April: The Transition Fires Up
April is when Bells Beach genuinely comes alive. The average swell height remains steady at 1.3m (4ft), but the average period jumps to 12.5 seconds, giving the swell real power and consistency. SW swell leads the pack at 44.9%, with SSW close behind at 33.2% and WSW adding 4.2%. The height distribution is much healthier, with a large cluster in the 1-1.5m range and stronger percentages in the 1.5-2m and 2-2.5m brackets, particularly from SW.
Ideal offshore wind jumps to 43% of the time, and the wind rose becomes more balanced. The good NW-W-NNW quadrant has strong representation, with NW at 7.1%, NNW at 10.2%, WNW at 9.9% and W at 8.8%, allowing many more days of clean, groomed conditions. Water temperature cools to 17.4°C and average rain increases to 2.02 mm/day as weather systems become more active. This is a high-quality transition month: 3-6ft (0.9-1.8m) lines, longer intervals, and an increasing number of open, powerful Southern Ocean swells hitting the SE-facing bight.
