The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Bonza Bay over the next couple of weeks.

Alright, so the outlook is a bit of a mixed bag. We’ve got some decent swell pulsing through, but the wind is going to be the main story, and it’s not always a friendly one. There’s a lot of strong cross-shore and cross-onshore wind in the forecast, which will chop things up. The water is a bit colder than usual for this time of year, sitting at 66°, so you’ll want a decent wetsuit.

We start off on Friday, 21st of August afternoon with some small waves. A 4ft SSW swell is rolling in with a 12-second period, and the combined energy is moderate at 506. The wind is a light ESE breeze, so it’s not terrible, but it’s not brilliant either. It’s a bit marginal, but you could get a few if you’re keen.

Saturday, 22nd of August, is a write-off. The morning is a cross-shore 19 mph SW wind with a tiny 2ft S swell, and the afternoon gets nasty with a 31 mph near-gale cross-shore wind and a 8ft lumpy, short-period swell. Stay out of the water.

Sunday, 23rd of August morning has a big 8ft SW swell with a 10-second period, and the combined energy is strong at 1841. But the wind is a cross-shore SW breeze at 16 mph, creating a cross-chop. It’s only for the experienced crew, and even then, it will be messy. The afternoon drops to 5ft but the wind goes cross-onshore, so it’s no good.

Monday, 24th of August is small and weak with a 3ft S swell, and the wind is light cross-onshore. Nothing to get excited about.

Tuesday, 25th of August morning sees a nice 5ft SSW swell with a very long 15-second period, and the combined energy is strong at 1085. The wind is a light S cross-onshore breeze. This is a highlight. The long period is great for a setup like this, giving proper lines and good energy. The afternoon is similar but a touch smaller.

Wednesday, 26th of August morning is a tricky one. A 6ft S swell with a 16-second period (very long) and combined energy of 1796 (strong). But the wind is a cross-onshore E breeze at 9 mph, which will mess with the surface. The afternoon sees the swell jump to 8ft, but the wind cranks up to 19 mph cross-onshore, so it’s a lumpy, blown-out mess.

Thursday, 27th of August, we get a 5ft S swell with a 16-second period, but the wind is a fresh 22 mph cross-shore. It’s going to be lumpy and hard work.

Friday, 28th of August morning is a bit more promising. A 5ft S swell, 13-second period, with a gentle cross-shore SSW wind. It’s marginal but the cleanest it’s been in a while. The afternoon brings a 6ft E swell with a 10-second period and a light onshore breeze, so it’s small and wind-affected.

The best surf of the whole period looks like it will be on the morning of Wednesday, 2nd of September. We’ve got a 6ft E swell with a 9-second period, and the wind is a gentle cross-offshore from the north. It’s clean, and the combined energy is moderate at 696. This is the one to circle on the calendar. It’s a bit far out, so keep an eye on the forecasts, but this is the standout window.

The rest of the second week is a mix of small, windy, or messy conditions. Thursday, 3rd of September and Friday, 4th of September are not worth your time. Saturday, 5th of September morning has a 8ft E swell, but the wind is a moderate cross-shore, so it’s a bit of a chop.

So, to sum it up: the first week is a struggle with wind. The standout is the Wednesday, 2nd of September morning for clean, chest-high waves. Otherwise, it’s a case of picking the least windy windows.

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.
