Table - best surf conditions forecast for Bunbury Bay over the next 16 days.
Alright, let’s get into it. Bunbury Bay is the only game in town for this entire stretch, and it’s a mixed bag over the next couple of weeks. The water temp is sitting at 63°F and feels a bit colder than normal for this time of year, so you’ll want a decent wetsuit.
We’ve got a bit of a wait before the real fun starts. Saturday the 11th offers up a 5ft WSW swell with a light cross-off breeze, and the swell energy is moderate at 674. It’s clean, but not going to blow you away. Still, it’s a start.
Sunday the 12th morning is where things get interesting. You’ve got a 5ft WSW groundswell rolling in with a long 15-second period, and the wind is glassy – dead calm from the NNW. That’s about as good as it gets for clean conditions. Swell energy is strong at 1294. This is a standout morning, especially for a beginner-friendly spot like Bunbury Bay. The afternoon turns a bit crummy with a cross-on breeze though.
Monday the 13th morning is the best of the whole outlook. 6ft of WSW groundswell, a very long 16-second period, and glassy conditions from the ESE. This is for experienced surfers only at that size, but the energy is very strong at 1863 and the waves will have proper power and shape. If you’ve got the skills, get in the water. The afternoon gets messy with a cross-on wind.
Tuesday the 14th still has some clean 5ft to 5ft W swell in the morning with a cross-off breeze, but nothing touches Monday. Good, not great.
Then we hit a rough patch. From Wednesday the 15th through to Saturday the 18th, it’s all poor surf. Strong onshore winds, lumpy chop, and on the 18th the swell pumps to 12ft (7998 energy) with a fresh cross-onshore. That’s just too big and messy for this break – more of a kite-surfing setup than a paddle session.
Sunday the 19th brings relief. Morning has 7ft W swell with zero wind – glassy – and excellent conditions for experienced surfers again. Afternoon stays clean with a 6ft WSW swell and glassy wind. A solid end to the weekend.
After that, the swell drops off. The 20th through the 22nd is marginal, with small 4ft to 5ft swells and mixed winds. The 23rd pushes back up to 8ft WSW with a long 17-second period, but light cross-onshore wind keeps it from being pristine. Still, that’s a lot of energy (2981) and could offer some fun if the wind plays ball.
From the 24th onward, it’s back to poor surf with onshore winds and choppy conditions through the 25th. But don’t write it off – Sunday the 26th finishes strong with a clean 4ft WSW swell and glassy conditions in the afternoon (1158 energy). A nice note to end on.
So, if you’re picking your moment: Monday the 13th morning is the absolute stand-out, and Sunday the 19th is a very close second. Don’t sleep on those glassy windows.

Information about the Bunbury Bay Surf forecast
The above surf forecast table for Bunbury Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bunbury Bay can be found by selecting the local surf guide option on the grey menu. Our Bunbury 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 (Bunbury 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 Bunbury 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.
