December: Powerful Westerlies and Unreliable Angles
December closes the year with the most reliable offshore winds but the least favorable swell direction at First Point. The average swell height is 0.8m (2.5ft) and the period is a solid 12.4s, yet the energy is dominated by W (53.6%) and WSW (29.5%) swells, with true S/SSW directions making up only about 3% of the total. This means the point rarely sees its ideal swell angle. Instead, you get longer-period westerly groundswell that is powerful but often shadowed or poorly aligned for the break. The wind forecast is the silver lining: ideal wind peaks at 60% for the year, with NNE (20.1%) and NNW (12.8%) leading the offshore flow. When a low-pressure system sends a more southerly component into the region, First Point can suddenly fire with clean, hollow rights under glassy conditions. Air temps sit at 13.3°C, water temps cool to 14.4°C, and precipitation returns to 2.30 mm/day. December is a month for checking the angles daily - when it all lines up, it is worth it.
