Conditions at Snapper Rocks in March
March: Autumn's Golden Window
March is where reliability starts to trump raw power. Average swell height remains at 4ft (1.2m), period is 8.5s, and E/ESE swells still dominate at 44.5% and 30.0%. The wind pattern shifts toward the offshore quadrant: S (12.2%), SSW (4.5%) and SW (1.5%) become more common, while NNW (8.7%) and NNE (4.4%) onshore flow shrinks. Ideal wind reaches 56%.
The result is a cleaner, more organized surf day after day. Most waves are in the 3-5ft (0.9-1.5m) range with occasional 5-6ft (1.5-1.8m) sets, and the trade-wind lines hold their shape under offshore breezes. Water is still warm at 25.6°C, air temps average 20.1-29.7°C, and rainfall is moderate at 4.83mm/day.
