The Lowdown

G’day, Rusty here.

Look, I’m not gonna sugarcoat it – this 16-day window for Riyue Bay (Riyuewan) is a tough one. The forecast is basically a long, drawn-out run of “poor surf conditions” with no real standouts to get excited about. The first solid recommendation doesn’t even kick in until the 15th of July, and even then, it’s a struggle. The swell is small, the period is short, and the wind is almost always cross or cross-off, never that clean offshore we really want. The best you can say is that the water temperature is about average for this time of year, which is something.

For the first week, from Wednesday the 15th through to the start of the next week, we’re looking at weak, short-period swell from the SSE and S. The combined wave energy stays mostly in the weak to low-moderate range (between 79 and 222), but the quality is just not there. The swell height bounces between 3 ft and 5 ft, but with periods of 5 to 8 seconds, it’s all wind swell – crumbly, weak, and lacking any real push. The wind is a constant 12 to 16 mph from the SW or WSW, which is cross or cross-off at best. It keeps the surface a bit messy, with a moderate cross-chop spoiling what little shape there is. The Saturday afternoon of the 18th sees a bump to 5 ft, but it’s a 5-second period, so it’s just a bit of a lumpy mess. Sunday the 19th afternoon has the highest energy of the period at 222, with 5 ft swell from the S, but again, the wind is cross-off, not true offshore. It’s not worth paddling out for.

The second week, from the 23rd of July onwards, things get even smaller. The swell drops to 2 ft to 3 ft, with periods of 6 to 7 seconds. The combined energy falls into the weak range, often below 100. The wind does ease up a bit, with some light breezes from the SSW on the 24th, 25th, 27th, and 28th, but it’s still cross-shore, leaving a slight chop on the surface. The water looks clean on the charts, but there’s just no swell to work with. The morning of the 30th offers a last flicker of hope with a 1 ft, 16-second groundswell from the ESE, but it’s too small and too long a period for this beach-and-point setup to catch. It’ll barely break.

There are no good surf options in this 16-day window. The break is fairly consistent for this area, which means this blank run is a bit of a bummer, but it’s not unusual. The forecasts can change, so keep an eye on it, but for now, I’d leave the board at home.

Rusty.
