Conditions at Smiths Beach in December
December: Summer Kickoff with Surprise Potential
December marks the official start of summer, and the surf reflects it. Average swell height is 6ft (1.9m) with an 11.9-second period, and the dominant energy is SSW/SW once again. The quiet, long-range Indian Ocean groundswell remains just enough to keep the reef and beach breaks alive, but the overall energy level has dropped out of the winter window.
With high pressure firmly in control, the daily breeze is the main character. SSE/S winds dominate, strong afternoon sea breezes are common, and ideal offshore flow is at 18 percent. Water temperature climbs to 19.9°C and air to 19.2°C, with very little rain, so conditions are pleasant. On the odd occasion a tropical cyclone drifts across the Indian Ocean, Smiths can receive a rare NW/N groundswell - the direction this beach truly loves. It is not the most consistent month, but it is far from flat.
