Bonny Hills Surf Forecast and Surf Report

Alright, let’s get this outlook sorted. Rusty here, and I’m looking at the next couple of weeks for Bonny Hills.

First thing’s first – the water temp is sitting right on 67°, which is bang on average for this time of year. Nothing unusual there.

The next few days are pretty ordinary, to be honest. Thursday arvo has a tiny 2 ft swell from the SSE, but with a clean offshore westerly wind, it’ll be small and gutless. Friday morning is the pick of the early period – glassy conditions with a 3 ft S swell, but it’s short period at 7 seconds, so nothing with real punch. The combined energy is weak (111). Still, it’s clean.

From Friday afternoon right through to Sunday the 6th, the wind swings onshore or cross-shore, and the surf quality turns poor. There’s a bump on Saturday arvo to 4 ft but from the NE with a 5-second period – that’s just wind slop. Not worth paddling out for.

Monday the 7th morning has a 5 ft S swell (10-second period) and light cross-shore winds, but the combined energy is moderate (395), and the conditions are only marginal. Tuesday the 8th morning sees a 7 ft SSE swell with an 8-second period and moderate energy (595), but it’s cross-shore and choppy. That’s getting too big for beginners and still not clean.

Wednesday the 9th morning is glassy again with a 3 ft SE swell – another clean but small window. The real standout comes on Thursday the 10th afternoon. That’s a 4 ft SSE swell, but with a phenomenal 22-second period – that’s a very long period groundswell. The combined energy is very strong (2247). The wind is moderate cross-shore, so it’s not perfect, but the energy is massive. This is one for experienced surfers looking for power.

The true highlight of the whole forecast is Friday the 11th morning. We’ve got a 7 ft SSE swell, 12-second period, and a clean cross-offshore wind from the SW. The combined energy is strong (1323). This is a serious, powerful swell with clean conditions. The swell direction (SSE) is off the optimum SE direction, but it’s still a solid, well-shaped wave. It’s strictly for experienced surfers at this size. Crowds are “sometimes” at Bonny Hills, so you might have some company, but it won’t be a madhouse.

After that, the surf drops back. Sunday the 13th morning is glassy again but tiny at 2 ft, with a long 17-second period (312 energy). It’s clean but small. The rest of the second week is mostly a write-off – onshore winds, short-period junk, and poor conditions. Thursday the 17th afternoon has a 5 ft SSE swell with a clean offshore WNW wind (294 energy), and that’s a decent little window for a session, but it’s nothing like the 11th.

The gap between the standout on the 11th and the small window on the 17th is about 5 days of mostly poor, marginal, or onshore conditions. The second week is thin pickings overall.

So, bottom line: if you’ve got one session to chase, make it the morning of Friday the 11th of September. That’s the big one. Long-range stuff around the 17th is promising but less certain.

Rusty.
