Conditions at G-Land in December
December: Monsoon Returns, Quality Suffers
December marks the full return of the northwest monsoon, and G-Land's wind quality takes the biggest hit of the year. Ideal wind falls to 20%, with W winds at 25.8%, WSW at 18.8%, WNW at 9.3%, and SW at 9.8%-a recipe for bumpy, onshore-affected conditions on the west-facing reef. The swell side is still reasonably healthy: average height 1.6m (5ft), period 12.6s, with SSW (59.5%) and SW (33.6%) combining for over 93% of the wave energy. Rain jumps to 7.12 mm/day, air temperatures are 27.0°C, and water temperature is 29.1°C. There are surfable days, especially if a temporary SE trade surge or storm swell pops up, but December is generally a grind compared to the April-October glory window.
