The Lowdown
Alright, I’m looking at the next 16 days for Bonza Bay, and it’s a bit of a mixed bag. The water temp is sitting at 67°, which is about 1° cooler than the usual for this time of year – nothing wild, just a touch on the fresh side.
The first real chance to get wet comes Saturday the 25th of July, but honestly, it’s not looking great. We’ve got a 4ft SSW swell with a 14-second period, which is a nice long groundswell, but the wind is a light cross-onshore from the SSE. The wave energy is moderate at 842, but the score is low. It’s rideable, but don’t expect anything special.
Sunday the 26th starts with a cleaner cross-shore wind from the ENE, and a slightly bigger 5ft SSW swell. The period drops to 12 seconds, still decent. The energy is a bit lower at 654, but conditions are okay. The afternoon goes downhill fast with a 25 km/h NE cross-shore, chopping up the 3ft swell. Monday the 27th is a write-off – strong SW winds at 35 km/h on the morning, and a short, messy 5ft swell with a 7-second period in the afternoon. Not worth paddling out.
Tuesday the 28th brings a new SSE swell, 8ft on the morning, but it’s short-period at 8 seconds and the wind is howling onshore from the SE. The energy is strong at 1229, but the quality is poor. This one’s more for the kite crew than surfers.
The first real standout shows up on Thursday the 30th of July. The morning session is looking good. We’ve got a 5ft E swell with a 9-second period, and the wind is a light cross-offshore from the NNE. It’s clean, and the energy is moderate at 586. The conditions are described as “very good” – this is your best bet in the first week. Afternoon gets a bit lumpy, but the morning is the window.
The second week gets a bit rugged. Friday the 31st and Saturday the 1st of August have decent swell size (5ft to 6ft) but the wind is a fresh to strong cross-shore from the NE, making it messy. Sunday the 2nd of August has a solid 8ft to 8ft E swell, but with 40 km/h winds, it’s blown out – expert only, and even then, it’s a battle.
Now, things start to get interesting around Tuesday the 4th of August. We’ve got a 7ft ESE swell with a very long 13-second period, and the wind is a light cross-shore from the ENE. The energy is strong at 1595. This is a powerful groundswell, and it’s going to be offering some proper shaped waves, but with that long period, it might break a bit straight at the beach. Keep an eye on the river mouth.
Wednesday the 5th of August fades a bit, but Thursday the 6th holds onto 6ft E swell with light winds. The real cherry on top is Friday the 7th of August. The morning is glassy – SW wind at 5 km/h, with a small 4ft E swell. The energy is weak at 388, but it will be clean as a whistle. Perfect for a longboard or a fun fish.
Saturday the 8th of August morning is also glassy, with a 5ft SW swell. The afternoon builds to 7ft with a 9-second period and light cross-shore wind. It’s a solid option.
If I’m picking the best on offer, I’d say the Thursday the 30th of July morning is the standout for the first week. For the second week, the Tuesday the 4th of August morning has the most power and potential, but the glassy Friday the 7th of August is a close second for pure, clean fun.

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.
