Bonny Hills Surf Forecast and Surf Report

Alright, mate. Rusty here, and I’ve got the story on our local stretch. The next couple of weeks are a real mixed bag—nothing that’ll blow your mind straight away, but there are a few windows where it all comes together. We’ve got a few flat spells to sit through, but stick with me.

Right now, we’re looking at a pretty slow start. The first real chance of a paddle doesn’t come until Wednesday the 26th, and even then it’s a quiet one. Bonny Hills is the only break worth talking about, and it starts off a bit rough—Tuesday afternoon (25th) is a write-off with a messy 6ft NE windswell and a 25 km/h cross-breeze chopping it up. The energy is weak at 294, so don’t bother.

Come Wednesday morning (26th), things perk up. The wind drops to glassy—5 km/h from the NW, and that’s a huge positive. The swell is a clean 5ft from the NE with a period of 8 seconds. The combined energy is still modest at 243, but it’s surfable and clean. Water temp is sitting at 67°, which is about average for this time of year—nothing wild there. This is your best bet for the start of the week, but it’s a small, gentle wave—fine for a longboard or a beginner’s session.

We hit a bit of a lull from Thursday afternoon (27th) through to Friday (28th) morning, with some okay moments, but nothing that screams ‘drop everything.’ Thursday morning (27th) has a 6ft S swell with a solid 604 energy reading, but it’s cross-shore and tricky. The real standout window opens up on Friday morning (28th): glassy conditions again, a 4ft S swell, and a 9-second period. The energy is 338, and the wind is near nothing. That’s a clean little morning surf.

The pattern continues into the weekend, but Saturday (29th) and Sunday (30th) mornings offer the best chances. Sunday morning (30th) is particularly clean—cross-off winds from the SSW at 15 km/h on a 4ft SSE swell. The energy is 307, and it looks clean. But you have to be out early before the afternoon wind kicks up.

Now, here’s the one that really catches my eye. Monday morning (31st August). Bonny Hills is going to see a 4ft SSE swell with a very long period of 17 seconds. That’s proper groundswell energy, and the combined energy is a strong 951. You’ll feel that pulse. The wind is light cross-shore from the south at 10 km/h, so it’s not glassy but it’s clean enough. That long period means the wave will have shape and power, and being a point break, it’ll handle that direction well. This is the pick of the whole forecast—if you can get out that morning, do it. The crowd factor is ‘sometimes’ at Bonny Hills, so expect a few locals out but nothing crazy.

After that, the second week is quieter. Tuesday (1st September) morning has a clean 4ft SSE swell with offshore winds, but the energy drops to 346. Nothing special but a fun surf. The rest of the week shrinks down: by Thursday (3rd) and Friday (4th), we’re looking at tiny 1ft to 2ft swells with very low energy (85 to 104). It’s nearly flat, with a few glassy moments for a micro-session.

The last gasp of decent swell comes early in the second week: Monday morning (7th September) has a 4ft SSE swell with clean cross-off winds and an energy of 335. The afternoon (7th) sees a 4ft SSE swell with a 20 km/h offshore from the WNW, giving you a clean, lined-up wave. That’s a good one for an afternoon session. After that, Tuesday (8th) is small but glassy—3ft SSE swell, 11-second period, and still air. A tiny, clean point wave to end the run. By Wednesday (9th), it’s all over with strong 25 km/h winds and messy surf.

So the standout is clear: Monday morning, 31st August at Bonny Hills. That long-period groundswell with clean winds is your best chance at something memorable. Get out there if you can.

Rusty.
