Conditions at Keramas in January
January: Peak Monsoon Magic
January sits squarely in Keramas' best window. The wind is ideal for surfing 64 percent of the time, and although the average swell height is only around 3ft (0.9m), the 12.5s average period means the SSW/SW groundswell is moving with real long-period power. Direction stats show a familiar wet-season pattern: SSW is the dominant swell direction at 48.7%, with SW next at 33%, WSW at 16.6% and a touch of W. The bulk of the energy is in the 2-3ft (0.5-1m) range, while roughly a quarter of all waves fall into the rippable 3-5ft (1-1.5m) class-ideal for Keramas' mechanical, hollow sections.
Weather and winds are classic northwest monsoon. The distribution is weighted heavily toward W and WSW breezes, but speeds are mostly light, and the offshore NW/WNW component is well represented, leaving the bay clean for a majority of the month. The wet season peaks with 9.86mm/day of rain, air temps around 26.9°C (24.5-31.4°C) and a balmy 29.1°C water temp. Tropical showers are part of the deal, but they often pass quickly and leave behind light winds and groomed long-period swell.
