April: Bigger South Swell, Mixed Winds
April marks the transition into the green season. The South Pacific storm track is now fully active, sending long-period SSW swell across the equator. The average period peaks at 14.1s, while average height jumps to 1.2m (4ft). SSW dominates massively at 85.6%, and 68.5% of all swell sits in the 1-1.5m (3-5ft) range, with 9.1% reaching 1.5-2m (5-6ft). The trade-off is wind: ideal offshore flow drops to 47%, and rain increases to 1.06mm/day as the ITCZ edges north. Water temp warms to 29.7°C. Dawn patrol will be key, with cleaner conditions before the southerly sea breeze builds.
