Conditions at Motunau Beach Island in April
April: Southern Ocean Swells Build
April sees Motunau truly waking up. The average period lengthens to 10.8s, while ideal wind frequency jumps to 48 percent - nearly half the days feature N/NW/NNW offshore flow. S swell is now a major player at 12.3 percent, supported by SSW at 2.5 percent, and the SSE direction adds another 16.3 percent. That combination boosts the likelihood of long-period, well-ordered groundswell wrapping into the southeast-facing bank. Average surf height holds around 4ft (1.2m), but the quality is noticeably better than summer. Water temperature falls to 14.6°C, so a 4/3 wetsuit becomes standard for the longer autumn sessions.
