The Lowdown
Alright, Rusty here again, breakin’ it down in feet and Fahrenheit for ya. We’ve got a solid 16-day stretch ahead, but it’s a slow burn with one morning that’s gonna be burned into your memory.
The pattern kicks off with a moderate, long-period groundswell from the SW that gets going Sunday morning the 16th. It’s all about Quatro-Once (411), a consistent point break that loves this direction. The water’s at 85°, which is a touch warmer than normal for the season – no wetsuit needed.
Sunday morning the 16th is the absolute standout for the whole first week. We’re looking at a clean 4ft SW groundswell with a 15-second period. The energy is moderate (729) and the wind is glassy – dead calm. The conditions are predicted to be very good. This is a beginner-friendly point with long, peeling lines. It’ll be clean as a whistle. Expect a crowd, though; this spot sees ’em sometimes, and this kind of quality will pack the lineup.
Monday morning the 17th keeps it clean with a light offshore breeze from the N and similar 4ft SW swell. The energy jumps to a strong 1141, so there’s more push behind those waves. It’s rated excellent for experienced surfers, so the rippers will have a field day.
Through the rest of the first week, the swell slowly fades into the 3ft range, with clean, glassy mornings. The afternoons get a bit messy with cross or onshore breezes. Then on the 23rd of August, the swell drops to just 2ft, but the period goes to a massive 20 seconds! It’s super long-period, meaning glassy, tiny lines perfect for a longboard. The energy is moderate (464), so it’s all about finesse.
The second week from the 24th onward is much smaller, with waves around 2ft to 3ft through the 28th. The period stays long, mostly 15 to 18 seconds, but the energy is low to moderate. Plenty of glassy mornings, but strictly for the loggers.
Saturday morning the 29th is our second big standout, but being over a week out, it’s a promising one to watch. The forecast shows a new SW groundswell building back to a clean 4ft with a 16-second period and very strong energy (759). With zero wind (glassy), this could be another magic morning at Quatro-Once. The same good vibes look to hold into the 30th and 31st with glassy conditions and waist-to-chest high swell. It looks real good, just a little less locked in.
Rusty.

Information about the Quatro-Once (411) Surf forecast
The above surf forecast table for Quatro-Once (411) provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Quatro-Once (411) can be found by selecting the local surf guide option on the grey menu. Our Quatro-Once (411) 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 (Quatro-Once (411)) 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 Quatro-Once (411) 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.
