El Nido’s water is warm, so it is tempting to assume you need nothing more than swimwear. For a quick swim off the beach that is true. But spend several hours a day snorkeling on an island-hopping tour, or make three dives in a day, and even 28 °C water slowly pulls heat from your body. Add strong tropical sun, occasional jellyfish, sharp limestone and coral, and the question of what to wear in the water becomes surprisingly practical. This comparison breaks down the main options — shorty wetsuit, full wetsuit, thin skin suit and rash guard — and matches each one to the kind of trip you are planning.
This guide focuses on wetsuit choice specifically, for snorkelers, scuba divers and freedivers deciding whether to pack a shorty, a full suit, a skin suit or nothing more than a rash guard for El Nido.
How Warm Is the Water in El Nido?
Sea temperatures around Bacuit Bay typically range from about 26–27 °C during the coolest months (roughly December to February) up to 29–30 °C in the hot season from April to June. That is warm by any standard, but it is still several degrees below body temperature. Over a long snorkel or a 50-minute dive, especially with repeated immersion and wind on the boat between stops, many people start to feel chilled.
You may also hit thermoclines when diving: cooler layers of water at depth, which can feel noticeably colder than the surface. Cold sensitivity varies a lot between individuals. Slim travelers, children and anyone who gets cold easily at home will appreciate more coverage than a burly diver who runs hot. The basic physics of how wetsuits work — trapping a thin layer of water that your body warms — explains why even 2–3 mm makes a real difference.
Month by month. From December to February, northeast monsoon winds (amihan) cool the air and surface water slightly, and boat rides between snorkel stops can feel brisk, especially early in the morning. This is when cold-prone snorkelers most appreciate a shorty and divers commonly reach for a full 3 mm suit. March to June is the warmest stretch, with flat seas and water that can feel almost bath-like in sheltered lagoons; a rash guard or skin suit is all most snorkelers want, and many divers happily switch to shorties. From July to October, the southwest monsoon brings more rain, cloud cover and occasional rough seas. Water stays warm, but overcast days and wet, windy boat rides make an extra layer welcome.
Comparing the Options
The table below summarizes the trade-offs. In short: snorkelers mostly need sun and sting protection, divers mostly need warmth, and almost nobody needs a thick 5 mm suit in El Nido.
Quick decision guide by traveler type:
- Casual snorkeler on a day tour: Long-sleeve rash guard plus swim leggings or board shorts.
- Snorkeler who always feels cold: Shorty or a long-sleeve neoprene top over swimwear.
- New diver on a discovery dive or Open Water course: Whatever the dive shop provides, usually a 3 mm shorty or full suit; ask for the full suit if you chill easily.
- Experienced diver doing several days of diving: Full 3 mm suit, ideally your own for fit.
- Families with young kids: Children’s shorties or UV swimsuits that cover shoulders and back.
| Option | Thickness | Best for in El Nido | Pros | Cons |
|---|---|---|---|---|
| Rash guard + leggings | None (lycra) | Snorkeling tours, swimming | Sun and sting protection, packs tiny, dries fast | No warmth |
| Skin suit / dive skin | ~0.5 mm or lycra | Long snorkel days, warm-season diving | Full coverage, light, easy to travel with | Minimal insulation |
| Shorty wetsuit | 2–3 mm | Most recreational divers, cold-prone snorkelers | Warmth for the core, easy on/off | Arms and legs exposed to sun and stings |
| Full wetsuit | 3 mm | Multiple dives per day, Dec–Feb, cold-sensitive divers | Best warmth and protection | Bulky, hot on the boat, slower to dry |
| Full wetsuit | 5 mm | Rarely needed here | Very warm | Overkill for most people in El Nido |
Snorkelers: Rash Guard, Skin Suit or Shorty?
For island-hopping tours, the main threats are sunburn and stings, not cold. A long-sleeve rash guard with leggings or a full lycra skin suit protects your back, shoulders and the backs of your legs — the parts that face the sun while you float face-down for hours. It also reduces how much sunscreen you need, which matters for reef health. Our deep dive on rash guard vs sunscreen explains why many guides recommend covering up.
A shorty is worth considering if you tend to feel cold, are traveling in the cooler months, or will spend extended time in the water at places like the Small Lagoon or Secret Lagoon. Some snorkelers also like the gentle buoyancy of neoprene. The downside is that arms and legs stay exposed, so you will still need sun protection on those areas.

Scuba Divers: Shorty or Full 3 mm?
Most dive shops in El Nido rent 3 mm suits, often both shorties and full-length. For one or two dives on a warm April day, a shorty is perfectly comfortable for most people. For three dives a day, multi-day dive trips, night dives or the cooler months, a full 3 mm suit is the more common choice among experienced divers because warmth accumulates as a problem over repeated dives.
A full suit also protects against scrapes from rocks and accidental contact with fire coral or hydroids, which is relevant at sites with swim-throughs and overhangs. If you are booking night dives, the water feels colder in the dark, and full coverage is strongly recommended. Macro enthusiasts who spend long, still minutes watching critters (see our macro diving guide) also cool down faster than divers swimming continuously.
Agencies such as PADI teach that exposure protection should match water temperature, dive duration and personal comfort. When in doubt, choose the warmer option; you can always unzip on the surface.
Freedivers and Jellyfish Season
Freedivers usually prefer open-cell or smooth-skin suits for flexibility and warmth during long breath-hold sessions; 1.5–3 mm is typical for tropical training. If you plan a course, our freediving guide for beginners covers what local schools provide.
Jellyfish are present in Philippine waters, with sightings more common at certain times of year and after particular weather. A full-coverage suit, even a thin lycra one, is the simplest way to reduce stings. Read our jellyfish sting guide for what to do if you are stung.
Rent or Bring Your Own?
Renting is easy for divers: most El Nido dive centers include a wetsuit in the dive price or rent one cheaply. Fit and hygiene vary, so try sizes before departure day. Snorkel tours generally do not include wetsuits, though some operators rent shorties.
Bringing your own makes sense if you dive often, are an unusual size, or want a guaranteed clean fit. A skin suit or rash guard set weighs very little and is the best value item you can pack. A 3 mm full suit is bulkier, and El Nido flights have strict baggage limits, so weigh that against rental convenience.
Whatever you choose, rinse suits in fresh water after use and dry them in shade; strong sun degrades neoprene. Our general what to wear in El Nido guide covers the rest of your packing list.
Getting the fit right. A wetsuit only keeps you warm if it fits snugly without restricting breathing. Water should not pool at the lower back or flush in at the neck when you move. When renting, try on two sizes, raise your arms over your head and squat; if the shoulders pinch or the chest feels tight, go up a size. A suit that is too loose is little warmer than a rash guard. Women should ask whether the shop stocks women’s cuts, which fit the hips and chest better. Putting a suit on is easier if it is slightly wet, and a plastic bag over your foot helps it slide through the ankle.
Sun, Reef and Comfort Tips
- Cover up instead of slathering sunscreen. The NOAA guidance on sunscreen and coral reefs recommends protective clothing as the most reef-friendly sun protection.
- Bring a light layer for the boat. Wind on a wet body after snorkeling chills you more than the water did.
- Wear booties with open-heel fins if you are diving from beaches with rocky entries.
- Stay hydrated. Wearing neoprene in the sun between dives can overheat you quickly; keep the top half unzipped on the boat.
- Kids lose heat faster. A child’s shorty or skin suit keeps them in the water longer and happier.
Frequently Asked Questions
Do I need a wetsuit to snorkel in El Nido?
Not for warmth, usually. A rash guard or lycra skin suit for sun and sting protection is enough for most snorkelers; add a shorty if you get cold easily.
What wetsuit thickness is best for diving in El Nido?
A 3 mm suit suits most divers. Many choose a shorty in the hot months and a full 3 mm for multiple dives a day or December to February.
Is a 5 mm wetsuit necessary in El Nido?
Almost never. Water stays around 26–30 °C year-round, so 5 mm is overkill for nearly everyone.
Can I rent wetsuits in El Nido?
Yes. Dive centers rent or include 3 mm suits with dives. Snorkel tours rarely include wetsuits, though some operators rent them.
Does a wetsuit protect against jellyfish?
A full-coverage suit, even thin lycra, greatly reduces exposed skin and therefore stings, though it cannot protect your face and hands.
