The Lowdown
Alright, Rusty here again, but in the old measurements. Let's talk about Riviera Shorebreak for the next couple of weeks. It's a mixed story – we have some swell coming through, but the wind is going to be a problem for many days. You'll need to pick your moments.
We kick off on Friday the 21st with a small 2ft swell from the SW, but the cross-on breeze makes it a total mess. Same story through the weekend and into the start of the week. The swell gets a bit bigger, but the wind direction just ruins the surface. The water temp is about 88°, which is a touch warmer than normal for this time of year.
The first real highlight is Tuesday the 25th. The morning shows some promise with 4ft from the SW and solid wave energy. But it's the afternoon that’s the winner – the wind goes glassy, and we have 3ft of SW swell with a 16-second period. That’s a long-period groundswell, and with the glassy conditions, it'll be clean. This is the best bet of the first week. Just a note: with that long period (16s), it can straighten out a bit at a beach break, but Riviera Shorebreak is the spot for it.
We then hit a choppy patch with poor surf, though the swell hangs around.
Moving into the second week, Monday the 31st of August morning looks good. We have 3ft of SW swell with a light offshore breeze from the NE. Clean conditions and a decent push makes this the other standout for a dawn patrol.
After that, the wind goes cross-off or cross-shore. The swell stays in the 3ft to 4ft range, but the surface gets lumpy. The wave energy is moderate to strong, reaching 752 by Wednesday the 2nd of September, but the cross-shore wind creates chop.
The tail end of the forecast, around the 5th of September, still has 4ft to 4ft swell with 15-second periods, but the wind is light cross-onshore, keeping the quality marginal. The energy is still high, so there's plenty of water moving, but the surface isn't clean.
So, to sum it up: keep your eyes on Tuesday the 25th afternoon for that glassy session, and Monday the 31st morning for clean offshore conditions. The rest of the time, it's a waiting game.
Stay sharp.
Rusty.

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.
