Conditions at Coffee Bay in March
March: Autumn Shoulder Begins to Clean Up
March is the first month where the surf quality equation starts to improve. Average period jumps to 10.3s, putting more Southern Ocean groundswell into the mix, while the average height holds at a solid 2.0m (6.5ft). Directionally, the spread is still broad, but E (12.2%), ESE (12.6%), SE (14.0%) and SSE (16.1%) are well represented, and S (17.4%) continues to feed the bay with wraparound energy. The 1.5-2.5m (5-8ft) range accounts for nearly three quarters of all waves, so when you catch it right the bay is far from tiny. Wind conditions improve: the ideal offshore wind window stretches to 18%, and while NE (24%) still dominates, there are more clean days sprinkled in as frontal systems pass to the south. Water temps are still warm at 24.2°C, and overall conditions are more comfortable than the peak summer humidity. This is a genuine transition month - good days become more frequent, but patience is still needed.
