Conditions at The Bluff in January

January: Summer Heat, Shorter-Period Southern Swell

January at The Bluff averages 4.6ft (1.4m) of swell with a period of 11s, putting it in the powerful long-period class but on the weaker side of the annual spectrum. The swell rose is dominated by SSW and SW directions at 50.7% and 42.6% respectively, while the ideal W through NNW window accounts for only a few percent. Most waves fall between 3-5ft (1-1.5m) and 5-6ft (1.5-2m), with a scattering of bigger SSW pulses. The wind story is less encouraging: S and SSW flow combine for over 67%, often at 20-40kph, and true offshore E/ESE/SE/SSE wind occurs just 11% of the time. With air temps averaging 29.7°C and water temp at 25.1°C, the summer vibe is strong, but surf quality is a morning-only game.
