Table - best surf conditions forecast for Bonza Bay over the next 16 days.
Hey, Rusty here. Let’s break down what’s happening at Bonza Bay in feet and miles per hour.
Water temp is 64°F, which is about 4°F colder than normal. Feels like winter.
We’re in a quiet spell right now. The first real surf shows up on Thursday, July 9th. The morning brings a 12ft SSW swell, 12-second period. Combined energy is 5052 – that’s a lot of power. But it’s oversized for here, only for experienced surfers. Winds are cross-offshore from the SW, keeping it clean.
Your best bet is Friday, July 10th. The swell eases to 8ft from the S, period 14 seconds – long, lined-up groundswell. Energy is still strong at 2407. Morning winds are WSW cross-off, so expect clean, well-shaped waves. This is the session to aim for if you’re intermediate or better.
Saturday the 11th is a write-off – light rain and onshore east winds ruining the surface.
From Sunday the 12th through the week, the swell drops and the winds shift, creating choppy conditions. There are still some 7ft waves on Monday the 13th, but with a short 8-second period, it’s not worth it.
The real gem comes on Saturday, July 18th. Glassy morning, no wind, a clean 5ft S swell with a 10-second period. Energy is moderate at 514. That’s as good as it gets for this break – small, clean, and super user-friendly.
Later in the second week, Tuesday the 21st afternoon turns glassy again, but the swell is only 3ft with a very long 17-second period. That’s longboard territory.
Crowds pop up sometimes at Bonza Bay, but nothing too hectic.
Rusty, out.

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.
