January: The Summer Slump with Southern Ocean Muscle
January is peak summer in the southern hemisphere, and the swell machine throttles back to an average of 1.9m (6.2ft) with a period of 11.8s. The dominant swell directions are SSW and SW, making up 33.5% and 38.6% of the total respectively, with the bulk of energy sitting in the 1.5-2.5m (5-8ft) range. That is a solid, rippable southwest groundswell for the exposed west-south-west facing beaches. The catch is the wind. The subtropical ridge sets up a strong SSE/S flow 46.9% of the time, with a classic afternoon sea breeze blowing straight into the coast and chopping up the surface. Ideal offshore E/ESE winds only arrive around 14% of the time, mostly in the morning before the seabreeze kicks in. With water temp at 20.4°C and air averaging 20.2°C, a board-shorts-and-summer-rashie setup is all you need when you pick off the dawn patrol windows.
