Waimanalo Surf Forecast and Surf Report

Alright, let’s get straight into it. The outlook here is a long stretch of pretty ordinary conditions. From Sunday the 2nd of August right through to Monday the 17th, every single session is labelled as poor surf. There’s simply no standout, no hidden gem, no window where it all comes together. The wind is relentless from the ENE, mostly fresh breezes, keeping the surface messy. The swell is coming from the same ENE direction, which is exactly the opposite of what Waimanalo prefers – it likes a NE swell for best shape. So we’re dealing with onshore winds and onshore swell, which is a tough combo.

Water temperature is sitting at 80°F with a tiny anomaly of 0.9°F, so pretty much bang on average for the time of year, no surprises there.

Let’s talk about the waves. On Sunday morning the 2nd, we’ve got 7ft of swell, but it’s short period at 8 seconds and all onshore, so it’s going to be a bumpy, wind-affected mess with moderate energy (856). That’s the biggest size we see, but it’s not surfable quality. By Monday the 3rd, the swell drops to 6ft, still ENE, still onshore. The period stays short, mostly 7 to 8 seconds through the whole forecast, which means weak, disorganised waves. The energy levels bounce around between 88 and 515, so mostly weak to moderate, but it’s all wasted by the wind.

There’s a brief moment on Tuesday the 4th where the period lifts to 11 seconds, with swell around 5ft to 5ft, and the wind eases to a gentle breeze. That’s the closest we get to a clean-ish window. But the swell direction is still ENE, and the break is exposed to that direction, so it’s not offering the ideal shape. The energy is moderate (515 on Tuesday morning). For a beginner-friendly spot like Waimanalo, the size is okay, but the wind locks it out.

From the 7th onward, the swell drops under 5ft and the period gets short again, with winds building back to fresh breeze territory. The 8th and 9th see some cross-onshore wind and lumpy conditions, with swell around 6ft to 6ft, but the period is a whimpy 7 seconds. That’s just not going to produce any decent shape.

The whole second week, from the 10th to the 17th, is more of the same: ENE wind, ENE swell, short period, onshore conditions. The energy is weak to moderate (167 to 364), and the wave comment is always “poor surf conditions.” There’s no point picking a day – it’s a flat, frustrating run.

If you’re a kiter, the consistent wind and moderate swell might make this interesting, but for a surfer, it’s a write-off. The crowds are sometimes an issue at Waimanalo, but honestly, with this forecast, you won’t have to worry about that.
