St Agnes Surf Forecast and Surf Report

G'day, Rusty here. Look, I’ll level with you – we’ve got a pretty tough stretch ahead for St Agnes. The next two weeks are mostly full of poor surf conditions, but there are a couple of brief windows that might just get you out of the house.

We start off now, Monday the 31st of August, and it’s ugly. We’ve got a 10ft cross-on swell from the West with a 10-second period, and the combined energy is a massive 1581 – that’s strong stuff – but the 35 km/h cross-on wind from the NW is absolutely wrecking it. The water temperature is sitting at 65°, which is a touch warmer than normal for this time of year, but that won't help the mess. It’s just lumpy and poor. That continues through Monday afternoon and into Tuesday and Wednesday with smaller, but still messy, swell.

We get a bit of a cleaner look from Wednesday the 2nd of September afternoon through Thursday the 3rd, with a 5ft to 6ft swell from the WSW, cross-off winds, and a 7-second period. The energy drops to the 300s, so it’s moderate, and the waves are clean. It’s not great, but it’s the best we’ve seen. Still, the scores are low, and it’s a very ordinary setup. That cleaner window fades into Friday and Saturday with more cross-on wind and a rising period up to 12 seconds, but the swell is tiny – 4ft or less – and the energy drops to 488, so it’s marginal at best.

The real bright spot, and the only one I’d call a standout, is Sunday the 6th of September. It’s a small day, with a 2ft West swell and a 9-second period, but the wind turns offshore from the SSE at 25 km/h. That means clean, glassy faces at St Agnes. The energy is only 67, so you’ll be scratching for a wave, but if you’ve got a log or a fish, you’ll find a couple of fun ones with no crowd hassles. It’s the cleanest conditions of the entire run.

After that, it’s a long, dry gap. Monday the 7th is almost flat with just 0.3ft and a choppy onshore wind, and then we get a pulse of 5ft on Monday afternoon from the WSW with a 11-second period, but the wind is onshore again. The energy spikes to 644, but the wind spoils it. Tuesday the 8th and Wednesday the 9th see smaller, messy swell again, with scores staying low. Thursday the 10th through Friday the 11th is similarly poor – lumpy, cross-on, and not worth paddling for.

We then get a brief taste of hope on Saturday the 12th and Sunday the 13th of September. Both mornings have a small 2-3ft West swell with moderate offshore wind from the SE and SSE. The energy is in the 100-150 range, so it’s weak, but the waves are clean again. You might get a few knee-high runners if you’re patient. It’s not a day to call in sick for.

The final standout appears on Monday the 14th and Tuesday the 15th of September. This is the biggest swell of the whole outlook – 10ft on Monday morning and afternoon, building to 10ft again, with a 9-second period and cross-off winds from the SW. The energy jumps to 1324 and then 1545, so it’s very strong. This is solid, powerful surf. However, at 10ft, it’s only for experts. The crowds are likely here, and the break is fairly exposed, but with those cross-off winds, it will be a proper heaving lineup. Tuesday the 15th drops to 7ft with an 11-second period, which is still only for experienced surfers. It’s clean, but it’s not a beginner’s day.

The rest of the run tails off into small, messy, or onshore crud. All up, you’re looking at a lot of flat or poor days with only a few short, clean windows. If I had to pick the single best time to paddle out, it’s Sunday the 6th of September morning for the clean, offshore glass, or Monday the 14th for the big-wave crew.

Rusty.
