Being a tropical climate, Cozumel weather is warm and sunny with mild temperatures most of the time and humidity fluctuating throughout the year depending on the rainfall. Since weather conditions remain mild throughout the year without real extreme temperature fluctuations, this makes Cozumel an excellent vacation destination year round. The rains Cozumel experiences are warm, tropical rains which typically only last a few minutes and then the sun breaks out again without much interruption to daily activities.

If you are a scuba diver, you've heard it all before but diving the waters of Cozumel really is exceptional and breathtaking and the dives sites look different even if you return to the same spot in the same week. Variations in sea conditions as well as the weather will cause the reefs to appear different mainly because the amount of light that can penetrate to the depth of the reef varies. Clouds and rain will obscure sunlight so not much light will penetrate through the water to illuminate the reefs. But with the brilliant sunlight Cozumel enjoys most days of the year, the vibrant colors of the reefs come alive and provide quite a show for divers and snorkelers alike.

Since "insiders" live here on the island and dive and/or snorkel several times each week, this weather and sea conditions information is about as accurate as you will get with regard to dive conditions on an ongoing basis. Enjoy and come dive with us soon!

Any time is a good time to visit Cozumel ~ there are no really bad times of year weather-wise in Cozumel! That's the great thing about this island tropical setting ... it's never bad as compared to other places further north! But, with regard to dive conditions etc. here are a few guidelines to determine if you would be happy/comfortable diving during these time frames:
  • March - June: (Spring/Summer) Seas are usually flat, skies sunny ... alot of "no cloud" days, water temp 79-81 and viz from 100 - 300+ depending on if the island gets any rains. These months riding on the boat is pleasantly warm because humidity is less and alot of sunscreen is needed.

    July - October: (Rainy Season) Seas are usually flat, skies are more cloudy and rain comes/goes throughout the day with no real rhyme or reason so it's very humid [70%+] as well as warm. Water temp will be 80-84 and 300+ viz if the rains are scattered. This is also part of our hurricane/tropical storm time .... if these roll thru ~ all bets are off on water conditions obviously!! However, with that said this is also a great time to be here diving if there is no "weather"... Fewer divers, fewer people in general.

  • November -February: (Winter) Seas will be lightly choppy, most days it will be sunny with skies partly cloudy and water temps will go from 84 down to 78-80 range. Viz will be very good generally. During winter we get "nortes" that blow in from time to time and shut down diving for 2-3 days. Also, the boat rides can be chilly for sometimes there are low north winds and diving goes on.
These conditions only affect personal comfort so each person must decide what they are willing to tolerate what nature has to offer ~ As far as critters go ... they are here no matter what the weather although divers are more likely to see larger stuff during the winter months when the deep water is cooler ... especially the spotted eagle rays!

Just become a frequent visitor and you'll see that any day diving beats being somewhere else no matter the time of year!!

If you are visiting the Cozumel area you have to go on a Mayan Paradise Tour. Our Snuba and snorkelling adventure was the highlight of our week in Cozumel. We saw more fish and beautiful coral then we saw on our visit to the Great Barrier Reef. Our guides were terrific - very thorough, fun and energetic. Our trip back to the dock was a blast. We recommend this dventure to anyone vacationing the Cozumel area. Bryan and Jennifer ~ Ontario Canada

Just wanted to say I thoroughly enjoyed The SNUBA and snorkeling trip. It was absolutely breathtaking seeing the wonderful reefs and sea life firsthand. I would say the SNUBA experience made our vacation one of the best ever for us. I was as excited as a Young child in a candy store when I went under with your support staff. Your whole group was so helpful and accomodating to us and I loved the whole experience. Thanks again! We will definitely be back and also tell our friends about the wonders of SNUBA! G. Carlson ~ Houston, TX

The material presented was so much more than I would expect. Everything was explained clearly. The manner in which it was taught made the concepts easy to understand and follow. I learned a tremendous amount and I look forward to significantly improving my photographic efforts and experience. Fox Hill Underwater Photography Class Ryan Meglathery ~ Not Given
