The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Warner Beach.
It’s a pretty quiet start, with nothing really worth paddling out for. The first couple of days are a write-off, with a strong cross-onshore wind on Thursday morning making a mess of a 7ft south swell. That combined energy is sitting at a moderate 627, but it’s just lumpy and poor. The water temp is 71°, which is pretty much bang on average for this time of year.
We’ve got a bit of a wait, but the first real glimmer of hope shows up on Friday morning, the 21st of August. It’s not a classic, but it’s the best of a bad bunch early on. A 4ft south swell, but with a long 13-second period, carrying a moderate 542 combined energy. The wind is light and cross-shore, so there’s a bit of chop, but it’s surfable. The guidance says Warner Beach is fairly consistent and picks up an ESE swell best, so this south swell isn't ideal, but it’s something.
The standout in this whole 16-day window is a bit of a long shot, and it’s a weird one. Look at Saturday afternoon, the 22nd of August. The data shows a sweet 4ft south swell, but with a very long 16-second period, and the combined energy climbs to a strong 856. The wind is a strong cross-onshore though, so it’ll be messy. But hold on… the real kicker comes later. Keep an eye on Monday morning, the 31st of August. The swell is 6ft from the SE at 7 seconds, but the energy is a massive 1176. By Monday afternoon, it’s 7ft from the ESE, with a huge 1176 combined energy. That’s proper strong. The wind is a fresh cross-shore, so it’ll be lumpy and challenging. This is expert territory. Over 8ft on the 1st of September as well, with a massive 1695 combined energy. The wind is strong cross-onshore though, so it’s a messy, powerful ocean. Not for the faint-hearted.
After that, things settle down into the first week of September. There’s a consistent run of moderate cross-shore winds and waist-to-chest high swell from the E and ENE, but the periods are short and the conditions are marginal. It’s a bumpy, choppy mess at best.
To be honest, the whole run is pretty average. The wind just doesn’t play ball for clean, glassy conditions. If you’re desperate, Friday morning the 21st is your best early bet for a grovel. For the big dogs, keep an eye on the 31st of August and 1st of September, but only if you’re happy with a battle. The setup looks more interesting for kite surfing than paddle surfing on most days.
Rusty.

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 Warner Beach 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.
