Conditions at Injidup Carpark in December
December: Early Summer, Smaller but Clean
December settles into the early summer pattern at Injidup Carpark. The average swell holds around 1.9m, the period eases to 11.9s, and the swell window is dominated by SSW and SW directions - together about 69% of the total. The true west/northwest swells are almost absent, which makes this a less consistent month for the reef's preferred wave shape.
The wind regime is strongly offshore in direction, with SSE (20%), S (20%) and SSW (14%) leading the rose, but ideal surfing wind only 15% of the time due to variable speeds and the daily sea breeze. Air temperatures reach 19.2°C, water temperature is 19.9°C and rainfall is minimal at 0.42 mm/day. It is a perfect month for dawn patrol: smaller, cleaner, warm water and fun waves, but without the heavy winter power that makes this spot truly light up.
