Conditions at Nalvo in January
January: The Monsoon Machine
January is the heart of the northeast monsoon. A strong Siberian high-pressure system pushes persistent NE-to-E winds across the Philippines, and Nalvo enjoys ideal surf wind 52 percent of the time. The swell window is dominated by N (33.8%), NNE (43.0%) and NNW (18.2%) energy, with most waves sitting in the 2-5ft (0.6-1.5m) range. This is punchy, average-period windswell at 7.7s rather than long-period groundswell, and true west-angle swell is rare. The cleanest, most consistent days happen when the NNW/NW component lines up with the offshore ENE-to-SE flow. With water temp at 25.6°C, air temps averaging 23.7°C and just 0.81mm/day of rain, January rewards early birds with glassy, rideable waves.
