the water, and even then the warm Pacific means you won't get the chills the way you might snorkeling somewhere cooler. If you run cold or plan to float for a long time, a thin rashguard or a lightweight swim legging adds a touch of warmth without the bulk of a wetsuit. Kids especially tend to stay in happily without one.

Prefer to float, not swim? We have flotation vests available so you can relax at the surface and just look down at the reef. Between the warm water and a vest, Jaco beach snorkeling is about as easy and comfortable as it gets — no wetsuit, no struggle.

The bottom line

Leave the wetsuit at home. Pack a swimsuit, bring or buy a rashguard for the sun, add reef-safe sunscreen, and you're set for the best snorkeling Jaco beach offers. We handle the rest of the gear. We run three tours a day — 8am, 10am and noon — for $69 per person at a calm, white-sand cove about 25 minutes north of Jacó, with an in-water guide and photos included. It's one of the easiest, most comfortable tours snorkel Jaco visitors can book.
