The Lowdown
G’day, Rusty here.
Alright, let’s cut to it. The next fortnight is a story of two halves: a whole lot of nothing, followed by a few days of serious power. The first week is going to be a struggle, so don’t get your hopes up.
The water right now is running a touch warmer than normal for the season, which is something.
From Saturday through to the next Saturday (the 15th to the 21st), it’s poor. We’ve got a sickening southwest swell around 3-4 ft with a long period, but it’s got a cross-onshore wind on it, making it bumpy and messy. The energy is moderate, but the quality is just not there. It’s a lot of paddling for nothing. The swell stays in that 3 to 4 ft range, with the period dropping a bit, but the wind never gets clean. There’s a lot of “poor” and “marginal” in the notes, and it’s best to just find something else to do.
Saturday the 22nd is still small, but the period gets back up to 16 seconds. Still not enough push.
Then, here’s the one. Sunday morning, August 23rd. The swell jumps up to 8 ft from the SSW at 15 seconds, and the energy is strong – a proper 2577. But the kicker is the wind: it’s glassy. Absolutely clean. This is the standout of the whole window. It’s not for beginners, that’s for sure. That size is going to be thumping, but if you’ve got the skills, this is your moment. The break is exposed, and it rarely breaks, so this is a special alignment.
Sunday afternoon and into Monday, it gets even bigger – pushing 10 ft. The comment says it’s too big for the spot, and that’s the truth. It’s a foamball fest, and you’d be mad to go out unless you’re a name. Later Monday, it eases to around 7 ft but gets a cross-chop, so it’s still heavy and messy.
Tuesday and Wednesday (25th and 26th) the swell backs down to the 4-6 ft range, but the wind swings cross-onshore again, ruining the potential.
Then there’s another massive pulse on Friday the 28th. The energy is off the charts – 4513 – but it’s a huge 10 ft of southwest swell, and again, it’s too big for this break. Plus the wind is onshore. It’s a no-go.
The final weekend (the 29th and 30th) settles down to the 3-6 ft range, with the period mixed. It’s still a bit scratchy with the wind, but it’s rideable for the experienced.
So, the only real standout is that Sunday morning, the 23rd. The glassy conditions with that solid southwest groundswell is the one to be there for. The rest of the big swells are just too much. The first week is dead, so save your energy. That Sunday is your chance.
Stay salty,
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.
