What is the best weather site for predicting Cozumel conditions (other than sticking your hand out of the window of your condo)? Weather looks sporty on intellicast.com and weather.com on my visit June 1 - 6. Any thoughts?

A few tips:
  1. Delete your weather apps they are useless for Cozumel. They are never accurate for the entire island.
  2. Forecasts are not really to be relied on here. One part of the island can get no rain, the north may get rain every day for 8 days and centro can get just some showers. Some at night, some in the AM, some in the PM. Any combination or the reverse scenario can be true too.
  3. Don’t make your plans around what the weather forecast is - go with the flow and enjoy your vacation regardless of the weather - there's not a thing you can do about it. Make plans as you normally would then change if necessary - NOTE: Rain does not matter for diving - you're going to get wet.
  4. Cozumel is in the tropics - hence the term "tropical weather" (ie: tropical depression, tropical storm, tropical disturbance) - the word tropical is a descriptive word which refers to the geographic area - NOT the severity of a weather system.
  5. When the forecast says rain or even thunderstorms - that means that it may rain at some point during the day on some part of the island for some period of time - usually about an hour or less in the afternoon and then it's done
  6. Refer back to #1

I'll just add that it's a bit like deciding whether to take a medical test. What are you going to do if the test is positive? What are you going to do if the test is negative? If those two actions are the same, don't take the test. If what you see when you look at the Cozumel weather forecast won't change your plans, then don't look at the weather. Unless a hurricane is threatening, I never fret over the weather before a trip there.
 
I have always relied on Cozumel, Mexico Forecast | Weather Underground

Like Christi said it is not always accurate but over the years I have been able to see what the forecast and the actual conditions mean. This of course is not the same as what the port captain might see but that is whole other can of worms.
What you look for are North or west winds. If they are shifting West to North it could affect the diving. Thundershowers and rain are short lived and happen frequently. 10-20 min of rain and then it clears up again. So it doesn't effect the diving or really dampen your day very much. We dive and enjoy the outdoors 350 days a year in Cozumel. Consider that as you look at the weather forecasts.
 
Yesterday, after I saw this post, I checked what Accuweather was predicting. Since I'm going to be diving June 6-9, I was only looking at those days and (not really) alarmed when I saw that they were predicting 2.5" rain on 6/7 and 4.8" on 6/8. Of course, today, they are only predicting 0.26" and 0.78". By this afternoon, that prediction will probably change again. I expect it to rain, but there doesn't look to be any hurricane or tropical depression formation in the Atlantic right now, so I think we'll be good.
 
Its the tropics.......it can rainy every day or not at all. Their weather is not Jet Stream driven like the US and is almost impossible to predict.

The ONLY thing you can really rely on is sat imaging and radar to show storm systems forming and moving around. Beyond that, just get there and go with the flow. :)

My fav link to keep an eye on is:

When I planned my trip for May 5-16 I relied on Accuweather and Weatherunderground. I was shocked to see there was an 80 per cent chance of rain every day except one. It turned out that it rained for a couple of hours on Saturday the 12th. I have always thought that I would love to have a job where you never, ever have to be right. I think I've found it.

Who is to say they were not right?
An 80% chance of rain is still a 20% chance of no rain. (And it may have rained for a small amount of time on a part of the island you weren't at during those days.)

Our first trip it rained 100% of the days, for a few hours each day. And had 0 effect on our diving. It did make the snorkeling a bit cold on my back and legs though.
 
We had plans to meet a friend for lunch on Thursday. He couldn't make it because the streets where he lives (in the jungle behind the airport) were too flooded for his scooter. The roads were dry at our house. The last couple of weeks have been... drizzly.

This time of year, my assumption is that it's definitely going to rain at least some over a week. I've been wrong about that "definite" assumption sometimes. Rain rarely affects our plans apart from deciding whether to wear a rain jacket, wear the good shoes, or take an umbrella.
