The Lowdown
Alright folks, Rusty here, and I’ve been chewing through this forecast for our coast. Gotta be honest with you—this is a rough 16-day stretch. We’re looking at Riviera Shorebreak as the only spot on the menu, and most of the time, it’s not looking good. The surf is small and the winds are mostly onshore or cross-onshore, leaving things messy for long periods.
The water is a balmy 89°F, which is much warmer than usual for this time of year - you’ll feel it when you paddle out on Sunday.
We start on Sunday afternoon (9th August) with a tiny 3 ft swell from the SW, period at 14 seconds. There’s some energy (382 units), but the risk of thunderstorms and a light cross-shore breeze kills it. It’s marginal at best.
From Monday (10th August) all the way through to Thursday morning (14th August), it’s pretty bleak. The swell hangs around 2 ft to 3 ft, mostly from the SW, but the wind is constantly cross-on or onshore. The wave energy bounces between moderate and dropping (363 to 587), but the conditions are listed as “poor” or “marginal” every session. Nothing worth your time.
Now, Thursday afternoon (14th August) is the one gem. Swell hits 3 ft from the SW, period at a long 18 seconds, and the combined energy jumps to 771 (moderate). The wind turns cross-offshore from the NNE with a light breeze, and the guide says “expect very good surf conditions.” This is the clear standout of the whole forecast. Clean lines, solid long-period groundswell. It’s still small, but if you hit it right, it’ll be the best you’ll see.
After that, it falls apart again. Friday 15th through to Tuesday 19th August is mostly poor with onshore winds, small swell, and low scores. The energy drops back to the 300s and 400s.
Saturday 22nd August afternoon shows a little light – a tiny 2 ft swell but with a cross-offshore wind and clean conditions. Expect decent shape, but it’s knee-high at best.
There’s one more flicker on Monday 24th August afternoon – same small 2 ft SW swell, period 17 seconds, and a clean cross-offshore breeze from the NE. Surf will be small but tidy.
Overall, if you’ve only got one session, make it Thursday 14th August afternoon. The rest is mostly a bust. For a break that rarely breaks, this is a tough stretch. Keep watching the charts – things can turn.
Rusty.

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.
