April: The Wind Turns, The Pass Comes Alive
April is the proverbial switch-over. Cold fronts tracking from the Southern Ocean start pushing through the Tasman Sea, and the S/SSW/SW offshore flow jumps to 39.8% of the wind record - versus just 19.6% for the onshore north quadrant. The ideal wind percentage jumps by seven points from March to 25%, making this the first month of the true surf season.
Swell energy remains substantial: 5.5ft (1.7m) average height and 9.2s period, with the dominant ESE (26.4%) and SE (21.9%) directions producing long grinding right-handers down the point. The 6.5-8ft (2-2.5m) bracket now accounts for more than a tenth of the wave measurements. Air cools to 22.6°C (73°F), water to 24.4°C (76°F). If you're planning a Byron trip, April is the choke point where quality becomes reliable.
