The Lowdown
G’day, Rusty here. Let’s break down what’s coming for Bonza Bay over the next sixteen days.
The first few days are a bit of a write-off. From Thursday the 30th through the weekend, we’ve got swell around 5ft to 8ft from the ESE, but the wind is messy and cross-shore, churning up a lumpy chop. Wave energy is moderate, but the conditions are poor. There’s a gap of several days with no real quality surf.
Now, Monday the 3rd of August is the real standout. The wind goes glassy, and the swell sits at a clean 6ft from the ESE. The combined energy is moderate (809 to 669), but that glassy surface means smooth, lined-up waves. The water temp is around 69°, which is about normal for the time of year. This is a river mouth break, fairly consistent, and with a southerly swell direction, it’ll hold shape. Crowds can show up sometimes, but for a morning session like this, it’s prime.
After that, the rest of the week is small and choppy. Swell drops to 3ft to 5ft, with cross-breezes. There’s a little spike on Thursday the 6th with a 4ft SSW groundswell at 15 seconds, but it’s a cross-off breeze and only moderate energy.
The second week turns wild. Sunday the 9th sees a 8ft S swell with a cross-onshore breeze, sloppy. Monday the 10th blows up with a 15ft to 13ft ESE swell, but the wind is a near gale at 34 mph, so that’s for experts only or kite territory. The energy is massive (5471 to 5835), but poor surf quality. Tuesday the 11th cleans up with a 8ft SE swell dropping to 6ft, light cross-off winds, and clean conditions. That’s a decent option for the afternoon, but not as good as the glassy Monday the 3rd.
The final days fade out with small, weak swells and cross-breezes. The best call is Monday the 3rd of August. Get out there early.
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.
