Conditions at Matadouro in April
April: The Shoulder Season Shifts
April marks the first real step down from winter. Average swell height drops to around 6.5ft (2.0m) and the average period shortens to 11.1s. The wave direction data is dominated by NW (28.0%) and WNW (21.3%), with a major NNW component (20.0%) as the Atlantic starts to disorganize. Matadouro still gets its fair share of groundswell, but it is less heavy and more rounded than the winter months.
The limiting factor is wind. Only 14% of April hours show ideal offshore flow. NNW winds blow at 28.6% - the highest share so far - and the N/NW quadrant is common, especially in the afternoons. This makes for a lot of lumpy, cross-offshore surf. Early mornings can be glassy and fun, but the window is small. If an easterly wind event lines up with a solid NW swell, the waves at Matadouro will still be very, very good.
Water temperature is 15.7°C, air temperature averages 14.7°C and daily precipitation is 1.88mm. A 3/2mm wetsuit will start to work for most surfers.
