The Lowdown
Alright folks, it’s Rusty here. Let's have a straight-up look at what’s on the menu for the next couple of weeks.
Right off the bat, I gotta be honest with you – this is a tough one. We’ve got a solid 16-day window, but the first stretch is pretty grim. The wind is locked in from the east-northeast, blowing cross-on, and it’s just chopping everything up. We’re looking at a long, quiet run from now until the start of September with no real surf to get excited about.
Waiehu beach park is the only spot on the cards, a reef and point setup that’s generally consistent and works best on a NNE swell. But the wind’s just not playing ball. From Saturday the 22nd of August right through to Tuesday the 1st of September, the wave comment says it all: "poor surf conditions." Every single session is the same story – cross-onshore breeze, moderate energy in the water (combined swell energy mostly in the 200-400 range), and a messy surface. The swell sits around 4 ft to 6 ft, mostly from the east, but with a short, weak period of 6 to 9 seconds. It’s just not doing anything for this break. The water temp is sitting at 80°F with no real anomaly, so that’s about normal for the time of year.
Now, there is a tiny flicker of hope on Wednesday the 2nd of September. The morning shows a "marginal surf forecast" – the wind drops right back to almost nothing, just 3 mph from the NE, and the swell is 5 ft from the ENE. It’s still cross-on, but the light wind means it could clean up a bit. The energy is moderate (290). It’s not a standout by any stretch, but it’s the best looking window in a long, dry spell.
After that, the wind picks back up and we’re back into choppy, poor conditions through to the end of the period. The swell actually builds towards the end, hitting 6 ft on Saturday the 5th of September with a very long period of 13 seconds and strong energy (1042). That’s a proper groundswell, but the cross-onshore wind at 16 mph will ruin it. That setup would be more interesting for kite surfing than paddle surfing given the conditions.
So, the honest truth? There’s no true standout here. The only real sniff of a session is that Wednesday morning on the 2nd of September, and even then, it’s marginal. If you’re desperate, that’s your window. Otherwise, this is a blank run that’s pretty normal for this area when the trade winds lock in.
Rusty.

Further information to help with frequently asked questions about our surf forecast for Waiehu beach park may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
