Conditions at Nahoon Reef in April
April: Power Ramps Up, Winds Turn Friendly
April is where the season really starts to hit its stride. Average swell height reaches 2.0m and the period stretches to 11.2s, which is the first real taste of long-period winter groundswell. The E/ESE/SE/SSE direction still supplies 43.0 per cent of the energy, but S at 20.3 per cent and SSW at 20.0 per cent begin to shoulder the load. Plenty of swell arrives in the 1.5-2m and 2-2.5m classes - SSW alone puts 10.2 per cent in the 1.5-2m bin and 7.5 per cent in the 2-2.5m bin. The big news is wind: ideal surfing wind rises to 30 per cent, the best since summer, with W, WNW, NW and NNW all becoming noticeably more common. That means more clean, lined-up mornings on this SE-facing reef as the ocean transitions into winter mode.
Air temperatures cool to 21.4°C, water temperature drops to 20.8°C, and rainfall retreats to 2.84mm/day. The drier, cooler air mass stabilises the wind and tends to favour more consistent offshore morning sessions, making April one of the more dependable months for quality at Nahoon.
