The Lowdown

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

Straight up, this is a bit of a tough stretch. The first few days are looking pretty average, with a lot of cross-shore wind mushing up the shape. The water is sitting at 64°F, which is a full 5°F colder than usual for this time of year – that’s a notable chill, so don’t forget the booties.

We’ve got a long wait for the good stuff. The first real standout won’t arrive until the morning of Monday, July 20th. The wind will be glassy, dead calm from the east at 3 mph, and we’ll have a 4 ft swell from the southeast with a 12-second period. The combined energy is moderate (689). It’s not huge, but with that glassy surface, it’ll be clean and fun for a cruiser.

The pattern then gets a bit sloppy again until the morning of Tuesday, July 21st. That morning glass-off with a 4 ft south-east swell will be similar quality, but again, nothing massive.

Now, hold onto your board. The morning of Thursday, July 23rd brings a massive 12 ft southwest swell, with a 12-second period and glassy conditions. The combined energy is through the roof at 5536. This is proper, powerful groundswell. But – and this is a big but – that size is way too big for this break. The report says it’s too big for Bonza Bay. This is expert-only territory, and even then, it’s likely to be a washing machine. It’s a spectacle, not a session.

The same goes for the morning of Monday, July 27th. We’re looking at a 16 ft south swell with a 14-second period, energy hitting 8554. That’s a monster. Absolutely for big-wave chargers only, and again, probably too much for this spot.

The best bet for the average surfer comes later. The morning of Wednesday, July 29th is a gem. An 8 ft swell from the east-southeast, with an 11-second period, and the wind is completely glassy. The energy is strong (1600). This is a solid, clean swell that’s right on the limit for experienced surfers. It’s a big day, but it’s the best combination of size and clean conditions we’ll see. The wind is calm, offshore, and the swell direction is from the southeast, which is the optimum for this river mouth. Expect some crowds here, as it’s a break that’s fairly consistent.

After that, the Friday morning of July 31st is another good window. A 8 ft southwest swell, 9-second period, with glassy conditions. The energy is strong (1713). The period is a bit short, so it won’t have the same grunt as the 29th, but it’ll be clean and fun for those who can handle the size.

So, the pick of the fortnight is the morning of Wednesday, July 29th. That’s the one to circle on the calendar. The morning of the 31st is a solid backup. The big swells on the 23rd and 27th are just too much for Bonza Bay.

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.
