The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way over the next couple of weeks.
Right off the bat, it’s a bit of a slow start. The first solid surfing window doesn’t really open up until Sunday the 13th. Before that, we’ve got a whole lot of messy, blown-out, or just tiny conditions. We’re talking about a solid week of waiting for the ocean to get its act together.
The standout session is hands down Sunday afternoon, the 13th, at Bonza Bay. The wind is set to go light and offshore out of the NW, which is exactly what we want. That’ll clean things right up. We’re looking at a solid 7ft swell from the east, with a moderate 9-second period. The combined energy is strong, sitting at 1115, so there’s plenty of push. This one is for the experienced crew though – that’s a fair bit of size. The water is around 66°, which is about average for this time of year, so no surprises there.
The other real highlight to keep an eye on is the morning of Saturday the 19th. It’s a bit further out, so less certain, but it’s got potential. The wind is looking gentle and offshore from the NNW, and we’ve got a chunky 8ft swell from the east. The period is a short 7 seconds, so it’ll be a bit crumbly, but it’s going to be big and clean. The energy is strong again (1025), and the offshore breeze will be the key. This is another expert-only window with that size.
For the rest of the period, it’s a mixed bag. Monday the 14th morning has a glassy, clean vibe with 4ft swell, but it’s a smaller window. The 16th afternoon has a solid 8ft swell from the SW with a cross-offshore wind, but the period is short (8 seconds), so it’s a bit of a close-out machine. The 20th has some size, but the wind is fresh and messy.
If you’re looking for the absolute best, set your alarm for the afternoon of the 13th. That’s the one. The 19th morning is the long-range wildcard.
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.
