The Lowdown
G’day, I’m Rusty. Let’s talk about what’s on the cards for Bonza Bay. This is a river-mouth spot, and over the next couple of weeks we’ve got some swell rolling through, but the wind’s going to be a real headache most of the time, leaving just a few windows where it’s actually worth getting wet.
Starting from Thursday the 3rd through Monday the 7th, it’s a grim run. We’re looking at cross-onshore and onshore winds, gusting from 6 mph right up to 25 mph, so it’s choppy and messy. Swell is hanging between 3 ft and 10 ft, but with those winds, it’s unsurfable. The water temp is about average for the season, so no drama there.
Tuesday morning the 8th is the one to circle on the calendar. That’s your standout. We’ve got glassy conditions with a slight air from the SE at just 3 mph. Swell is a clean 5 ft from the east with a 9-second period and 677 wave energy. That glassy surface means the river-mouth should be offering up some smooth, rideable lines. It’s the best session on offer by a long shot.
After that, it’s back to the wilderness. Tuesday afternoon turns cross-shore and poor, and from Wednesday the 9th through Monday the 14th, it’s mostly poor with light onshores and cross-shore winds. Swell drops right off – we’re talking 1.0 ft on some days with weak energy (67-210). There’s a pulse of 6 ft from the south on Monday the 14th but with onshore wind, so that’s a scratch.
The second week is a long-range hope but nothing solid. Tuesday the 15th and Wednesday the 16th bring some 6 ft to 7 ft east swell with cross-shore and cross-on winds – still marginal due to tide and wind.
Thursday the 17th is a write-off with strong 28 mph cross-offshore winds and 5 ft to 6 ft swell – that’s kite-surfing weather, not paddle surfing.
The very last note, on Friday the 18th, shows a 7 ft south-west swell with light cross-onshore wind and moderate energy (1757) – but it’s two weeks out, so take it with a pinch of salt.
So, bottom line: Tuesday morning the 8th is your best shot. Everything else in the 16-day window is either blown out or too small. It’s a long wait, but that one morning is a ripper.
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.
