Conditions at Puerto Madero in April

April: Proper Groundswell Arrives

April is when Puerto Madero starts showing real teeth. Average swell height climbs to 4.3ft (1.3m), the period stretches to 14.1s, and the SSW window erupts to 72.2% of the directional distribution; add in SW at 22% and the favorable S/SSW/SW/WSW window accounts for 98% of all incoming swell. The bread and butter is the rippable 3-5ft (1-1.5m) range, but there are now healthy pockets of 5-6.5ft (1.5-2m) SSW groundswell and occasional 6.5-8ft (2-2.5m) sets. Wind remains the main variable: ideal offshore conditions sit at 42%, with WSW and W flow still frequent; however, the long period means even a little chop won't kill the waves. Air temperatures average 28.7°C with a range of 24.6-32.5°C, water temperature heats up to 30.3°C, and rainfall increases to 2.56 mm/day as the wet season begins. This is the start of the serious Southern Hemisphere surf window.
