December: Short-Period Easterly Windswell Returns
December is the beginning of the low season for Coke's. The northeast monsoon locks in, and the swell rose becomes dominated by ENE at 41.4% and E at 23%. That is a compass quadrant well away from Coke's preferred SSE/S/SSW window. Average wave period drops to 6.9s, placing the swell squarely in the short-period windswell category, and average height is 1.0m but with less organization.
Winds are mostly NE at 20% and ENE at 27%, which are cross-offshore at this reef and do keep surfaces fairly clean. The ideal wind percentage is 43%, but the waves themselves lack the direction and period to generate proper barrel shape. Water temperature is 28.6°C, air is 27.3°C, and rain is moderate at 5.37mm per day. For the Coke's devotee, December is a month for banked swell maps and low expectations - unless a rare southern hemisphere pulse lines up with a N/NW wind window.
