April: Real Groundswell Arrives
April is where Leblon starts to shine. The average swell height jumps to 1.4m (4.5ft) with a 10.6s period, and the wave direction is now strongly in the south quadrant: SSE 31.3%, S 30.5%, SE 22.7%, SSW 4.9%. Nearly half of all swells are in the 1-1.5m (3.5-5ft) range, and a solid 27% are 1.5m (5ft) or bigger, including the season's first meaningful 2-2.5m pulses. Offshore wind reliability sits at 48%, while ENE (14.0%) and E (14.1%) winds remain the most frequent directions. The increased S/SSW swell easily overcomes the ordinary afternoon texture. Air temps cool to 24.1°C, water holds at 23.8°C, and rainfall drops to 3.31 mm/day. This is the true start of the best surf season.
