Conditions at Costa Nova in April
April: Shoulder Season Swing
April is where winter power starts to fade into spring shoulder season. Average swell height drops to 2.0m (6-7ft) and period shortens to 11.0s, but the direction is still excellent, with NW (27.4 per cent) and WNW (23.2 per cent) combining for over half of all swell energy, and W adding another 8.7 per cent. The surf is generally solid, chest to overhead, and less intimidating than January, though still plenty capable of holding a good-size groundswell.
The wind is the bigger challenge. Ideal offshore conditions slip to just 30 per cent of the time as the NNW summer trade machine begins to spin up (24.6 per cent). However, light to moderate E/SE winds still appear regularly enough to groom the morning surf, especially before the seabreeze kicks in. With water temperature rising to 15.1°C and air averages around 13.9°C, a lighter winter suit becomes feasible, and the lower rain totals (2.91mm/day) make for more comfortable sessions.
