You can walk into the water without a hint of cold shock because it’s very warm and inviting. The average water temps are 71 degrees in December.
We went out on a snorkeling tour with a group of 12 other people. We spent the entire time in the water stopping at two reefs before anchoring at place where we got to see sting rays!
As your can see above the water is incredibly clear and comfy. The captain and instructor prepared fresh pico while we swam with insanely bright colored wish. My girlfriend even got scared they came so close!

What to wear in December
A few pudding ideas for a December in cozumel
The trick to packing for a trip to cozumel in December is to thin layers. I’m from the north so it always feels like spring to me, but if your from down south it with feel chilly. I focus on packing light layers for warm days and breezy nights. This is the exact list I packed myself
Daytime Essentials
- Swimwear (multiple)
- Light cotton t-shirts
- flip-flops
- Thin long sleeve
Sun Protection: Sunglasses are a must so interest in a good pair, and SPF 50 sunscreen.
Nighttime Essentials
- Comfy: light sweater or cardigan
- Formal Layer: Thicker button-down shirt
Remember, he nights can get breezy but it’s not for sure. It’s always better to have layers and not need them and be chilly. If your reading in town it will be much warmer than a romantic dinner by the water.
Crowds in December
This is considered the official start of peak season, meaning more crowds and higher prices, especially around the holidays. The high prices don’t stop people from booking their trips in anything more people come!
Downtown during peak time
Cozumel can get up to 7 cruise ships in one day, which means close to 40,000 people from ships alone. The island is festive, decorated for Christmas, with cultural events. I suggest you bring a light sweater for potentially breezy evenings or cooler ‘Norte’ winds that aren’t always the case but can happen.
