April: The Transition Begins
April marks a real shift toward the green season and the best surf window of the year. The average wave period jumps to 13.1 seconds, signaling long-period groundswell, and the favorable SSW direction leaps to 26.5 percent, with SW adding another 9.1 percent. Swell heights concentrate in the fun-size 1-1.5m (3-5ft) range, and there are also decent pockets of 1.5-2m (5-7ft) from the ESE through SSE directions. The wind picture improves dramatically: ENE still blows 69.9 percent of the time, but more of it is moderate 20-30kph, and the ideal offshore wind percentage nearly doubles to 14 percent. This is the month when a morning glass-off can deliver clean, lined-up south groundswell before the trades pick up. Air temperatures reach 29.3°C, water temperature is 28.1°C, and the first real rainfall of the wet season, 0.58 mm/day, begins to settle the atmosphere.
