Conditions at Abrolhos Islands in April
April: The Door to Winter Opens
April is the first true shoulder month at Abrolhos. The average swell height holds at 2.2m (7ft), but the average period jumps to 13.2s - a serious step up in power. The swell direction becomes more mixed: SSW still leads at 35.1%, but SW now contributes 22.2%, giving the surf a more west in the mix. This helps the southeast-facing reefs line up better than the pure southerly pulses of summer.
Wind is still problematic, with SSE at 26.8% and S at 17.0%, but ideal offshore wind increases to 8% of the time. That means a few more clean sessions, generally around dawn before the onshore flow strengthens. When the offshore W-NW breeze does align, the 13s-plus swell produces powerful, rippable reef waves. Water temperature holds at 23.8°C, air temperature averages 22.5°C, and rainfall is modest at 0.64 mm/day.
