April: Clean Winds, Wrong Direction
April delivers the best wind statistics so far - ideal wind for surfing is present 30 percent of the time, with offshore flow from SW (9.1 percent), WSW (7.0 percent), and W (7.6 percent) combining nicely. Yet the swell direction flips toward the south: SE (29.9 percent), SSE (18.6 percent), and S (16.0 percent) dominate, while the favourable ESE drops to 18.8 percent and NE/ENE/E almost vanish. The average swell height is 3ft (0.9m), but the period drops to 8.2s, indicating less organised, more locally wind-driven waves. For Ikumi, this is a frustrating month - the water may be glassy, but the wave quality is poor, with soft, sectiony lines that rarely hold up. Rain becomes more frequent (5.03 mm/day), air warms to 15.9°C, and sea temperature climbs to 16.8°C. It's a month for longboarding in clean but weak conditions.
