The Lowdown
Alright, I’ve got a look at what we’ve got coming down the line for Bonza Bay. It’s a tough stretch, I gotta be honest. The forecast is full of messy winds, cross-chop, and poor surf quality for most of the next few weeks. This is one of those runs where you’re gonna be checking the cam a lot more than you’re waxing up.
The pattern for the whole period is dominated by onshore and cross-shore winds. We get a little pulse of swell here and there, but the wind just won’t play nice. There are long gaps, days on end, where the conditions are just plain ugly. The best we can hope for is a short window of clean, glassy surf, and that’s about a week and a half away.
Right now, from Sunday the 9th of August, the surf is a write-off. The wind is howling from the WSW at 12 mph, cross-offshore, with a 4ft SSW swell at a decent 14 seconds. The combined energy is moderate at 632, but the conditions are marginal at best. By Sunday afternoon, it goes completely south with 25 mph S winds and a big, messy 10ft S swell. That’s too big and blown out for anything fun.
Monday the 10th is more of the same. A 5ft SSW swell on Monday morning, but the wind is a cross-shore SW breeze, making it choppy. The whole first week is just a grind of cross-on winds and poor surf. The swell energy peaks on Tuesday the 11th with a 7ft SSE swell and a combined energy of 1582, which is moderate to strong, but it’s cross-on from the ESE at 12 mph. It’s not worth paddling out for.
There’s a small break on Wednesday the 19th of August. That’s the one to circle on the calendar. The morning shows a glassy, calm sea with a 3ft E swell. The wind is nothing, a glassy calm. The combined energy is weak at 218, but the wave comment says “expect good surf conditions.” That’s the standout. It’s not big, but it’ll be clean as a whistle. If you want a longboard or a funboard, that’s your morning. The water temp is about average for this time of year, so nothing weird going on there.
Before that, on Monday the 17th, there’s a glimmer. A 5ft E swell with a period of 11 seconds, and the wind is light from the S at 3 mph. It’s cross-on, but with that light air, it could be clean. It’s worth a look. The combined energy is moderate at 621.
After the 19th, we get a bit of a pulse again on Thursday the 20th with a 5ft SSW swell in the morning, cross-offshore from the WSW at 19 mph, making it clean. But the wind is fresh, and it’s a bit of a battle. The afternoon blows up with a 7ft SSW swell and strong cross-onshore winds. Not great.
So, the honest call is this: the whole period is mostly a no-go for a decent paddle. The only real standout is the glassy Wednesday morning on the 19th. If you’re desperate, maybe the Monday the 17th morning could be okay. Otherwise, it’s a long wait. For the rest, with the strong winds and messy surf at a beach setup, this is looking a lot more like a kite surfer’s playground than a surfer’s dream.
Stay patient, keep an eye on that Wednesday.

Information about the Bonza Bay Surf forecast
The above surf forecast table for Bonza Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bonza Bay can be found by selecting the local surf guide option on the grey menu. Our Bonza Bay surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Bonza Bay) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Bonza Bay may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
