Conditions at Winkipop in December
December: Summer Arrives, Seabreeze Rules
December delivers the first true taste of summer. The average swell height is back to 1.2m, the period drops to 11.1s, and ideal wind falls to 29%. The good news is that SSW/SW groundswell remains the dominant source, combining for 76% of wave energy, so there is still plenty of push at the reef. Air temperatures warm to 16.2°C and water temperatures rise to 16.8°C. Rainfall is lower at 1.76mm/day, but the synoptic pattern is all about the sub-tropical ridge.
The daily ESE/SE/SSE seabreeze becomes the main character, chopping up the surface by midday. Early morning, however, can be clean and fun, with playful 3-5ft waves from the southwest quadrant. Summer at Winkipop is not the main event, but the points still offer plenty of rippable waves if you work the clock.
