The Lowdown
Alright, mate, let’s talk about Chapadmalal. This is a point break that’s pretty consistent and loves a swell from the SSE, which is exactly what we’re seeing. The water’s sitting at 51°F, which is a good 4°F above the usual for this time of year—so it’s a bit warmer than normal, which is a nice bonus. The first week is a bit of a mixed bag, but there’s one session that’s going to be a true standout.
Sunday, August 9th is a total write-off. Strong winds from the WSW at 25 mph, cross-offshore, but the swell is junky and the conditions are just poor. Don’t even think about it.
Monday, August 10th morning is still marginal with a cross-shore breeze and a chop. The afternoon, though, gets interesting. Swell jumps to 8ft from the SSE with a long 12-second period, so proper groundswell energy (combined energy of 2885). The wind is cross-shore, but the problem is this is too big for a beginner-friendly point—it’s going to be a big, powerful wave for the experienced crew only.
Tuesday, August 11th morning is the real highlight. You’ve got 7ft from the SSE at 11 seconds, a light offshore wind from the W at 6 mph, and the conditions are clean. Combined energy is 1335, which is solid. This is excellent for experienced surfers—clean, lined-up waves on the point. Crowds are possible, so get there early.
Wednesday, August 12th morning is glassy perfection. Swell drops to 5ft from the SSE with a 10-second period, but the wind is dead calm—0 mph from the NNW. Absolute glass. Combined energy is 704, so it’s not huge, but the quality will be smooth and fun for everyone. The afternoon brings a 5ft swell with a very long 14-second period, but it goes onshore from the SE at 6 mph, which will make it a bit messy.
Thursday, August 13th through to Saturday, August 16th morning is a flat spell. Swell drops below 5ft, winds are mostly cross-onshore, and the energy is weak (under 350). Nothing worth paddling out for.
Sunday, August 16th afternoon shows a little life. Swell is 5ft from the E with a short 7-second period, but the wind is light offshore from the NNW at 3 mph, keeping it clean. Combined energy is only 260, so it’s small and weak, but if you’re keen for a short session, it’s rideable.
Monday, August 17th is another day of big, messy surf. Morning has 8ft from the ESE but cross-onshore winds and choppy conditions. The afternoon hits 10ft from the SE at 8 seconds—combined energy 1035—but it’s too big for this break and the wind is cross-shore. Kite surfers might love it, but paddlers should stay away.
Tuesday, August 18th is clean and surfable. Morning brings 7ft from the SE at 9 seconds with offshore NW wind at 16 mph, giving clean lines. Combined energy 852. The afternoon drops to 5ft with cross-offshore wind, still clean. Not a standout, but a decent session.
Wednesday, August 19th onward the swell fades hard. From 2ft to 5ft, with weak energy under 170, and winds are mostly cross-offshore but not enough swell to push anything. The last true standout is on Monday, August 24th. Morning has 7ft from the SSE at 11 seconds, offshore NW wind at 16 mph, and combined energy of 863. The afternoon is similar with 7ft and light cross-offshore wind. This is the best of the long-range window—clean, solid groundswell, and the point will be firing. It’s a week and a half away, so keep an eye on it, but it looks promising.
Overall, the best session is Tuesday morning, August 11th—clean, solid 7ft, offshore wind, and the point running. The long-range highlight is Monday, August 24th for a similar setup. The rest is either blown out, too small, or too big. Stay patient.

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