Conditions at Alibaba in April
April: The Transition Begins
April sees the winter machine start to switch off. Average swell height eases to 6.5ft (2.0m) and the period drops to 10.3s, still in the powerful long-period category but with noticeably less juice than March. The swell direction becomes even more NNE-dominated, with NNE (47.7%), N (20.4%) and NNW (20.0%) making up over 88% of the wave energy. The lack of SSW-SW/W swell is still the main limiting factor at Alibaba, and the increasing percentage of NNE swell means the waves arrive from a direction that requires maximum refraction to be surfable.
The wind pattern is still predominantly offshore from the NE, with NNE winds at 60.4% and NE winds at 29.5%, and the 20-40kph speeds remain common. Ideal wind percentages are low - just 8% - so despite the continued presence of swell, conditions are frequently textured by the trades. Air temperature warms slightly to 21.7°C, water holds at 22.5°C, and rainfall is very low at 0.26mm/day. Late April can still offer a final groundswell hit, but the window of opportunity is narrowing.
