The Lowdown
Alright folks, Rusty here. Let's be straight with you – the next couple of weeks are looking pretty flat for the North Shore.
We're looking at a solid 16-day window, but the first few days are a write-off. From Saturday the 15th right through to the morning of Wednesday the 19th, it's all just tiny, weak junk with strong winds. Nothing to even bother paddling out for. The water temp is sitting right around 81°, which is pretty much bang on average for this time of year, so that's the only thing that's comfortable.
The first real glimmer of hope comes on Wednesday morning, the 19th of August. Laniakea Reef and Holtons might see a tiny 1 ft swell rolling in from the southwest. It's a long-period groundswell at 16 seconds, which is usually a sign of quality, but it's just so small. The combined energy is only 86 (weak). The wind will be a light cross-off, so it'll look clean, but you're battling "surfable waves but very ordinary conditions" at best. It's a beginner-friendly spot, but for most of us, it's not worth the effort.
Thursday the 20th and Friday the 21st offer a slight bump, with swell heights creeping up to 2 ft and 3 ft from the northeast and north-northeast. The periods are short though, around 6 to 7 seconds, so it's all windswell with no push. The combined energy barely cracks 50 (still weak). The wind stays light and cross-off, so it'll be clean, but again, it's super ordinary.
After that Friday afternoon, the surf just drops off a cliff. From the 21st afternoon all the way through to the end of the month, we're looking at near-flat conditions. Swell heights are mostly 0.7 ft to 1 ft, with barely any energy (combined energy values from 8 to 80, all weak). The wind is a constant moderate cross-off, so it'll be clean, but there's no wave to ride. It's a long, blank run.
If you're desperate, maybe the 30th of August (Sunday) shows a little pulse from the west-northwest at 1 ft with a 15-second period and combined energy of 80, but that's still a long way out and it's tiny. Honestly, for the next 16 days, the paddle surfing is a no-go. With these persistent trade winds and tiny swell, the setup looks more interesting for kite surfing than anything else.
