The Lowdown
Hey, it’s Rusty. Let’s talk about Bonza Bay in feet and miles per hour.
Right off the bat, the water’s running at 65°F, which is about 4°F colder than normal – that’ll get your attention on the paddle out.
We’ve got surf starting Tuesday morning the 14th. A clean 6ft swell from the ESE, period around 9 seconds, and zero wind – dead glassy. The combined energy is moderate at 544, so there’s some fun grunt. Tuesday’s the real standout early on. Tuesday afternoon stays glassy with a 6ft easterly swell and energy at 611. That’s your best bet.
Wednesday the 15th: 5ft easterly swell in the morning with a cross-off wind at 9 mph, still clean. Afternoon gets cross-shore wind and bumpy conditions – skip it.
Thursday the 16th morning is another beauty – glassy again, 4ft easterly swell with an 11-second groundswell period, energy up at 695. Afternoon turns light cross-onshore and marginal.
Friday the 17th: small 3-3ft SSW swell, cross-winds at 12 mph, not great.
Saturday the 18th: size jumps to 7ft from the south, but the wind is 16-19 mph out of the ENE, creating lumpy cross-chop. Energy is strong (1288-1435) but it’s messy – better for kiting.
Sunday the 19th: 5-5ft south swell, still cross-winds at 12 mph, nothing clean.
Monday the 20th morning: a huge 10ft SW groundswell with insane energy at 3952. But it’s too big for this break – glassy but only for experts. Avoid.
From the 21st onward, it’s patchy. The 22nd morning has 5ft SSW swell with a 14-second period and light cross-wind, clean but only marginal quality. The 23rd has similar size and period but moderate cross-winds. The 25th and 26th bring 6-7ft SSW and S swells with strong energy (1981-2043) but fresh cross-winds at 19-22 mph make it lumpy.
From the 24th through the 29th, there’s a long stretch of poor to marginal conditions – the swell drops to 3-3ft, and winds are often over 12 mph or even strong at 25 mph. The 28th and 29th have small groundswell with 15-16 second periods, but light cross-winds and chop keep it from being any good.
Bottom line: Tuesday the 14th and Thursday the 16th morning are your standout windows. Clean, glassy, fun-sized swell. The rest is wind-affected, too big, or too small. Bonza Bay stays fairly consistent, so don’t lose hope, but pick your moments.
Rusty out.

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.
