Conditions at Sero Beach in January
January: Monsoon Lull with Clean Lines
January is all about quality over quantity. The average swell is a modest 0.7m (2.3ft), but the period sits at 7.2s, meaning the waves that do arrive are punchy and rideable rather than limp and gutless. Dominated by SSE swell (38.6 percent) and backed by SE and S energy, the primary window at Sero Beach is from the south-southeast, with most waves in the 0.5-1m (1.6-3.3ft) groveler-to-fun range. A secondary W-WNW swell component can add some wrapping lines when it lines up with the monsoon flow.
Wind is January's strong suit. The offshore quadrant-N, WNW, NW and NNW-accounts for the majority of observations, led by NNW at 25.3 percent and NW at 21.6 percent, and the surf is ideal 50 percent of the time. This is peak wet-season weather, with warm air around 25.2°C, water temperature at 29.6°C and 6.86mm/day of rain, so plan for a mix of steamy onshore showers and clean offshore windows. Do not expect barrels, but expect lined-up, user-friendly waves.
