Conditions at Sao Conrado in April
April: Winter Groundswell Starts Filling
April marks the true onset of surf season at Sao Conrado. Average wave heights build to 4-5ft (1.4m) with periods averaging 10.6s, and the swell is now strongly focused in the optimal SE/SSE/S window: SSE 31%, S 30%, SE 23%, with SSW beginning to contribute around 5%. The height distribution shows a healthy slice of 5-8ft (1.5-2.5m) energy, especially from S and SSE swells, so the beach break starts to show hollow, more critical sections. The catch is wind: ideal offshore flow drops to 47%, and ENE/E winds still feature heavily; SW/WSW tendencies also grow as cold fronts pass. Air temps cool to 24.1°C, water temp is at its warmest around 23.8°C, and precipitation falls to 3.31mm/day. April is a sweet spot for bigger, cleaner surf if you pick the post-frontal offshore windows.
