Conditions at Mada's in December
December: Northeast Monsoon Mode and Small, Clean Lines
December marks the full arrival of the northeast monsoon. The swell rose rotates back to the east: E 23.1%, ENE 15.2%, ESE 17.4%, SE 9.4%, with SSE 4.8% and S 3.6%. The optimal ESE/SE/SSE/S window supplies 35.2% of the total energy, but the typical day sees smaller east/ENE trade swell pulsing past the point rather than true SSE/S groundswell. Average height is 3.3ft (1.0m), and period averages 6.4s, so everything sits in the small-to-fun, average/punchy category.
Wind quality remains decent. NE 14.6%, NNE 10.0% and ENE 11.7% are the most common directions, but NNW 10.3%, WNW 10.3% and NW 9.1% keep the offshore quadrant at 33.3%. Ideal wind reaches 49%, the highest of the year, giving plenty of clean, glassy sessions despite the modest swell. Rain ticks up to 5.81mm/day, air temp is 27.2°C, and water temp is 28.7°C. December is a consistent, user-friendly month: waist-to-chest-high walls, offshore mornings, and more longboard-friendly conditions than firing barrels.
