Bonza Bay Surf Forecast and Surf Report

Alright, grab your board, let's see what's cookin' for Bonza Bay over the next couple of weeks. I'm lookin' at the charts and, honestly, it’s a bit of a mixed bag. We've got some serious size comin', but you're gonna have to be patient and pick your moments.

The first real chance to get wet doesn't show up until Monday morning, August 24th. It's small, with knee-to-waist high waves around 3ft from the south. The wind is a light cross-onshore, so it'll be a bit bumpy, nothin' special. Energy is low-to-moderate (204). The water temp is sittin' at 66°, which is a touch cooler than normal for this time of year.

Tuesday the 25th sees an upgrade in size and quality. The morning looks pretty good with chest-high 4ft south swell but with a very long 17-second period. That's a proper groundswell, loads of energy (1120), and it's gonna wrap in nicely. The wind is light and cross-shore, which isn't perfect, but it'll be workable. Afternoon gets a little bigger at 5ft from the SSW, but the wind picks up and brings a bit of chop.

Wednesday the 26th is where it gets tricky. The swell jumps up to 6ft in the morning with offshore wind, but it's rainy and the period is still that super long 17 seconds. This kind of long-period energy at a river mouth can make things a bit straight and fast. By the afternoon, it's 8ft and onshore, completely blown out. That's a pass.

We then hit a real dry spell for a few days. Thursday the 27th and Friday the 28th have size, but the wind is howling from the NE at 28 to 31 mph, turning the ocean into a washing machine. Not worth paddling out at all. The same story continues into the weekend of the 29th and 30th – messy, lumpy, and onshore. Heads up, the wind on the 29th drops the swell to a measly 2ft. There's a serious gap of poor conditions from Wednesday afternoon right through to Sunday.

Things finally look interesting again on Monday afternoon, August 31st. The wind swings offshore from the west, and we get a clean 6ft SSW swell. The period is a short, wind-swell 8 seconds, but with light offshore winds and clean conditions, the sets will be fun and punchy. This is one of the better windows in the first week.

Now, for the true standout. Get this circled on your calendar for Thursday, September 3rd. The morning session is looking *perfect*. We have a solid 8ft to 12ft SSW groundswell with a 13-second period. That's massive wave energy (5912)! And the wind is light offshore from the west. This is a clean, powerful, stand-out day. However, at over 8ft, this is strictly for the experts. The river mouth could handle this size, but the paddle out will be a mission. If you're not a seasoned charger, just watch from the beach.

Friday, September 4th and Saturday the 5th are also pumping, with 10ft to 12ft swells and clean offshore winds, but again, the size is too big for all but the gnarliest locals.

The second week is hit-and-miss. We see a pulse of energy on Tuesday, September 8th with a 7ft S swell, an incredibly long 18-second period, and offshore wind. That's another proper groundswell, but at that period and size, it's only for the very experienced on a boat or at a reef.

So, to wrap it up: the real winner for the everyday surfer is Monday afternoon, August 31st, for a clean, post-work session. For the big-wave crew, the morning of Thursday, September 3rd, is the highlight of the whole forecast. Don't be fooled by the big numbers mid-week; the wind will ruin it for most days.
