Conditions at Playa Malibu in December

December: Dry Season Cleanup

December is a full return to the dry season. Precipitation drops to 3.45 mm/day, air temperature is 25.8°C and water temp still sits warm at 28.3°C. The trade winds are firing; NNW wind accounts for 62.2% and N another 11.2%, giving a very high 72% ideal-wind reading. Offshore flow is abundant, which is why the surface is often glassy and inviting.

Swell, however, becomes more of a mix. SSW drops to 36.2% and SW to 16.6%, while N/NNW/NW directions combined make up a significant share of the low-period energy. Average height stays at 0.7m (2.3ft), but the average period falls to 9.0s, so a lot of that energy is shorter-period windswell. There are still clean 2-3ft (0.6-0.9m) S/SW groundswell pulses, but they are less consistent than the April-August window. For the traveling surfer, December offers the best chance of warm, glassy, small waves-just not much size.
