Conditions at Manly in April
April: Longer Periods, Fading Offshore Flow
April sees the average period climb to 9.4s, giving the surf more push as autumn takes hold. Height remains at 5ft (1.7m), but quality becomes more selective because ideal wind drops to 36%. The swell rose shifts harder into the SSE/S/SE quadrant: SSE and S directions combined account for over 30% of the wave energy, and there is a growing SSW/SW component - closer to Manly's preferred window. The trade-off is wind. S/SW and WSW/W winds become more prominent, and those are onshore directions for a west-facing beach. A dawn session before the seabreeze kicks up will often reveal clean, longer-period 4-6ft (1.2-1.8m) surf with real power; wait too long and it turns lumpy. Air temps drop to 19-20°C and water remains warm at 22°C.
