The Lowdown
G’day, Rusty here, your local surf cobbler lookin’ at the waves over Bawa for the next couple weeks.
Righto, let’s size it up. The opening of the forecast is a bit of a write-off, with Wednesday the 2nd bringing storm risk and a light cross-onshore breeze messing with a 6ft SW swell. The water’s a touch warmer than average for this time of year, sittin’ around 86°F. Not the sorta session to get excited about, but hang in there.
Things get seriously good from Thursday the 3rd morning. We’ve got a clean 5ft SW groundswell and a nice 15-second period, and the wind switches to an offshore NNE breeze at just 3 mph. That’s the kind of glass that gets a surfer’s heart thumping. The lines will be well-shaped, though the long period means the sets might come in slower, making paddling out a bit easier between the bomb sets. This is the standout session of the early run – proper quality for experienced riders.
Friday the 4th is also worth a paddle. That same groundswell backs off a touch to 4ft SSW, but the wind goes totally glassy with a calm morning and afternoon. You’re looking at clean, silky walls all day. Consistent energy too, with the combined swell energy sitting at 689 (moderate) in the morning.
Saturday the 5th and Sunday the 6th get a bit messy with cross-onshore winds picking up, spoiling the party for a couple days. The swell drops to under 3ft and the conditions get choppy. Not your best bet for a good ride.
There’s another clean-up on Tuesday the 8th morning. The wind goes glassy again, and we get a 3ft SSW groundswell but with a super long 19-second period. That’s some serious pulse from deep water, perfect for the reef and point setup at Bawa. The energy score is solid at 1198 (moderate-strong). A real gem for those who know how to work the lineup.
From there, the surf stays pretty solid through to the second week, but the wind starts mixing in cross-onshore and onshore conditions most mornings. Keep an eye on Saturday the 12th – that’s a whole different animal. The wind goes glassy again in the morning with a 5ft SSW swell, and by afternoon we’re looking at a 5ft SW swell packing a very long 19-second period. The combined energy skyrockets to 2436 (very strong). That afternoon the wind is light cross-shore, but that long-period SW groundswell combined with high energy is prime for the point and reef, but will be too straight for a beach break. Still, for the experienced crew at Bawa, this is the session to circle on the calendar for the second week.
Monday the 13th drops to a 6ft SW swell, but with onshore winds. Not the cleanest. Then Thursday the 17th sees the swell drop off to 4ft with some small cross-onshore breezes, but the water’s still warm and there are small windows if you’re desperate.
So, for the smart money: Thursday the 3rd morning and Tuesday the 8th morning are your top picks early on. If you’re going long range, Saturday the 12th afternoon looks promising – that long-period groundswell energy is a standout, but it’s a week and a half out, so keep an eye on the charts. It’s a solid run of southern hemi groundswells.
Stay salty,
Rusty

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