The Lowdown
G'day, Rusty here.
Alright, lookin' at the charts for the next couple of weeks, and honestly, it's a bit of a mixed bag. We've got a consistent run of small, weak groundswell pulses, but the quality is gonna be a real struggle most of the time. The best bet, and the only real standout window, is gonna be that very last day.
For most of the run, we're dealing with small surf at Riviera Shorebreak. The swell direction is from the SW, which is what the spot likes, but the size mostly hovers around 2ft to 3ft. The energy is low, with the combined swell energy sitting between 155 and 468 (weak to moderate). The water temp is sitting at a very warm 89°F, a touch warmer than normal for this time of year.
From Monday the 10th through to Sunday the 23rd, it's a tough watch. The waves are small, and the wind is almost always a cross-onshore breeze, messing up the surface. We get a few brief windows of offshore wind on the mornings of the 12th, 13th, and 15th, but with swell that small and a period around 16 seconds (a solid groundswell), it's too straight and weak to really get excited about. This spot rarely breaks, so the fact we're seeing swell at all is something, but the conditions are just poor. A few of these afternoons get a bit choppy and could be more interesting for a kite surfer than a paddle surfer.
We then hit a proper flat patch from Monday the 24th morning through Tuesday the 24th afternoon, with nothing worth mentioning.
Then, the one bright spot. On Tuesday, August 25th morning, something clicks. The wind swings around to a cross-offshore breeze from the southeast at 9 mph, which will clean the surface right up. We've got a clean 2ft swell from the SW, with a period of 16 seconds. The combined energy is 230 (weak), but that clean face with a slight offshore will make it the pick of the fortnight. That's your session. The glassy conditions will make the most of that tiny wave. Expect a few others in the water as crowds here are sometimes a factor. After that, it goes back to poor conditions in the afternoon.
That August 25th morning session is it. There's a big gap of several days with no surf before that and then a real flat spot after. It's not much, but it's the only window where you won't be fighting the wind.

Information about the Riviera Shorebreak Surf forecast
The above surf forecast table for Riviera Shorebreak provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Riviera Shorebreak can be found by selecting the local surf guide option on the grey menu. Our Riviera Shorebreak 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 (Riviera Shorebreak) 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 Riviera Shorebreak 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.
