Quick answer: Pack light. Cozumel is warm all year (about 24 to 32°C / 75 to 90°F), casual and easy to shop in, so you need less than you think. The essentials are your passport, some pesos and a no-foreign-fee card, two or three swimsuits, light breathable clothes, a hat, sunglasses, reef-safe mineral sunscreen (required in the marine park), a rash guard, water shoes, insect repellent, and sandals plus one pair of walking shoes. Add a light rain jacket from June to November and a light sweater for breezy evenings from December to February. Bring your own snorkel mask if you have one that fits, and any prescription medicine in its original packaging. Leave the heels, heavy jeans and expensive jewelry at home.
This is the list we'd give a friend coming to stay. It covers what you really need, what changes by season, what's worth bringing from home and what you can easily pick up on the island. Use it as a checklist; skip what doesn't fit your trip.

Documents and Money
- Passport: everyone flying into Mexico needs one, valid for the length of your stay. Cruise passengers should follow their cruise line's rules, but carrying a passport is wise in case you have to fly home from the island.
- Visitax: Quintana Roo charges international visitors a small tourist fee. Pay it online before you leave and save the QR code on your phone. Our guide to getting to Cozumel explains how.
- Cards: bring a credit card with no foreign transaction fee, and a debit card for ATMs. Tell your bank you're traveling.
- Cash: some pesos for taxis, tips, the marine park fee and small shops. Our money and tipping guide explains how to get them without bad exchange rates.
- Copies: a photo of your passport and insurance details on your phone, plus a paper copy in your bag.
- Driver's license: if you plan to rent a car or scooter. See our getting around guide.
- Dive card and logbook: if you're a certified diver.
What Clothes Should You Pack for Cozumel?
Think light, breathable and casual. Cotton, linen and quick-dry fabrics work best in the humidity. For a week, most people need:
- Two or three swimsuits, so one is always dry.
- A beach cover-up or sarong for walking to lunch from the beach.
- Shorts, light shirts, tank tops, sundresses or skirts for the day.
- One smarter outfit for a nice dinner. Even the best restaurants in Cozumel are relaxed: a sundress, or chinos and a collared or linen shirt, is plenty.
- A long-sleeved sun shirt or light layer for boat days and the sun.
- Sleepwear and underwear for the number of days, or plan to do a little laundry. Laundries in town wash by the kilo for very little.
Locals dress modestly in town and in churches, so cover up with a shirt and shorts or a dress when you leave the beach. Many restaurants ask you not to sit down in a wet swimsuit.
What to Pack for Each Season
| Season | Weather | Add to your bag |
|---|---|---|
| December to February | Warm days, cooler breezy evenings, occasional cold fronts (nortes) | Light sweater or jacket, long pants for evenings, a windbreaker for boat trips |
| March to May | Dry, sunny and hot; calm seas | Extra sunscreen, wide-brimmed hat, refillable water bottle |
| June to August | Hot and humid, afternoon showers | Light rain jacket, quick-dry clothes, strong insect repellent |
| September to November | Rainy season and the end of hurricane season | Rain jacket, an umbrella, waterproof bag, travel insurance |

Sun Protection and Reef-Safe Sunscreen
The sun in Cozumel is strong all year, even on cloudy days, and it's the number-one thing that spoils a vacation. Pack:
- Reef-safe mineral sunscreen with zinc oxide or titanium dioxide and no oxybenzone or octinoxate. Only biodegradable, reef-safe sunscreen is permitted in the Cozumel Reefs National Park, and many boats and parks check. Bring it from home; it costs more on the island.
- A rash guard or long-sleeved swim shirt for snorkeling. It protects your back without sunscreen and is the easiest way to avoid a burn.
- A hat and polarized sunglasses. Polarized lenses cut the glare on the water so you can see the reef from the boat.
- After-sun or aloe gel, just in case.
Shoes: What You Really Need
- Sandals or flip-flops for every day.
- Water shoes or reef shoes for the rocky entries at many west-coast snorkel spots and the ironshore on the east side.
- Comfortable walking shoes or light sneakers for town, San Gervasio and Punta Sur.
- Leave the heels at home. Sidewalks in town are uneven, and nobody dresses up that much.
Should You Bring Your Own Snorkel and Dive Gear?
Tours provide masks, snorkels, fins and life vests, so you don't have to bring anything. But a mask that fits your face makes a big difference, and it's light to pack. If you snorkel a lot, bring your own mask and snorkel, and add fins if you have room. Divers usually bring a mask, computer and sometimes a regulator, and rent the heavy gear (tanks, weights and often the BCD) from their dive shop. A waterproof phone pouch or small action camera is worth bringing for the reef and the turtles. Our snorkeling guide and diving guide explain what each tour includes.
Health and Toiletries
- Prescription medicine for your whole stay plus a few extra days, in its original packaging.
- Insect repellent, especially in the rainy season and at dusk. Mosquitoes and tiny biting sand flies (no-see-ums) are most active near mangroves and in the evening.
- Seasickness tablets if you'll be on a boat or the ferry. Take them before you board.
- A small first-aid kit: plasters, antiseptic cream, anti-itch cream, pain relief and something for an upset stomach.
- Rehydration salts for hot days or a stomach upset.
- Toiletries in travel sizes. Pharmacies in Cozumel are everywhere and well stocked, so you can buy anything you forget.
Tech and Gadgets
- Phone and charger. Mexico uses the same plugs (types A and B) and voltage (127V) as the US and Canada, so North American visitors don't need an adapter. Visitors from Europe and the UK need a plug adapter.
- A power bank for long beach and boat days.
- A small dry bag to keep your phone, cards and keys dry on boats.
- Check your phone plan. Many US and Canadian plans include Mexico, and free Wi-Fi is common in hotels, cafés and restaurants.
What to Pack for Kids
Add a kids' rash guard and a hat, a puddle jumper or swim vest, a small mask that fits, sand toys (or buy them on the island), favorite snacks for the flight, and any children's medicine. Our Cozumel with kids guide has a full family checklist and the best calm beaches for little swimmers.
What to Pack for a Cruise Day in Cozumel
- Your ship card and photo ID (you need both to reboard).
- Swimsuit worn under your clothes, a towel if the tour doesn't supply one, and a cover-up.
- Reef-safe sunscreen, a hat and sunglasses.
- Small bills in pesos or dollars for taxis, tips and the marine park fee.
- Your phone with the ship's all-aboard time and the port agent's number.
Our cruise port guide explains the three piers and how long it takes to get around.
What Should You Leave at Home?
- Heavy jeans, formal clothes and high heels.
- Expensive jewelry and anything you'd hate to lose.
- Chemical sunscreen with oxybenzone or octinoxate.
- Too many beach towels: hotels, rentals and beach clubs usually provide them.
- Drones, unless you've checked Mexico's rules and the restrictions near the airport and marine park.
What Can You Buy in Cozumel If You Forget Something?
Almost anything. Cozumel has large supermarkets, pharmacies on nearly every corner, and plenty of souvenir and beach shops downtown. You can easily buy sunscreen (though reef-safe brands cost more), hats, sarongs, flip-flops, snorkel sets, insect repellent, toiletries and medicine. Specialized items, like prescription medicine, a mask that fits perfectly, or electronics, are better brought from home.

Frequently Asked Questions
What should I pack for a week in Cozumel?
Your passport, cards and some pesos, two or three swimsuits, a cover-up, shorts and light tops, one smarter outfit for dinner, sandals, water shoes and walking shoes, a hat, sunglasses, reef-safe mineral sunscreen, a rash guard and insect repellent. Add a rain jacket from June to November or a light sweater from December to February.
Do I need reef-safe sunscreen in Cozumel?
Yes. Only biodegradable, reef-safe sunscreen is permitted in the Cozumel Reefs National Park, which covers most snorkel and dive sites, and many boats and parks check. Choose a mineral sunscreen with zinc oxide or titanium dioxide, and wear a rash guard to need less of it.
What do people wear in Cozumel at night?
Casual, light clothes. Shorts or light pants and a nice shirt, or a sundress, are fine almost everywhere, including the best restaurants. Bring a light sweater from December to February, when evenings can be breezy.
Do I need water shoes in Cozumel?
They're a good idea. Many west-coast snorkel spots have rocky entries, and the east side has sharp ironshore. Water shoes protect your feet and are easy to pack.
Should I bring my own snorkel gear to Cozumel?
Tours provide gear, so you don't have to. But a mask that fits your face makes snorkeling much more enjoyable, so bring your own mask and snorkel if you have them, and fins if you have room.
Do I need a plug adapter in Cozumel?
Not if you're from the US or Canada: Mexico uses the same type A and B plugs and similar voltage. Visitors from the UK and Europe need an adapter.
Can I buy sunscreen in Cozumel?
Yes, at pharmacies, supermarkets and beach shops, but reef-safe mineral sunscreen costs more on the island and the choice is smaller, so it's best to bring it from home.
Do I need a jacket in Cozumel?
Only a light one. From December to February a light sweater or windbreaker is useful for breezy evenings and boat trips. From June to November, pack a light rain jacket for showers.
Arrive and Unpack
The best trips start with a place to spread out. Casa Cascada, our three-bedroom home with a private pool, a garden and a rooftop deck, is an easy walk from snorkeling at the waterfront, so a swimsuit and sandals will get you most of the way. Book direct with no booking-site fees.
