December: Big Swell, Rough Conditions
December brings the Northeast Monsoon to full strength, and Pilar sees some of its fattest swell statistics of the year. Average height is 5ft (1.6m) at a solid 10.0s period, with 60 percent from the NE and 25 percent from the ENE. But the monsoon wind is onshore and relentless - ENE (21 percent), E (21 percent), ESE (14 percent) and NE (13 percent) - while ideal offshore wind sits at just 5 percent. The result is big, powerful, but often stormy surf that is hard to surf unless you find a rare wind shift. Air temps are around 28°C (82°F), water temperature is 28°C (83°F), and rain is heavy at 15mm/day.
