The Lowdown
Alright, let’s break down Bonza Bay. This is a river break, fairly consistent, exposed to the south. Right now the surf’s flat or junk. Monday through Wednesday are a write-off with onshore winds and weak swell.
Thursday 30 July morning starts to wake up. Clean 2ft ESE swell from an offshore WSW breeze at 3 mph—combined energy (980) is moderate. Not huge but it’s clean and rideable for intermediates.
Friday 31 July morning is the pick. Glassy conditions, south wind at 3 mph, 5ft ESE swell at 9 seconds, combined energy (560) is moderate. That’s clean, glassy, and a really nice size for this setup. Friday afternoon gets lighter but onshore.
Saturday 1 August is 6ft E swell in the morning, but cross wind and short 8-second period means it’ll be lumpy.
Sunday 2 August brings a very long 21-second SSW groundswell—only 2ft but that period makes it tricky for a river mouth. Combined energy (612) is moderate.
Monday 3 August afternoon goes glassy with a 3ft 15-second SSW swell. Clean but small.
Wednesday 5 August is glassy again, but only 3ft—better for a longboard.
The big news is Saturday 8 August: glassy, 7ft S swell, 8-second period, ENE wind at 3 mph. That’s clean and decent size. Good for intermediates.
Sunday 9 August has similar size but cross wind.
Monday 10 August is not for the faint of heart. 10ft E swell, 9-second period, cross SW wind at 12–18 mph. The forecast says this is too big for the break. Only experts should even consider it.
So if you want the best, it’s Friday 31 July morning—glassy and clean with a solid 5ft from the ESE. That’s your call to the water. Saturday 8 August morning is also a strong backup if you’re patient.

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.
