April: More Power, Shrinking Wind Windows
As the Southern Ocean gears up, April sees the average swell climb to 6.9ft (2.1m) and the average period to 11.7s. The wave distribution is now heavily concentrated in the 5-8ft (1.5-2.5m) range, with SSW at 27.8 per cent, S at 16.2 per cent and SW at 11.6 per cent. This is proper winter-swell precursor energy - solid, powerful and capable of lighting up the outer reefs. However, the ideal offshore wind frequency drops to 25 per cent. The wind rose shows a strong WSW/W component (30.5 per cent combined), which can be cross-offshore, while the E/ENE flow remains at 24.2 per cent. The N/NNE/NE/NNW onshore quadrant is still a minor player at around 13 per cent. Air temperatures average 19.8°C, water is 18.8°C and rain is 1.28 mm/day. April rewards the surfer who waits for a post-frontal SSE or SW wind shift.
