Conditions at Cloud 9 in April
April: Trade Winds Fading Into Fun Size
April marks the definitive shift toward cleaner but smaller surf. Average height drops to 3-4ft (1.1m) and the period remains a workable 9.4s. ENE is the dominant swell direction at 66%, with NE providing 27%; most of that energy sits in the 2-3ft (0.5-1m) and 3-5ft (1-1.5m) classes, so the reef is rippable and punchy rather than heavy. The wind story improves significantly: the onshore NE/ENE component falls to around 40%, E/ESE/SE winds become more common, and ideal offshore flow reaches 9%-nearly triple mid-winter levels. This is a good month for high-performance surfing without the constant battle against monsoon chop, though the biggest days still require a healthy swell event. Warm air at 27.8°C, water at 28.6°C, and mostly dry conditions with only 5.8mm/day of rain add to the appeal.
