The Lowdown
Alright, listen up. Rusty here, giving you the lowdown on what’s cooking.
The water temp is about 70°, pretty standard for the season, nothing out of the ordinary.
We’ve got a slow start. Tuesday the 18th and Wednesday the 19th are a total loss – cross-onshore winds, chunky, weak surf. Thursday the 20th gets a size bump with a 7ft south swell, but it’s short period and blown out by strong winds. A total mess.
Friday the 21st is a tease. A 4ft south groundswell with a 13-second period (moderate energy at 533) comes in, but the cross-shore wind ruins it. It’s a maybe.
Then we get a window. Saturday the 22nd morning, the wind goes offshore from the NW at 15 km/h, and we get a clean 3ft swell from the ENE. It’s only a 7-second period, so it’s small and weak (energy at 191), but it’s clean for a fun, small wave. Crowds can show up sometimes.
Now, Sunday the 23rd brings a monster. A 13ft SSW swell rolls in with a 13-second period, and the energy is a massive 7152. That’s serious power. But the wind is cross-onshore, and the forecast says it’s too big for the spot. Only the proper chargers on big-wave gear. The afternoon drops to 7ft, still heavy, with lighter wind.
The one to save for is Monday the 24th afternoon. The wind goes glassy – dead flat – and we’ve got a 4ft south swell with a very long 16-second period. That’s a proper groundswell with good energy (811). It’s going to be clean, lined up, and offer the best shape of the whole period. The long period means it’ll be a bit more selective at the beach break, but a dream on a point or reef.
After that, it’s a slog. The rest of the week and into the second week is mostly ENE pulses with persistent cross-shore or onshore winds. The 25th is a letdown. The 26th to the 31st is a lot of “marginal” calls with lumpy, wind-affected surf. The energy readings are moderate at best.
The start of September is more of the same – ENE swell, onshore wind. The only clean option is on Monday the 31st afternoon, with a cross-offshore wind and a 5ft ENE swell. It’s a possible session, but not a standout.
So, overall: a pretty patchy 16 days. The standout is the glassy Monday afternoon the 24th. The Saturday morning the 22nd is a smaller, clean option. The rest is a battle with the wind.
Rusty.

Information about the Warner Beach Surf forecast
The above surf forecast table for Warner Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Warner Beach can be found by selecting the local surf guide option on the grey menu. Our Warner Beach 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 (Warner Beach) 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 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. 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.
