January: The Trade Wind Grovel
January is the heart of the summer trade-wind season on the NSW coast. Swell height averages 1.6m (5.2ft) with a short-period 8.5s average, so most surf falls into the punchy but rideable category. The wave rose shows a strong east-northeast through southeast bias: ENE accounts for 18.2%, E 16.3%, ESE 13.1%, SE 14.4% and NE 11.2%, meaning the optimal NE-ENE-E-ESE-SE swell window is well fed. However, the wind rose is the weak link. Ideal offshore winds from SW/WSW/W/WNW/NW only blow 20% of the time, while NE (13.5%), NNE (12.2%), SSE (12.5%) and S (12.6%) dominate. These onshore and cross-shore winds chop up the incoming swell, leaving mostly lumpy, wind-affected conditions. Head to early mornings when a land breeze or westerly edge may clean it up; air temps average 21.4°C, water is a warm 22.0°C and precipitation runs at 2.75mm/day.
