Conditions at Alvor in April
April: Downshifting Swell with Clean Morning Windows
April marks a clear transition toward smaller surf. The average wave height drops to 1.1m (3.5ft) and the period eases to 10.8s, signalling a less energetic North Atlantic. The wave rose is still dominated by WNW 32.6 percent and NW 25.5 percent, with W at 17.0 percent and WSW at 6.2 percent; direct S/SSW/SW energy is a small share, so Alvor increasingly relies on wrapped west-northwest groundswell. Ideal wind falls to 32 percent, with NNW 21.8 percent and NW 15.8 percent creating clean morning surfaces before the sea breeze builds. Water temperature rises to 16.4°C, air averages 15.8°C, and rain remains active at 2.03mm/day. The best April sessions come from leftover winter swells that still carry enough period to wrap around Ponta de Piedade and break with shape on Alvor's sandbars. It is rippable, fun, and often less crowded than winter - just not as consistent.
