10th Street (Avalon) Surf Forecast and Surf Report

G’day, Rusty here. Look, I’m not gonna sugarcoat it—this stretch is flat more than it’s fun. There’s a long spell of nothing before we even see a surfable wave, so keep your expectations in check. Here’s the run-down.

At 10th Street (Avalon), from Tuesday the 25th of August all the way through to Monday the 1st of September, it’s a total dud. Swell is tiny, maybe 1–2 ft at best, and the wind is mostly cross-onshore or choppy. The combined energy is weak—just 30 to 117 range. Not worth paddling out.

The first decent window comes Tuesday morning the 1st of September. Swell is only 1 ft from the SE, but the period is 15 seconds—super long-period groundswell for such a small wave. Wind is light offshore out of the NNE, so it’ll be clean. Combined energy is 68 (still weak). It’s surfable but very ordinary. That afternoon sees similar: 1 ft, 14-second period, light offshore west wind, energy at 117 (weak). Still small, but clean.

Wednesday the 2nd of September morning keeps it going with 2 ft from the SE, 12-second period, light offshore north wind, and 101 energy (weak). Clean but tiny. The afternoon turns cross-onshore, so grab the morning.

Now, the one real size event: Thursday the 3rd of September morning. Swell jumps to 7 ft from the NE, but the period is only 7 seconds—short-period windswell. Energy is 535 (moderate), and the wind is light and cross. That’s a lot of lumpy, close-out energy. For a beach/jetty break, that short period makes it a choppy mess, and it’s really only for experienced surfers—marginal at best. That afternoon sees 7 ft from the ENE at 8 seconds, energy 722 (moderate), but cross-onshore wind. Messy.

From Friday the 4th to Wednesday the 9th of September, it fades back into poor conditions with onshore wind and chop. Swell lingers between 1 ft and 5 ft, but the wind never cleans up, and energy drops from 589 down to 38. Not worth it.

If I had to call it, the Tuesday the 1st of September morning at 10th Street is the pick—tiny but clean, with light offshore wind and long-period lines. For those who want size, Thursday the 3rd of September has waves but only for the experienced, and even then it’s marginal. Water temp is nothing out of the ordinary for this time of year.

There’s a big flat gap at the start, and after that small clean window, it turns poor again. That’s the pattern here—sometimes you just have to wait for a better forecast.

Rusty.
