Conditions at Isla Grande in April
April: Transition Begins, Window Emerges
April marks the beginning of the wind pattern transition. The average swell height is still a respectable 1.3m (4ft) with a period of 7.4s, and the NE swell contribution peaks at 92.8% - a beautiful directional setup. But the wind still blows from the onshore NE quadrant (NNE 35.8%, NE 40.7%) for the majority of the month. The good news: ideal offshore wind days climb to 5% as the first weak SW/W wind events of the spring push through. Rain increases to 3.25 mm/day and water temperature rises to 28.0°C, signaling the onset of the wet season. On the better days, especially during late-afternoon thermal westerlies, you can find clean 3-4ft (0.9-1.2m) waves. Still, April remains a fickle month for consistent quality.
