Waipio Valley Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s cooking for Waipio Valley over the next couple of weeks.

Right off the bat, I gotta be honest with you – this stretch is looking pretty grim for a solid week and a half. The surf is there, but the wind is a total pest. We’ve got a persistent cross-onshore breeze from the ENE and E, blowing 15 to 19 mph, just tearing the place up. The combined wave energy is moderate at best, hanging around the 400s to 600s, and the swell is a short-period 8 seconds from the ENE. That’s a recipe for choppy, blown-out junk. The water temp is sitting at 81°, which is about average for this time of year, so at least you won’t be cold while you’re getting frustrated.

This nasty run of poor conditions stretches all the way from the 31st of August through to the 7th of September. The swell actually builds into a moderate 7 ft to 7 ft, but with that wind, it’s just a mess. Even on the 4th and 5th, when the period jumps to 13 seconds and the energy spikes into the strong range (1600 to 1799), the cross-onshore wind holds it back from being any good. The swell is too big for beginners at over 5 ft, and the wind is punishing.

Now, the one true standout. On Monday the 7th of September, the forecast finally gives us a break. The wind drops to practically nothing from the W, turning glassy. The swell drops to 7 ft from the NE with a 10-second period, which is a nice groundswell. The combined energy is still a moderate 998, but with glassy conditions, that’s the key. This is a river break, so a longer period swell like this can set up some nice lines. Keep in mind, the crowds are listed as "sometimes," so you might have company, but for this spot, it’s probably the best session in the whole window. This is for intermediate surfers, as the size is right at the edge for beginners.

After that little window of hope, it’s back to the grind. From the 8th of September onwards, the wind swings back cross-onshore, the swell drops back to a short, weak period, and the energy fades to weak levels – down in the 100s by the 15th. The last few days are just tiny, weak, and blown out. It’s a flat, frustrating end to the outlook.

So, if you’re keen, keep your eyes on that Monday the 7th. The rest of it? Honestly, this setup looks more interesting for a kite surfer than a paddle surfer for most of the period.

Rusty.
