Conditions at Snapper Rocks in October
October: Northerly Winds Dominate
October is dominated by the onshore northerly regime. NNW is the single most common wind direction at 21.9%, and N/NNE/NE add another 20.2%, leaving ideal wind at just 35%. Average wave height is 3-4ft (0.9-1.2m), but the period is only 7.4s - short-period, textured, wind-affected waves.
The swell distribution includes E (22.7%), ENE (16.5%), ESE (19.2%) and NNE (12.8%), so there is plenty of energy in the water. The problem is the surface: NNW winds create bumpy, unruly conditions that reduce the Superbank to close-outs. Only when a front swings the wind to the S/SW does the same swell turn into clean, ridable waves. Water temp rises to 21.5°C, air is 14.4-28.3°C, and rainfall is 2.50mm/day.
