It always says either rain or cloudy. It will probably rain for a hour or so in the afternoon but the rest of the day will be sunny. Get out early (from 9:00 - 2:00 PM ) to avoide the afternoon shower. Have fun!!
Check out this weather site instead of weather. com. It's more encouraging and we hear it's more accurate too. Forecast for Cancun International Airport, Mexico - HAMweather
Even the forecast we get on the TV here isn't accurate. It has rained maybe twice in the last three weeks. And it called for rain alot.
Just returned from Playa. It was on the cooler side so do yourself a favor and take a wrap/longsleeved shirt/sweatshirt if it gets cool. Rain...we had 1 and another 1/2 day of drizzle out of 8 days...not bad. Better to be prepared. Won't ruin your vacation if you are prepared. Not to worry, it will be warm, but possibly cool at night.
