The Lowdown
Alright, Rusty here, let’s talk about what’s on offer at Bonza Bay.
Right off the bat, we’re looking at a pretty quiet start. The first few days are a bit of a write-off with marginal conditions and messy winds. The real window of interest doesn’t open up until the end of the first week, so don’t get your hopes up for the immediate days ahead.
Saturday 25th July is a bit of a tease. We’ve got a 4ft SSW swell rolling in with a 14-second period, giving it some decent energy (1043). That long period means the sets will be clean and lined up, but the wind is a light cross-shore, so it’s not going to be perfect. It’s a marginal call, and the water is a bit colder than usual at 65°. The crowd factor is there too – can get busy here.
Sunday 26th July sees a similar size swell, but the wind cranks up to 16 mph from the ENE, turning it into a lumpy cross-chop. Not great.
Monday 27th July is a total no-go with fresh cross-shore winds and a drop in swell size. The whole week stays pretty average until Saturday 1st August. That afternoon things suddenly look interesting: an 8ft swell from the E, short period (8 seconds), but the wind goes glassy. That’s a magic moment – clean, smooth conditions, and the energy is strong (866). This is your standout window. The swell is a bit chunky for beginners, but for the experienced crew, it’s going to be clean and punchy.
Sunday 2nd August keeps the size up around 7ft to 8ft, with a longer period (11 seconds) and moderate cross-shore winds. The energy is high (1089-1361), but the wind keeps it from being perfect. Still, it’s a solid option.
Monday 3rd August eases off a touch, but we’ve got a 7ft ESE swell with a 12-second period and light cross-shore wind. The energy is still strong (1209), and the cleaner conditions make it a good call for the morning.
After that, the swell steadily drops through the week, with smaller waves and increasing wind. By the 9th of August, it’s down to 3ft and clean, but the energy is weak (209). A nice little morning session for the log if you’re keen.
So, to sum it up: the standout is Saturday 1st August afternoon – glassy, solid 8ft E swell, perfect for a late session. Sunday 2nd and Monday 3rd are also worth a look, but the wind will be a bit more of a factor. Everything else is either too small, too windy, or too messy. Patience is the game here.
Rusty.

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.

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.
