Conditions at Adonis in December
December: Small but Clean, Northeast Monsoon Resets
December closes out the year in full northeast monsoon mode. Winds are dominated by NE/ENE trades, and while those are cross-shore rather than perfectly offshore, the light speeds and absence of strong onshore wind keep the surface reasonably clean. Ideal conditions hover around 46%. The swell returns to a smaller 1.1m (3.6ft) average with a shorter 8.9s period, spread broadly from E/ESE through SE and S. That broad spread is actually favorable for Adonis, with the ESE/SE/SSE/S quadrant representing roughly 44% of all wave directions. Rain is moderate at 5.81 mm/day, air temperature is 27.2°C, and the water temperature is 28.6°C. Expect small, rippable, fun waves with occasional punchy sets when the period bumps above 10s.
