The Lowdown

Alright, Rusty here. Let's have a look at what we've got coming down the line at Belt Road.

First off, it's a reef break for advanced surfers only, and it's inconsistent, so you gotta pick your moments. The water temp is sitting at 58°F, which is about normal for this time of year.

The next week and a half is a real mixed bag with a lot of junk in between the good stuff. Thursday the 6th and Friday the 7th are basically write-offs with tiny, gutless swell and poor conditions. Saturday the 8th sees a bump in size to 5ft, but the period is a short 8 seconds and it's cross-onshore and choppy, so not worth the paddle. Sunday the 9th gets huge—13ft from the NW—but with a howling 19 mph cross-on wind and heavy rain, that's just a washing machine. Not for paddle surfing; that’s a kiter’s dream.

Then we get a bit of a reset. Monday morning, August 10th is a standout. We've got a clean 4ft swell from the WSW with a long 16-second period, and glassy offshores from the SSE at just 3 mph. The combined energy is a solid 936 (moderate). It's not huge, but the quality will be there on the sets. The conditions will be clean and lined up. Just remember, it’s an advanced reef break and it can be inconsistent, so patience is key. Crowds are possible here.

That nice spell holds into Tuesday morning the 11th with clean 3ft surf and cross-off winds, but it fades quickly in the afternoon.

Wednesday the 12th through Thursday the 15th is a messy period of building but unruly swell. The wind is all over the place—onshore, cross-onshore, or howling—so the wave quality is going to be poor. On the 15th, we see 13ft waves but cross-shore winds are making a mess of it.

Now, for the second week, the real prize looks like Sunday morning, August 16th. We are looking at a solid, long-period groundswell of 10ft from the WSW, but the real winner is that glassy, no-wind morning. The energy is huge at 4144 (strong), so this is for experts only, but if you can handle it, the reef will be firing with clean, heavy walls. Paddling out between sets won't be a problem with that long period.

Monday the 17th repeats the trick with 10ft and clean offshores at 3 mph. Another cracker for the experienced crew. The energy is still very strong at 2971.

After that, the swell starts to drop back down through the 18th and into the 19th with cleaner, more manageable conditions on the mornings but smaller surf. By Thursday, August 20th and Friday, August 21st, we get clean 5ft to 3ft waves with a good 14 to 17-second period and offshore winds, which will be a nice way to finish the run, though the energy drops off a bit.

So bottom line: The pick of the lot is Sunday August 16th and Monday August 17th for big, clean, glassy groundswell for experts. The early window is a dud. The mid-period is messy. The last few days of the run offer nice, clean long-period rollers for the more moderate crew.

Rusty.

Information about the Belt Road Surf forecast

The above surf forecast table for Belt Road provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Belt Road can be found by selecting the local surf guide option on the grey menu. Our Belt Road 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. If you surf the same spot (Belt Road) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Belt Road 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.
