The Lowdown
G’day, I’m Rusty, and here’s how the surf’s looking for Bonza Bay.
We’ve got a slow start, then a real mixed bag over the next couple of weeks. The first proper session worth paddling out for is on Tuesday morning, July 21st. The water’s sitting at 64°, which is much colder than usual for this time of year – about 4° below average, so you’ll want a thick wetsuit.
Tuesday morning, the 21st, is your first standout. Bonza Bay is a river mouth, and it’s showing a clean 4ft SE swell with a period of 11 seconds, glassy conditions with a light SSE breeze. Combined wave energy is moderate at 671. It’s fairly consistent here, and with the wind glassy, the waves will be clean and lined up. A solid session for intermediates.
The next real highlight is Saturday morning, July 25th. We’ve got a 5ft S swell, period of 15 seconds – that’s proper groundswell – and again glassy conditions with a light SSE breeze. Combined energy is moderate at 997. The longer period will give you some real push, and with the river mouth setup, it should hold that shape nicely. Still intermediate-friendly.
Then, keep an eye on Wednesday morning, July 29th. That’s a week and a day out, so a bit less certain, but it’s looking excellent for experienced surfers. A 6ft S swell, 15-second period, combined energy at 1565, with light NNE cross-offshore winds keeping it clean. That’s a solid, powerful swell – not for beginners, but if you’ve got the chops, it’s worth the paddle.
There are a few gaps in between where the wind gets messy or the swell is too small or blown out. Thursday and Friday the 23rd and 24th are pretty ordinary with moderate cross-shore winds. The 30th and 31st are also average with fresh breezes and messy conditions.
And from August 1st onwards, the swell jumps big – 10ft to 15ft – but those are too big for this break, and the wind is often strong or onshore, creating lumpy, dangerous conditions. The 4th and 5th settle back to smaller, cleaner waves but nothing special.
All in all, Tuesday the 21st morning and Saturday the 25th morning are your best bets. The 29th is a promising long-range option if you’re keen on something bigger.
Rusty.

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.
