Conditions at Cozumel in July
July: Zero Percent Is Zero Percent
July is statistically the worst month for clean surf on the SE-facing side of Cozumel. Ideal offshore wind clocks in at 0%, the only month all year with a complete blank. Average swell height bottoms out at 2ft (0.6m), and 79.9% of all wave energy is concentrated in the ESE sector. Even the SE sector, normally the second-biggest swell source, shrinks to 8.2%. The period actually reaches its seasonal high of 6.8s, mostly a reflection of weak tropical swells pulsating through the Yucatan Channel, but the 1.5-3ft (0.5-1m) class dominates everything. Winds are firmly from E (34.5%), ENE (25.1%) and ESE (23.0%) at moderate-to-fresh speeds, which destroys what little shape the waves have. With water at 29.0°C, air at 28.3°C, and 0.12in/day (3.14mm/day) of rain, July is the true Caribbean summer: hot, sticky, small and blown-out.
