December: Summer Swell, Polished Performance
December closes the year at the same place summer began - with a 2.0m average swell and a short, punchy 10.7s period. SSW is back to a commanding 29.1%, with SW at 18.1% and S at 14.6%. The south/south-west sources are rich, and the wave height bins show a healthy cluster of 1.5-2.5m (5-8ft) waves, with only a modest amount of XL energy. This is a user-friendly swell regime that perfects the pier's wedges and re-forms.
Ideal wind returns to 28%, tied for the best of the year. WSW (15.6%) and SW (12.6%) are strong offshore vectors, but the ever-present E at 16.6% and ENE at 9.2% still mark the afternoons as the enemy. Morning sessions during the outgoing tide are where it's at. Water temperature is back up to a balmy 19.6°C and air temp to 20.8°C, making December a true celebration: clean, warm, and firing enough to end the year with a smile.
