The Lowdown
Alright folks, Rusty here. We’ve got a solid run of swell on the horizon for Quatro-Once (411). This is a beginner-friendly point break that’s exposed to the SSW swell, and it’s looking like a great little window for the crew who want clean, manageable waves. The water is a touch warmer than normal right now, sitting at 85°.
The action kicks off Tuesday afternoon, August 11th, with a 4ft SSW swell rolling in. The combined energy’s sitting at a moderate 956, but the wind is cross-on from the WSW at 6 mph, so it’s a bit of a scratchy start. Conditions are marginal, so you might want to wait.
Wednesday morning, August 12th, is where it gets interesting. The wind swings to the SE at a glassy 3 mph, and we’ve got a 3ft SSW groundswell with a long 16-second period. The energy is 739 – still moderate – but that glassy surface means the waves will be clean and lined up. This is a standout session for the week. The afternoon is glassy again with a similar 3ft SW swell, but the wind shifts to a light SW. Still a great option.
Thursday morning, August 13th, the swell drops to 2ft from the SSW, but the wind is glassy from the NE. It’s small but clean. The afternoon picks up a little with a 2ft SW swell and a light offshore breeze from the NNE at 6 mph. Conditions are clean.
The next real highlight is Friday morning, August 14th. The wind is dead calm, glassy as can be, with a 4ft SW swell and a period of 18 seconds. That’s a very long period groundswell, which this point break will love. The combined energy is 853 – moderate but with that period, expect some nice, powerful lines. The afternoon gets a bit bigger at 4ft, but the onshore wind from the SW at 6 mph messes with the quality.
Saturday morning, August 15th, is the best on offer for the whole run. The swell is 4ft from the SW with a 16-second period, and the combined energy jumps to 1075, which is strong. The wind is glassy from the S at 3 mph. This is excellent, punchy surf for experienced surfers. The waves will have real push. The afternoon stays at 4ft but the wind goes cross-shore from the W, making it a bit messy.
Sunday, August 16th, is a write-off. The onshore wind picks up, and the quality drops out. Monday morning, August 17th, is a return to form: dead calm with a 4ft SW swell, 14-second period, and moderate energy of 559. Glassy and clean.
The rest of the week into the following week stays small but consistent. Tuesday morning, August 18th, has a glassy 4ft SW swell. Wednesday morning, August 19th, is clear and glassy with a 3ft SW swell. The energy is moderate, around 599. Thursday and Friday, August 20th and 21st, drop to 3ft and 3ft, but still glassy in the mornings. The weekend of August 22nd and 23rd brings a little more swell, with a 3ft SW groundswell on Saturday morning and a 3ft SW swell on Sunday morning with a cross-offshore breeze from the NE. The period on Sunday afternoon hits 19 seconds, which is very long, but the swell is only 2ft. The last real pulse is Monday, August 24th, with a 2ft SW swell and an 18-second period, but it’s glassy. After that, it fades out.
So, the standout is without a doubt Saturday morning, August 15th. That 4ft SW groundswell with glassy conditions and strong energy is the pick of the bunch. The early mornings of Wednesday, August 12th, and Friday, August 14th, are also cracking calls. Crowds are possible at Quatro-Once, so get in early for the cleanest waves.
Rusty.

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.

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.

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.
