Conditions at Broadway Beach in December
December: Cold, Consistent and Fickle
December closes the year with the same midwinter recipe: average height around 2.3ft (0.7m), short period of 6.3s, and ideal wind of only 6%. The dominant swell directions are WNW, NW, and NNW, which are not ideal for this south-facing beach. Yet there is still a southern window, with S 9.0%, SSW 7.8%, SSE 7.6%, and SE 7.5% combining for about 32% of observations, and those pulses are more valuable than their magnitude suggests. The wind regime is dominated by strong WNW, NW, and NNW flow, especially when high pressure builds over the interior, so clean, cold, and hollow-looking conditions can line up even if the waves are small. Air temps average 5.5°C (42°F), water drops to 7.5°C (45°F), and winter gear is non-negotiable. It is a picky, low-percentage month, but the few clean windows are worth the hunt.
