The Lowdown
Alright folks, Rusty here. Let’s talk Chapadmalal.
First off, the first week and a half is gonna be a real grind. There are some clean, small waves here and there, but nothing with any push. Don’t get your hopes up til we get into the second week. The one time that really grabs my attention is around Wednesday, September 9th.
From Friday the 28th through the end of August, we’ve got tiny surf, 2 to 3 feet. The wind does go glassy or offshore, so it’s clean, but the energy is weak – readings are between 25 and 117. This dribble carries on into September. The 1st and 2nd are a total wash with messy cross-shore breezes.
Then we hit Wednesday, the 9th of September. The morning shows a bump to 6 feet from the SSW, with a good cross-off breeze from the NNW. The energy is moderate around 263, but the surf is still marginal. The *afternoon* though, that’s the one. Swell hits 7 feet from the SW, with a moderate offshore wind from the NW. The energy climbs to 613, giving it some real punch. Keep in mind, for a beginner-friendly spot like Chapadmalal, 7 feet is pushing into expert-only territory. The water temp? No anomaly given, but you’ll be in that chilly late-winter water.
The One to Chase: Wednesday, September 9th afternoon at Chapadmalal. You’re looking at clean, offshore lines with a solid 7 foot SW swell. This one’s for the crew who can handle a bit of size, as the offshore wind is gonna make for some beautiful, peeling waves.
Thursday the 10th sees a massive 8 foot S swell, but the cross-onshore wind will wreck it. After that, the swell fades and the wind turns nasty again through the weekend.
Bottom line: save your energy for that Wednesday afternoon the 9th. The rest is a waiting game.
Rusty.

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.
