Waimanalo Surf Forecast and Surf Report

Yo, it’s Rusty.

Alright, let’s be straight up: the next 16 days at Waimanalo are a tough watch. The forecast is pretty much a long stretch of poor surf conditions, with only one real window that looks worth paddling out for. You’ll have to wait through a lot of choppy, wind-affected days to get to it.

The swell hangs around in the 5ft to 8ft range for most of the period, but the problem is the wind. From the get-go on Monday 27 July, it’s a strong onshore NE breeze at 19 mph, and that sets the tone for the whole run. The combined swell energy is moderate to strong (967 to 983), but with that wind, it’s just messy.

The standout is Wednesday morning, 29 July. That’s your window. The wind goes glassy, swinging to a light southerly at 3 mph, and the swell is a solid 7ft from the ENE with a 10-second period. The combined energy is moderate (821), and the water temp is a comfortable 80°F, which is about average for late July. The waves should be clean and well-shaped, with that long period pushing in some proper groundswell. It’s a fairly consistent spot, but crowds are possible here, so get there early. This is your best session in the whole outlook.

After that, it’s back to the grind. From Wednesday afternoon through to the end of the first week, the wind picks up again, cross-onshore and onshore, with gusts up to 28 mph by Saturday 1 August. The swell gets bigger, hitting 8ft, but with the wind howling and the period dropping to 7-8 seconds, it’s just a lumpy, choppy mess. The combined energy stays in the moderate range, but it’s not surfable.

The second week, from 3 August onward, is more of the same. The wind stays strong from the ENE, mostly cross-onshore, and the swell fluctuates between 3ft and 8ft. The periods are short, mostly 7-9 seconds, so the waves are weak and wobbly. The combined energy drops to 280-463, which is weak to moderate. There’s nothing to get excited about there.

On Tuesday 11 August, the wind finally eases to a light ESE breeze at 6 mph, and the swell drops to 5ft from the NE with a 9-second period. The combined energy is weak (294), and the conditions are only marginal. It’s a small, cleanish day, but nothing special.

So, to sum it up: Wednesday morning, 29 July, is your one and only standout. Glassy, clean, and a solid 7ft. Everything else is a long, frustrating gap of onshore wind and poor surf. Hang tight, check the charts, and hope something changes.

Rusty.
