Table - best surf conditions forecast for Bonza Bay over the next 16 days.
Hey, Rusty here. Let’s talk Bonza Bay over the next couple of weeks. It’s gonna be a ride.
We’ve got some surf straight away. The water is 64°, which is way colder than normal for this time of year – more than 5° down, so that’s real unusual. You’ll need a thick wetsuit.
The first standout is this Saturday morning, July 11th. Glassy conditions with light rain and a clean 7ft southerly swell with a 13-second period. The combined energy is strong at 1425, so there’s real power. That’s gonna make for excellent, punchy waves, but it’s for experienced surfers only – beginners stay out. Saturday afternoon holds a 7ft S swell at 12 seconds, still glassy. Sunday morning, July 12th, stays clean with a 5ft S swell at 12 seconds and glassy conditions – very good.
Sunday afternoon turns ugly with an east wind at 12 mph, cross-onshore, killing the quality. Monday and Tuesday are messy with cross winds and shorter period east swell. Not worth it.
The next real gem is Thursday morning, July 16th. Calm, glassy conditions with a clean 3ft SSW groundswell, 15-second period. That’s a super long period swell, so the waves will have heaps of shape and energy, but at Bonza Bay – a river break – it might run a bit straight. Still, with no wind, it’ll be clean and fun for the experienced.
But the biggest standout is Friday, July 17th. We’re talkin’ a 10ft SSW swell with a 14-second period, and the wind is cross-offshore at 20-25 mph. The combined energy is huge – 3600 – but the forecast says the swell is just too big for this break. That’s expert-only, and even then it’s iffy. Saturday morning, July 18th, drops to 8ft S swell, 13 seconds, with clean cross-offshore wind. That’s a better call for strong surfers.
After that, it’s pretty dry. Onshore junk and weak swell from the 19th to the 22nd, with energy dropping to 42. There’s a quick window on Thursday morning, July 23rd, with a glassy 3ft S swell at 14 seconds, but it’s short.
The last chance is Sunday, July 26th. A 7ft SSW swell with a huge 17-second period, combined energy of 2633, but the wind is light cross-onshore. Then Sunday afternoon it jumps to 8ft with a 19-second period and energy over 5000 – that’s massive groundswell. Powerful and long, but that super-long period could make it tricky at the river mouth. For the brave.
So, the best of the bunch is Saturday morning, July 11th – glassy, solid 7ft S swell, excellent conditions. If you miss that, Thursday morning, July 16th, is the next clean option. The end of the run on July 26th has potential, but it’s a long way off.
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.

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.
