Cozumel Weather in January: What to Expect and Travel Tips

BySherry Arkfeld Updated

Are you planning a trip to Mexico and wondering about Cozumel weather in January? You’re in the right place.

I lived in Cozumel for nearly two years, so I’ve experienced every season. January is one of the best months to visit.

It’s in the dry season, so rain is minimal, the holiday crowds are gone, and the water is warm enough for long days of swimming or diving.

Here’s what you can expect if you’re visiting Cozumel in January.

Overview of Cozumel Weather in January

  • Average High Temperature: 83°F (28°C)
  • Average Low Temperature: 68°F (20°C)
  • Water Temperature: 79°F (26°C)
  • Rainfall: 2.4″ (6.1 cm)
  • Humidity: 77%

January is mild and comfortable, perfect for outdoor adventures or lazy beach days. Evenings are cooler, so you can enjoy outdoor dining without overheating.

Showers do happen, but they’re short-lived and usually just refresh the air.

What the Weather Really Feels Like

Cozumel in January is warm and welcoming. Days are filled with sunshine, and evenings cool off just enough for a sweater if you’re sensitive to breezes.

Humidity is there, but it’s far from oppressive. You can hike, bike, or explore without feeling weighed down by sticky heat.

When it rains, it’s usually a passing shower that cools things off. Last January, I found myself ducking into a café a couple of times when showers rolled through. It’s the perfect excuse to enjoy a good cup of local coffee.

What to Pack For a Trip to Cozumel in January

In addition to your usual things like shorts, t-shirts, and bathing suits, here are some things to bring with you to Cozumel:

  • Light Jacket or Sweater: You won’t need anything too heavy, but something to protect you from windy evenings or chilly mornings will be handy. I use this lightweight jacket that folds up into its own pouch. It doubles as sun protection.
  • Umbrella: Good to have all year. If you don’t need it for rain, you can use it for shade on hot days. I carry this small umbrella pretty much all the time.
  • Reusable Water Bottle: Cozumel’s water is not safe to drink. Take purified water with you in this reusable bottle that also keeps your water cold. I like it because the lid closes over the straw to keep it clean.

Things to Do in Cozumel in January

January is a great time to enjoy all of Cozumel’s outdoor activities. Here’s what you can look forward to:

  • Scuba Diving and Snorkeling: With the water temperature being quite pleasant, it’s a fantastic time for underwater adventures. There are even places you can snorkel right from shore.
  • Submarine Tours: Don’t want to get wet? See the ocean from inside a real submarine.
  • Mayan Ruins: The cooler January weather is perfect for exploring the island’s Mayan heritage, including the San Gervasio ruins, without the intense heat of the summer months.
  • Nature Parks: Visit eco-parks like Chankanaab or Punta Sur to enjoy nature trails, see exotic birds, and even catch a glimpse of crocodiles in their natural habitat.
  • Surfing Lessons: For the more adventurous, the breezier days of January are ideal for surfing.
  • Fishing: It’s a great time for deep-sea fishing, with the chance to catch species like sailfish and marlin.
  • Cultural Tours: Take a guided tour to learn about the local culture, history, and cuisine. January’s comfortable temperatures make it a prime time for excursions like tequila tours.
  • Swimming in a Cenote: For a unique experience, try swimming in a cenote, where the water is crystal clear and the formations are stunning.
  • Hiking: January is perfect for hiking in Cozumel since it’s not too hot. Don’t forget the insect repellent, as mosquitoes are plentiful year-round.

Safety Tips for January Travel

  • Travel Insurance: Always a smart idea. In January, delays often come from winter storms in the U.S. or Europe, not Cozumel. I use SafetyWing since it covers weather-related delays.
  • Hurricane Season: January is outside hurricane season, so big storms aren’t a concern.
  • Strong Currents: Be cautious swimming on the east side of the island where rip currents are common.
  • Windy Days: January can be breezy. Ports sometimes close to small boats when winds are strong.
