Conditions at Praia Grande in April
April: Shoulder-Season Groundswell
April sits on the spring side of the divide. The average wave height has slipped to 6.5ft (2.0m) and the period to 11.1 seconds - still solid and punchy, but with fewer oversized days. Swell direction remains excellent for exposure: NW 28.0 percent, WNW 21.3 percent, NNW 20.0 percent, and W 6.4 percent. The ocean is still producing rideable groundswell; it is the wind that becomes the bigger issue. NNW wind now accounts for 31.4 percent of observations, with NW at 10.9 percent and N at 7.9 percent. Ideal offshore flow falls to 11 percent. The pattern is increasingly driven by a strong thermal gradient, so the morning hours are often the only time the sea breeze is calm enough for the east/southeast land breeze to work. Air temperatures are warmer at 14.7°C (min 7.1°C, max 28.4°C), precipitation is 1.88 mm/day, and water temperature climbs to 15.6°C. Expect decent waves with a side of challenging wind.
