The Lowdown
G’day, Rusty here, lookin’ at what’s on the cards for Riviera Shorebreak. Straight up, it’s gonna be a lean, quiet run. This spot rarely breaks anyway, so a blank stretch ain't exactly a shock—but even for here, it’s a long slog with almost nothing worth paddlin’ out for.
The whole first week, from Sunday the 16th right through to the end of the week, is pretty much a write-off. We’ve got small swell—around 2ft to 4ft from the SW—but the wind’s all over the shop. Most mornings and afternoons are cross-on or onshore, chopping things up, or it’s dead calm but the wave quality is just poor. Combined energies are weak to moderate (mostly between 196 and 495), and the period hangs around 13 to 15 seconds, so there’s some groundswell in there, but it’s not enough to save it. The water’s sitting at 89°—a touch warmer than normal for this time of year, which is notable, but it doesn’t help the surf.
Monday the 17th afternoon sneaks in a bit of offshore wind from the NE, but it’s rated marginal with questionable tide, so don’t get your hopes up. That’s about the only glimmer in the first ten days.
Then we hit a proper dry spell. From Tuesday the 25th morning, there’s a brief flicker—clean conditions, light offshore from ENE, tiny 2ft SW swell with a very long period of 16 seconds. Combined energy is moderate at 297. That’s about the best we see for the whole outlook, but it’s small and inconsistent. After that, it’s back to poor surf or marginal calls all the way through to Monday the 31st.
The very end of the run, around Friday the 28th and Saturday the 29th, the swell bumps up a bit—3ft to 4ft, SW direction, period 16 seconds—and combined energy climbs to moderate-strong (517 to 719). But the wind stays cross-on, choppy, and all those are rated poor or marginal at best. For a spot that’s already rarely breaking, it’s just not coming together.
Look, if you’re desperate, that Tuesday the 25th morning window is the only nod of the head I can give—tiny, clean, but it’s there. Otherwise, the forecast is a long quiet stretch. It tends not to stay this poor forever, and things can change, but right now, it’s a waiting game.
Rusty.

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.
