Conditions at Comporta in April
April: Consistency Fades, Fun Remains
April is a shoulder month where the ocean slowly lets go of winter. Average swell height drops to 5ft (1.5m) and the period eases to 11.1 seconds. WNW swell remains the primary source at 37 percent, with NW at 31 percent and W at 14 percent, but the share of smaller 3ft (0.9m) waves grows. The wind pattern becomes the main problem: ideal conditions fall to just 31 percent, and the prevailing NNW/NW/WNW flow is often onshore or cross-shore enough to put a bump on the face. Air temperatures warm to 15.3°C, rainfall stays moderate at 1.78 mm/day, and the water is 15.7°C. Surfing is still possible when an easterly offshore wind lines up with a long-period W/WNW pulse, but consistency is no longer guaranteed.
