The Lowdown
Alright folks, Rusty here. Let’s look at what’s on the table for Waiehu beach park over the next couple of weeks.
Right now, the pattern is pretty grim. We’ve got a long stretch of poor to marginal conditions that starts now and runs all the way through the end of August. From Wednesday the 19th right through to Monday the 31st, the call is consistently poor surf – cross-onshore winds and choppy water. The swell is small to moderate, between 3 ft and 7 ft, but it’s mostly short-period windswell (6 to 8 seconds) and the wind just won’t let up. The combined energy is moderate at best, hitting three-digit numbers (183 to 688) until late in the month. It’s not a fun paddle out there.
Around the 31st of August, the swell starts to build. Monday morning sees 7 ft from the ENE, and by Monday afternoon it jumps to 8 ft with a very long 14-second period and a combined energy of 2257 – that’s a serious groundswell pushing in. But the wind is still cross-onshore, and the rating is only marginal. That big, long-period groundswell will be powerful, but at a beach-and-point setup like this, it might break a bit too straight and close out under that onshore breeze. Still, for experienced surfers who want some size, it’s a step in the right direction.
Then we hit the spot. Wednesday the 2nd of September is the standout. The morning brings 8 ft from the ENE, a solid 9-second period, and glassy conditions – that’s offshore from the WSW. The combined energy is 829, so moderate to strong. That’s clean, lined-up surf. The afternoon holds 7 ft from the ENE with a light cross-offshore breeze from the SE. On a reef and point break like Waiehu beach park, that’s prime. The water temp is a comfortable 80°F, which is bang on average for this time of year. Crowds are often an issue here, so expect company, but for quality waves, this is the day to clear your schedule.
Thursday the 3rd drops back off with risk of thunderstorms and onshore winds, so that Wednesday window is your best bet by far.
To be honest, the first week and a half is a washout – almost two weeks of nothing to write home about. But that one Wednesday in early September promises clean, punchy waves for the crew who can wait it out.
Rusty.
