Waimanalo Surf Forecast and Surf Report

Alright, Rusty here. Let’s have a look at what’s on the table for this stretch.

Right off the bat, I gotta be straight with you – this 16-day run is a tough one. For Waimanalo, we’re looking at a pretty bleak stretch of surf. The first proper recommendation doesn’t even appear until July 10th, and even then, it’s a struggle. The whole period is dominated by onshore winds, mostly from the ENE, blowing straight into the beach and making a mess of things. The swell is not cooperating either, coming from the ENE and NE with short periods of 6 to 8 seconds, which means weak, choppy, and lumpy waves.

Starting Friday afternoon, July 10th, we’ve got poor surf conditions with a 6 ft swell from the ENE and a period of just 7 seconds. The combined energy is 348 (moderate), but that ENE wind is blowing at 22 mph right onshore, so it’s going to be a bumpy, blown-out mess. This vibe continues straight through Saturday and Sunday the 11th and 12th, with similar sized swell but winds cranking up to 25 mph on Sunday morning. The wave energy jumps up a bit (531) but with that wind, it’s all junk.

By Monday the 13th and Tuesday the 14th, the swell drops a touch to around 5 to 6 ft, but the onshore wind just won’t quit. It’s still poor quality. Mid-week, Wednesday the 15th, the swell dips to 4 ft, and we even get some rain showers. It’s just not worth paddling out.

Now, into the second week – from July 16th onward – the wind swings a bit more cross-onshore, but it’s still fresh and messy. The wave comment mentions “fresh cross-onshore and lumpy” or “strong cross-onshore and messy.” The swell stays between 5 ft and 7 ft, with periods still short (6 to 7 seconds), and combined energy hits 477 on July 18th. That’s moderate wave energy, but with the wind and short period, it’s a chop-fest. Just not good for a clean ride.

Later on, around July 22nd, we see a weird little spike in period – 14 seconds – but the swell drops to 2 ft to 2 ft. That long period is interesting for a reef or point break, but at this size and with stiff onshore wind, it’s barely a ripple. Combined energy is 357 (moderate), but it’s too small to do anything with.

Honestly, there’s no standout in this whole 16-day window. The best I could say is maybe early on July 11th, but with 22 mph onshore winds, you’d be fighting a losing battle. For a break that’s fairly consistent and exposed to the NE, this is a real bummer. It’s the kind of pattern where the wind just ruins what could be a fun summer swell. If you’re a kite surfer, the strong cross-onshore conditions and moderate swell energy (477 to 531) might look interesting, but for a paddle surfer, you’re better off waiting for the next change.

Water temp is sitting at 79°F on July 10th, with a zero anomaly – so it’s about average for the time of year. No surprises there.

Rusty.
