The Lowdown
Alright, I’m looking at the charts for Warner Beach and here’s what’s cooking.
The next 16 days have a bit of a slow start, with a lot of choppy, wind-affected conditions. The surf quality is suffering for a solid stretch from Thursday 20th of August right through to the end of the month. There’s a lot of cross-shore and cross-onshore wind, making for messy, lumpy conditions. The waves are small too, mostly under 5 feet, and the swell period is short, so the energy is pretty weak. Not much to get excited about. The water temp is sitting at 70°, which is bang on average for this time of year, so no surprises there.
The first real glimmer of hope shows up on Thursday afternoon, 3rd of September. That’s when we get a proper long-period groundswell from the south, 18 seconds, pushing 8 feet. The combined energy jumps to 3536, which is a solid pulse. The wind is light and cross-shore from the ENE, so it’ll be clean. Warner Beach is exposed to the ESE and this south swell should wrap in nicely. That afternoon session is the standout of the whole run. The swell will be sizeable, borderline big for the less experienced, but for intermediates and above, that looks like a real treat.
Before that, there’s only marginal surf on the 27th and 28th of August, with a bit of long-period swell mixed with short-period windswell and cross-shore winds. It’s rideable but not special. On Friday 4th of September, there’s still some decent leftover swell, 6-6 feet from the south, but the wind is up and cross-off, which keeps it clean, but the energy is dropping. Still a solid option if you missed the Thursday.
Overall, the whole 16-day window is a waiting game. The first week and a half is mostly a bust. The best surf by far is the afternoon of Thursday 3rd September. Mark it on the calendar.

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.
