December: Winter Peak Size, Onshore Battle
December delivers the second-largest average swell of the year at 1.2m (3.9ft) with a 9.9s period, as the northeast monsoon reaches full throttle. The wave rose shows NE 39.5 percent, ENE 52.4 percent, and NNE 5.8 percent, with a meaningful share of 1.5-2m and larger sets - this is the season's true building block. Lanuza will see solid 3-6ft (0.9-1.8m) surf and the occasional bigger pulse. However, the same monsoon winds are a constant challenge: N, NNE, NE and NNW flow is strong, and ideal winds are only 23 percent of the time. The best sessions are likely in the early morning, lighter-wind windows or when a brief S or SW flow aligns with the incoming NE energy. With air temps at 26.1°C, water temp 28.4°C, and precipitation rising to 13.91mm/day, December is a classic tropical winter surf month: warm, wet, powerful and inconsistent.
