Waikiki Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into what’s on the menu for the next stretch at Waikiki.

First off, the water temp is sitting around 81°, which is pretty much normal for this time of year, so no wetsuit worries—just your boardshorts. The overall pattern for the next 16 days is a lot of small, clean, but weak surf. The combined swell energy is mostly in the moderate range, with values between 200 and 700 (moderate wave energy), but it’s rarely pushing enough to make you run for your board. There’s a real gap in quality here: from now through the 24th and 25th, it’s poor. Monday the 24th and Tuesday the 25th are scrappy, with small messy swells and strong winds. Wednesday the 26th stays small, but we start to see a little more hope with offshore winds.

Now, the best we’ve got in this whole period is Thursday morning, the 27th of August. That’s your standout. Waikiki will see a S swell at 4 ft with a long 17-second period, and the combined energy hits 723 (moderate wave energy). That’s the most juice we get. The winds are offshore from the ENE at 19 mph, which means clean, lined-up waves. This is a solid call for beginners and intermediates—size is manageable, and the long period means the waves will have shape. But remember, with that long period, sets can be a bit fat at beach breaks, but Waikiki is a reef setup, so it should handle it well. Crowds are often here, so expect company.

After that, we slide back into small stuff. Friday the 28th and Saturday the 29th are mostly poor, with tiny swells under 3 ft and cross-off winds. Sunday the 30th is marginal, not enough to get excited about. Then Monday the 31st of August morning shows a glimmer: clean 2 ft SSW swell, offshore winds, and moderate energy (232)—still small, but the best of the rest.

The first week of September is a drag. From the 1st to the 5th, it’s all small, poor, or marginal, with fresh offshore winds keeping things clean but the swell never really delivering. The 5th of September (Saturday) does have a long-period SSW swell (20 seconds) and combined energy of 650, but the heights are only 2–3 ft, and the wind is cross-off, so it’s a tease. By the 6th and 7th, we’re back to weak, clean but tiny conditions. The 8th of September is the final day in the window, and it’s poor again.

Honestly, if you’re not a beginner or a longboarder cruising for a small wave, this 16-day run is pretty flat. The only real standout is Thursday morning the 27th—grab it if you can. Everything else is a waiting game. For kitesurfers, the strong, consistent trade winds might look more interesting than the tiny surf on offer.
