Conditions at Banzai in January
January: Midwinter Offshore Punch
January is one of the most reliable months at Banzai, with an average wave height around 3ft (0.9m) and an average wave period of 5.1s. Although the period is short, the direction does the work: SW swell accounts for 15.8%, WSW 13.2%, S 8.4%, and SSW 6.2%, placing the main energy in the ideal quadrant for this SSW-facing beach. The bulk of the waves fall in the 1.5-3.5ft (0.5-1m) class, with occasional 6.5-8ft (2-2.5m) sets during the strongest events. Wind is the key here - ideal offshore flow occurs 21% of the time, dominated by NNE (16.5%) and NE (14.1%). Those directions blow straight offshore and keep the lines reasonably clean even if the period is on the short side. Air temperatures average 9.9°C and water temp sits at 13.2°C, so a 5/4 wetsuit is the standard uniform. With 2.00mm/day of precipitation, the winter lows that drive the surf also bring rain; time your session between fronts.
