The Lowdown
Alright, Rusty here, checkin’ the bones for Bonza Bay.
First off, the start is a bit flat. Saturday the 29th and Sunday the 30th ain’t great. But Saturday morning has a little window – clean 3ft swell from the SSE, 12-second period, and light cross-offshore wind. Combined energy is moderate (235). Water temp is about 67°, which is normal for now. That’s the best early session.
Sunday’s a mess. Monday the 31st morning is a real gem. Glassy, 3ft from the east, 10-second period, and energy at 233. It’s small but clean. That’s the pick of the first week.
Into the second week, Wednesday the 3rd of September morning has a solid 7ft swell from the SSE, but it’s short-period (7 seconds) so a bit lumpy. Wind is clean, energy is moderate (501). That’s one for the more experienced guys. The afternoon gets blown out.
Thursday the 4th and Friday the 5th have size but the wind is trash. The energy hits 1155 on Friday afternoon, but it’s cross-onshore and choppy.
The big one is Thursday the 10th of September. The models are showing a massive 13ft east swell, 10 to 11-second period, and energy through the roof (3480 and 3911). Wind is good, but 13ft is way too big for this break. That’s only for experts, and it’s a risky one. For the rest of us, it’s a show.
So, the best waves are Monday the 31st morning for clean small stuff, and maybe Wednesday the 3rd morning for a bigger, punchier session. The 10th is a monster, but not for paddling.
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.
