Conditions at Cozumel in August
August: Micro Swell and Maximum Humidity
August remains firmly in the summer lull. The average swell height is 2ft (0.6m) with a 6.4s period, and the swell distribution skews heavily toward ESE (68.6%) and E (16.8%). A notable 25.7% of the wave rose sits in the 0-1.5ft (0-0.5m) micro range, so unless a hurricane is spinning somewhere in the Caribbean, you are chasing ankle-biters. The wind is a mixed bag: ENE (23.8%) and E (27.5%) share the top slots with ESE (23.1%), all of it pushing hard into the SE-facing shore. Ideal offshore winds remain rare at just 1%. Water temp peaks at 29.4°C, air temp averages 28.5°C, and rainfall is 0.16in/day (4.17mm/day). August also marks the start of the serious Caribbean hurricane window; a well-tracked tropical cyclone in the eastern Caribbean can deliver legitimate long-period ESE/SE swell, though usually at the cost of onshore winds and stormy chaos.
