Avalon-South Surf Forecast and Surf Report

Hey folks, it’s Rusty. Well, looking at the 16-day picture for Avalon-South, it’s a bit of a slow burn for the most part, but there’s some real fire waiting at the end.

The first week or so is pretty flatlined. From Sunday the 9th right through Saturday the 15th, we’re looking at tiny swell—mostly around 1ft to 3ft—with weak energy (often under 100). Winds are all over the place, mostly cross or cross-on, and the conditions are generally poor or just “surfable but ordinary.” Not worth paddling out unless you’re desperate for a splash.

Monday the 16th sees a little bump in swell to 3ft, but the period drops to 6 seconds and the wind kicks up from the southeast, making it choppy. That pattern holds into the 17th and 18th with similar 3.5ft to 5ft swell, but the wind stays onshore or cross-on, and the energy is still moderate. Honestly, it’s still a pass.

Now, here’s where it gets interesting. Thursday morning, August 20th is the first real standout. We’ve got a 6-7ft groundswell from the east-northeast with a solid 9-second period and a massive 1063 combined energy. The wind is light from the southwest—clean and cross-off. That’s your best window for some proper, lined-up waves. It’s a beginner-friendly break anyway, but with this size, beginners should keep an eye on the sets.

Tuesday morning, August 22nd lights up again: 6-7ft from east-northeast, 10-second period, 820 energy, and a light west-southwest breeze keeping it glassy. That’s another session to circle on the calendar. Both of these mornings are the real highlights of the whole outlook.

Other days like the 21st and 23rd have similar swell heights but are mixed with onshore winds or tricky tides, so they’re more marginal.

Water temp is sitting around 63.5°F, which is about 1°F cooler than normal for this time of year—nothing crazy, just a touch cooler than average.

Bottom line: Don’t rush out this first week unless you enjoy frustration. Save your energy for Thursday the 20th and Tuesday the 22nd—those are the mornings where Avalon-South will actually turn it on. Stay patient, and you’ll get your reward.
