Conditions at Jailbreaks in December
December: NE Monsoon Gears Up
December marks the arrival of the northeast monsoon, and the winds swing back to the NE/ENE quadrant (NE 18.7%, ENE 27.5%). Ideal offshore wind percentages drop to 30 percent, and the average period falls to 6.9s. The swell still has a strong ENE (41.4%) and E (23.0%) component, with E and ESE/SE directions contributing about 38 percent optimal. Wave heights are around 1.0m (3.3ft), with a notable block of 1-1.5m (3-5ft) ENE groundswell. The trade wind surface is rougher, and the shorter period makes the waves more average and punchy rather than powerful. Yet the E component can still wrap into Jailbreaks, especially when the NW-NNW flow shows up. Air sits at 27.3°C, water at 28.6°C, and rainfall at 5.37 mm/day. It's a fair, workable month with occasional windows.
