Conditions at Playa Guiones in December
December: Back to Clean but Less Powerful
December brings the dry season into full swing and a return to the strong NE trade regime. NE winds account for 44.5% of all observations, with NNE at 12.1% and ENE at 11.5%, making it one of the most reliably offshore months of the year. Ideal wind is 60%. The trade-off is swell: the optimal SSW/SW/WSW/W quadrant drops to 61% and the average period falls to 11.7s, so the surf is more average-punchy than long-period powerful. Average heights sit at 4-5ft (1.2-1.5m) and 5-6ft (1.5-1.8m) pulses become much scarcer. Rain is minimal at 0.70mm/day, air is 27.1°C and water temp is 28.1°C. December is a clean, pleasant month for logging turns on the beachbreak, but the marquee SSW-swell days are a bonus rather than the norm.
