The Lowdown

Alright, let’s break down what’s cookin’ at Bonza Bay.

The first week’s a bit of a struggle, starting Sunday the 2nd through Wednesday the 6th. Wind’s mostly cross or cross-shore, and the reports keep saying “marginal.” You got chest-to-head-high swell from the ESE, mostly 4 to 8 feet, but the wind’s putting a nasty cross-chop on it. The combined energy is moderate to strong, hitting 1666 Sunday morning, but the quality’s just not there for a clean ride. Patience is the move.

Come Thursday the 6th, we get a change. Bonza Bay is a river mouth, and it wakes up when the swell swings south-southwest. Thursday morning shows a 3-foot, 15-second SSW groundswell with a light 6 mph WSW wind that’s cross-offshore. The water's about 69°, which is normal for this time of year. The combined energy is 519, moderate, but the clean conditions are the real win. The report says “expect very good surf conditions.” It’s a bit small, but if you’ve got a log or a funboard, that Thursday morning glass-off is a nice little window.

Friday the 7th through Saturday the 8th is messy. Friday has a fresh 22 mph crosswind, and Saturday gets a strong 25 mph breeze with a junk 7-second swell. Not worth suiting up. But hold on—Sunday the 9th is a different story. We’re looking at a solid 8-foot SSW swell with a very long 16-second period. Combined energy is a massive 4760, and the wind is a clean offshore from the west-southwest at 12 mph. That’s proper groundswell hitting a river mouth. The crowd is “sometimes,” so you might see a few others, but this is the standout session of the whole two weeks. Just be warned: 8-foot is expert-only territory at a spot like this.

Monday the 10th gets even bigger—a 12-foot south swell at 14 seconds, with energy at 4493. The wind is light and offshore in the morning, but the forecast is blunt: “the swell is predicted to be too big for this break.” That’s a washout or a close-out wave for most. Leave it to the locals who know every bend of the channel.

From Tuesday the 11th, it’s all downhill. Swell drops from 8 feet to below 2 feet by the 14th and 15th. Wind stays cross or onshore, and the energy fades into the low hundreds. The last week, from around the 13th to the 17th, is a long stretch of small, weak, or choppy days. By the 15th, you’re looking at flat, bumpy nothing.

So here’s the word: Best bet for a clean, fun session is Thursday the 6th morning. But the real highlight, the one you want to plan around, is Sunday the 9th—8-foot, long-period SSW groundswell with offshore wind. That’s the day for experienced surfers to get some proper waves at Bonza Bay.

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.
