Alright folks, Rusty here with a look at our local surf. Let's get into it.

First up, the water temperature is sitting pretty at 84°, which is about average for this time of year, so no surprises there.

We’ve got a rough start, honestly. The next few days are a write-off. Sunday the 5th and Monday the 6th are just no good – windy, messy cross-shore breezes whipping up a cross-chop. The swell is all over the place, weak and short period, with wave energy barely cracking 130. Not worth paddling out. This poor run hangs around right through until Thursday the 9th. Even though the swell gets a boost in period on the 9th, it’s tiny and the wind is still a problem.

Now, Friday the 10th of July is where things start to twinkle. The morning is still a bit iffy, but by the afternoon we see a real shift. The wind swings to a light cross-offshore breeze out of the WSW, cleaning things up nicely. The swell comes in from the ESE with a very long 18-second period, and the energy jumps up to 1257. That’s proper groundswell. This setup is a dream for a point break like Riyue Bay (Riyuewan). That long period stuff likes to wrap around points, so we could see some nice lines. Expect waves around 4ft. It won't be huge, but the quality should be there.

Saturday the 11th keeps that promise going. More of that lovely long-period E swell at 4ft, with clean conditions and a gentle cross-offshore breeze. The energy stays high at 1151. This could be the pick of the weekend. Keep in mind the crowds, which can show up sometimes here.

We then slide into a bit of a mixed bag through the middle of next week. Sunday the 12th sees the swell drop in period and the wind picks up again. By Tuesday the 14th, things clean back up nicely. We’ve got a light breeze and a clean swell from the SSE around 5ft. It’s nothing special, but it’s surfable.

The real hidden gem might be Wednesday the 15th. The afternoon goes glassy – dead flat calm wind – with a clean 4ft S swell. That’s as good as it gets for a clean, user-friendly wave. Energy is a modest 271, but the conditions will make it feel a lot better.

Looking further out, the second week is quieter. There are a few glassy mornings on the 16th and 17th, but the swell is on the small side at 3ft to 4ft. The 18th has some potential with a glassy afternoon and a spike to 6ft, but that swell has an awful period of just 5 seconds, which means it’s going to be weak and bumpy. Not worth getting excited about.

So, for the standout day? If you can, make it for the afternoon of Friday the 10th or the morning of Saturday the 11th. That’s your best window for quality. The Wednesday afternoon glass-off on the 15th is a stellar backup for a peaceful, clean session. The rest of the window is either poor or just ordinary.

Stay frothy,
Rusty

A general guide to surfing at Riyue Bay (Riyuewan) can be found by selecting the local surf guide option on the grey menu. Our Riyue Bay (Riyuewan) surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period.

Further information to help with frequently asked questions about our surf forecast for Riyue Bay (Riyuewan) may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
