The Lowdown
Alright folks, Rusty here. Let's have a look at what Bonza Bay has on offer over the next couple of weeks.
We’ve got a bit of a slow start coming up. The surf isn't really going to get going until later in the month. The first solid chance doesn't show up until Monday the 31st of August. Before that, there’s a fair bit of chop and cross-shore wind that’s gonna make things pretty ugly.
The standout session of the whole run looks to be Monday morning, the 31st of August. The wind will be light and cross-offshore, giving us clean waves. The swell is around 5 ft from the SSW with a period of 11 seconds, which is a nice bit of groundswell. The energy is moderate (749). The water temp is sitting around 66°F, which is just a touch cooler than average for this time of year. It won't be huge, but it’ll be your best shot at a proper session. Keep in mind, crowds are *sometimes* an issue at this spot, so an early paddle might be the go.
Now, let’s look ahead. For the first week of September, the surf stays on the smaller side with a lot of cross-shore breeze. Then, we get a bit of a warning for Friday the 4th of September. The swell is predicted to pump with a 13 ft southerly swell in the morning and 10 ft in the afternoon. That’s a heap of water, and honestly, it's likely going to be too big and unruly for this spot. The energy is very strong (2778). That’s expert territory only. The wind is a fresh cross-shore, so it’ll be lumpy on top of that. The smaller, more manageable stuff comes the next morning on Saturday the 5th of September, with a 7 ft SSE swell but again, there’s a moderate cross-shore chop.
After that, things get a bit small and messy again. We get a short window on Tuesday the 8th of September with tiny clean waves. The Tuesday morning has a 2 ft swell from the S with a glassy cross-offshore wind, and the Tuesday afternoon goes glassy with a 4 ft swell from the E. It’s tiny, but if you’re desperate, that afternoon looks clean for a longboard.
So, bottom line: the 31st of August morning is your best bet by a long shot. The 5th of September morning is worth watching if the 4th cleans up, but it’s a gamble.
Stay stoked,
Rusty

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.
