The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for the Bonza Bay area. It's a bit of a mixed bag, and honestly, you're going to have to be patient for the good stuff.
We're looking at a solid stretch of days where the wind is just a pain. Most of the time it's blowing cross or cross-on, making for lumpy, choppy, or generally poor conditions. The wave energy is mostly moderate, with values in the hundreds, but the quality just isn't there for a clean paddle out.
The water temp at Bonza Bay is sitting at 67°, which is about 1° cooler than normal for this time of year. Nothing crazy, just a touch on the cool side, so you might want that spring suit.
Now, let's break it down. We kick off on Wednesday the 12th of August with a 5ft east swell, but it's a complete write-off with a fresh cross-on wind from the ENE. Thursday and Friday are more of the same – messy, cross-shore winds and small, poor surf. There's a brief window of hope on Saturday morning the 15th. The conditions turn glassy with a light SSE breeze, and we have a 4ft swell from the east with a short period of 8 seconds. The energy is weak though, at 243. It's surfable, but nothing to write home about.
Then we hit a long, dead zone. From Saturday afternoon all the way through to the middle of the following week, it's a constant battle of cross-shore winds and poor surf. The swell hangs around, but the wind keeps ruining it. There's a bit of a pick-up on Wednesday the 19th with a 7ft SSW swell, but it's still a cross-shore mess and only considered marginal.
Things get a bit more interesting heading into the weekend. On Friday, the 21st of August, we get a glimmer of hope. The afternoon turns glassy with a light ENE breeze, and a 6ft SSE swell rolls in with a period of 8 seconds. The energy is moderate at 599, and the forecast suggests very good conditions. This is probably the standout of the whole period, but it's over a week away, so temper your expectations.
The following Sunday morning, the 23rd, also looks promising. We have a clean offshore wind from the SSE and a 6ft swell from the SSW with a longer period of 13 seconds. The energy is strong at 1239, which means there's some real power behind it. However, it's marked as marginal, so tides could be a factor. That longer period groundswell will be best on a point or reef, but Bonza Bay is a river mouth, so it might break a bit too straight. Still, for the more experienced crew, it's worth a look.
So, to sum it up: the best bets are the glassy windows on Friday the 21st afternoon and the offshore morning on Sunday the 23rd. The rest of the time, you're better off checking the wind forecast before you bother paddling out.
Rusty, signing off.

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.
