The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s on the cards for this stretch.
Right off the bat, it’s a slow start. We’ve got a whole lot of nothing for the first several days, with no real surf to speak of. The wind is all over the shop, mostly cross or cross-onshore, and the swell is tiny and weak. It’s a bit of a flat spell, so don’t even bother paddling out until we get to the weekend.
The first real glimmer of hope shows up on the morning of Sunday, the 9th of August. James Kealoha Beach Park is the only spot in the mix, and while it’s a reef break that’s fairly consistent, it’s also a beginner-friendly spot. That morning, we’ve got a 6ft swell from the east, with a period of 8 seconds. The wind turns cross-offshore, which is a big deal – it’ll clean things up nicely. The combined energy hits 403 (moderate), so there’s some push behind it. The water temp is sitting at 80°, which is pretty much normal for this time of year. This is the standout of the whole outlook, but don’t get too excited – it’s a one-off window. The afternoon goes a bit messy with cross-shore wind, and then we’re back into marginal or poor conditions for days after.
The second week is a bit of a write-off. The swell tries to pick up around the 16th of August, with a 7ft east-northeast swell on Sunday morning, but the wind is cross-onshore at 15 km/h, making it choppy. The energy is strong (512), but the quality just isn’t there for a good paddle session. That kind of size with onshore wind is more of a kite-surfing setup than a clean surf day. After that, it’s more of the same – small, weak, and messy right through to the 20th.
If you’re a beginner, that Sunday morning window on the 9th is your best shot. Just keep an eye on the wind and be ready to go early. For everyone else, it’s a waiting game.
Rusty.
