The Lowdown
Hey folks, Rusty here. Let’s talk about what’s shaping up at Riyue Bay (Riyuewan). It’s a point break, beginner-friendly, and fairly consistent, but this stretch is going to test your patience.
Overall, the first week is a bit of a write-off. The swell is small, mostly between 3ft and 4ft, coming from the south and southeast with a short period of 6 to 7 seconds. That’s weak, gutless, and the wind is all over the place – onshore, cross-on, cross-shore – meaning the surface is usually a mess. The wave energy is low, sitting between 71 and 162 (weak energy) for most of those days. The models are basically saying “don’t bother.” The first real glimmer comes on the afternoon of Friday, August 7th. There’s a jump in swell to 5ft from the SSE, with a period of 10 seconds, and the wind turns cross-offshore. The combined energy hits 920 (moderate wave energy), and it’s clean. The morning of Saturday, August 8th, has a similar setup with 4ft from the south, but a fresher 16 mph cross-offshore wind keeps it clean. The energy is 406 (moderate). That Friday afternoon and Saturday morning are the only real standouts in the first two weeks – the best on offer, but still not firing.
The middle of the second week brings a long-period groundswell. On Wednesday, August 5th, and Thursday, August 6th, we see swell from the ESE at 18 to 19 seconds with heights around 3ft to 3ft, and energy building from 362 to 951 (moderate to strong). Sounds promising, but the wind is messy cross-shore at 12 mph, so it’s choppy. By Friday, August 7th, the wind goes cross-offshore and the swell is 3ft from the east at 18 seconds, with energy at 910 (strong). That’s a clean, long-period wave, but at a point break like this, that long period could make it break a bit straight. Worth a look if you’re patient.
The rest of the second week, from August 8th to August 14th, is mostly small, south-southwest swell with cross-offshore winds, but the swell stays under 5ft, and the period is short (8-10 seconds). The energy drops back to between 202 and 637 (weak to moderate). The best of that lot is the afternoon of Thursday, August 13th, with a clean 4ft from the SSW at 8 seconds and energy at 269 (moderate). It’s surfable, but nothing to write home about. The water temp is about average for this time of year. Keep an eye on that Friday 7th and Saturday 8th – that’s your window.
Rusty out.
