Riyue Bay (Riyuewan) Surf Forecast and Surf Report

Righto, Rusty here. Let's have a look at what the next couple of weeks are serving up for Riyue Bay.

The first few days of the outlook are a bit of a write-off, I’m not gonna lie. We’ve got some size on the charts from Thursday the 10th right through the weekend, but the wind is just all over the place and the surf quality is poor. That 3.3ft to 7.9ft swell from the ENE is there, but it's battling a Moderate to Fresh breeze, and the energy is weak to moderate (between 89 and 906). Honestly, it’s more of a frustrating wait than anything rideable.

Saturday the 12th and Sunday the 13th see the swell building up, with the combined energy hitting a solid 634 and 906, but again, that cross-off and cross wind, along with stormy conditions, are just trashing it. It’s a no-go.

Then we hit a bit of a lull from Monday the 14th. The swell drops off a cliff, and the wind turns onshore from the SE and S. Tuesday the 15th is a mess with a 9.8ft SSE swell (moderate energy of 1782), but it’s cross-onshore and chopped up. Nothing to get excited about.

Now, here’s where it gets interesting. Wednesday the 16th of September is the standout. Absolutely the best day of the whole run. We’re looking at a solid 14.8ft to 18.0ft swell from the S and SSW, and the energy is pumping hard at 3762 and 5118 – that’s proper juice. But the real magic is the morning: glassy conditions with that ESE breeze at just 5 km/h (3 mph). It’s going to be clean, but look, that’s some serious size. Anything over 8.2ft is strictly for the experienced crew. This is a big groundswell, and while it’s got a good period of 10 seconds, it’s going to be heavy. If you’re not a solid, confident surfer, sit this one out. The afternoon gets a bit of a cross-onshore bump, but the morning session is the one to chase. Expect a crowd, because the word will be out.

After that, the swell fades quick. Thursday the 17th still has some size (9.8-13.1ft) but the wind shifts, and the quality drops. By Friday the 18th, it's back to small, messy, and inconsistent.

There’s a gap of a few days with nothing worth mentioning, but then we get another interesting window on Monday the 21st of September. The swell is small at 3.3ft from the E, but the wind is glassy again in the morning. The period is very long at 17 seconds – that’s a proper long-period groundswell. For a point break and beginners like Riyue Bay is known for, that long period might cause it to feel a bit fat or straight, but if you get the right bank, those waves will have lovely shape and push. This is a solid option for the learner crew and longboarders, and it’s likely to be a bit less crowded than the big day.

Water temp is sitting at 82.0°F, which feels a bit colder than usual for this time of year (about 2.0°F cooler). Don’t worry, it’s still warm enough for a shorty or just trunks.

So, to sum it up: The clear winner is Wednesday the 16th of September for the experts. The second best, a more mellow and promising option for all levels, is Monday the 21st of September for those glassy, long-period waves. The rest of the window is mostly a dud.

Stay stoked.
