Conditions at Contreiras in April
April: Shoulder Season Gold
April is a sweet spot between winter power and spring manageability. The average swell height settles at 2.1m (6.9ft), with a period of 11.2s, so you still get solid power but the extreme XL events become less frequent. The directional distribution remains ideal: NNW leads at 32.1 percent, NW adds 19.0 percent, and WNW contributes 7.5 percent. The 1-2m (3.3-6.6ft) band dominates, with a good amount of 2-2.5m (6.6-8.2ft) waves filtering in from the NNW/NW window. Wind quality improves slightly, with NNE and NE still the most common directions but lighter speeds overall. The SSW-SW-WSW-W offshore flow registers around 17 percent ideal conditions, and when the sea breeze cycle is delayed by a weak pressure gradient, the mornings can be clean and lined up. Air temperatures are milder at 14.1-20.2°C, water temperature has come back up to 18.3°C, and rainfall drops to 0.76mm/day. This is one of the best months for semi-clean, fun-to-slightly-overhead surf at Contreiras without the winter crowd intensity.
