Waimanalo Surf Forecast and Surf Report

Right, folks, Rusty here. I’ve had a look at what’s on offer for the next couple of weeks, and I gotta be straight with you – it’s a tough stretch. The whole 16-day window is looking pretty grim, with no real standouts to get excited about. The only spot with any solid data is Waimanalo, and even then, it’s a story of constant onshore winds, messy conditions, and poor surf quality. The pattern is pretty much set for the duration: persistent ENE winds, not letting up, keeping the ocean bumpy and uninviting.

The first real chance of anything surfable is from the very start, on Friday, July 31st. Waimanalo is showing a 7 ft swell from the east with a short period of 8 seconds, and combined wave energy is moderate at 747. But the wind is a strong onshore breeze from the ENE at 25 mph, which is just going to tear it up. The water temp is 80°, which is about normal for this time of year, so that’s one thing not to complain about. The conditions are just poor.

Moving into the weekend, Saturday the 1st and Sunday the 2nd of August, the swell bumps up a bit, hitting 8 ft on Saturday, but the energy climbs into the strong range (1107). That’s a lot of water moving, but with those same strong onshore winds, it’s going to be a messy, blown-out mess. This size is getting into the "experts only" territory, but honestly, with the wind, it’s not really surfable for anyone. The period stays short at 8 seconds, so no real shape to it.

The whole first week just repeats this pattern. The swell slowly drops from 8 ft down to 4 ft by the Wednesday the 5th, but the wind barely lets up. It shifts from a strong breeze to a moderate breeze, but it’s still onshore or cross-onshore the whole time. The energy drops from moderate to weak (213), but the commentary is consistently "poor surf conditions". There’s a moment on Tuesday the 4th where the period stretches to 11 seconds, which is a groundswell signal, but it’s still only 5 ft and with the wind on it, it’s just not going to be clean.

The second week, from the 7th of August onwards, is more of the same. The swell hovers around 4 ft to 6 ft, with short periods of 7 to 8 seconds, and the wind is a relentless fresh breeze from the ENE. The combined energy stays in the weak to low-moderate range (187 to 435). By the time we get to the 15th, the swell is down to 3 ft. There’s just no window of clean, light wind to make any of it worthwhile. The forecast is consistent, but it’s consistently bad for surf.

So, what’s the call? Honestly, there isn’t one. For the full 16 days, there are no good surf options. If you’re a paddle surfer, you’re better off finding something else to do. With that persistent onshore wind and the break being a beach setup, this whole stretch looks more interesting for kite surfing than catching a wave on a shortboard. The forecasts can always change, but as it stands, this is a blank run.

Rusty.
