Table - best surf conditions forecast for Riyue Bay (Riyuewan) over the next 16 days.


Right, let's have a look at what's on offer for Riyue Bay over the next couple of weeks. There's a bit of a mixed bag, but there are definitely some windows where it'll be worth getting wet.

The week kicks off with a pretty flat start. Thursday the 9th is a write-off – small, messy, and cross-shore. Not worth paddling out. We've got a couple of days of poor conditions before things start to turn around.

Friday the 10th morning is where we start to see some life. The swell is only 3ft from the east, but that's a 17-second period groundswell, and with a gentle cross-offshore breeze it's going to be clean. The combined energy is moderate at 732, so there's some push behind it. This is a good one for a beginner-friendly point break like this.

Now, the real standout of the whole forecast is Saturday the 11th. Both the morning and afternoon sessions are looking excellent for experienced surfers. We're talking 5ft to 5ft of east-southeast swell, still with that long 17-second period. The wind stays cross-offshore and light, so it'll be clean. The energy jumps right up – the morning shows a strong 1698 reading. This is the best wave energy we'll see, and with the swell direction coming from the east, it's hitting that optimum NE direction nicely for Riyue Bay. This is the one to prioritise.

After that weekend fun, the conditions get a bit ordinary. Sunday the 12th through to the end of the following week shows a lot of smaller swell and mostly cross-off winds, but the energy drops way down and the quality is just "surfable" at best. There's a definite lull in quality for a good four or five days there.

The second week of the forecast starts to look a little more promising again. Monday the 20th and Tuesday the 21st see a decent S'ly swell coming through, around 4ft to 5ft. The wind goes super light, even glassy on Monday afternoon, which will make the surface like a mirror. The combined energy is moderate to strong, around 400-635, so it's got some proper weight. This is a promising run, though it's a bit further out so don't set your watch by it just yet.

Wednesday the 22nd gets bigger (6ft - 6ft) but the wind swings to the NE, which isn't ideal for this spot. And then Thursday the 23rd looks like a glassy, clean morning with a solid 7ft south-southeast swell. That's big enough for this break, and with glassy conditions, it'll be a ripper for the experienced crew. The energy is strong at 617. But remember, that's a long way out, so treat it as a promising hope.

So, overall: Forget the start of the week. For sure punt for Saturday the 11th – that's the clear winner. Keep Monday the 20th and Tuesday the 21st in your diary as a strong possibility, and keep a loose eye on Thursday the 23rd as a potential corker, but don't bank on it yet.
