The Lowdown
Alright, Rusty here. Let’s talk about what’s on offer for the next couple of weeks.
The coming days start off a bit average but there’s a build-up happening, and if you play your cards right, you’ll find a couple of real gems. The main break is Bawa, a reef and point. The water’s sitting at 86°, which is bang on average for the time of year, nothing unusual there.
We kick off on Wednesday the 15th. The swell is a solid 5ft from the SSW, with a long 15-second period pushing in some serious energy. The wind is a bit cross-on though, so it’s looking a little messy – not terrible, but you’ll be battling a bit of bump. Thursday the 16th morning is a different story. The same 5ft SSW swell is still there, but the wind goes glassy, and the energy is still high. That’s a clean, crisp morning session. The afternoon gets a bit cross-on again, so aim for the early.
Friday the 17th morning is another glassy one, with a 5ft SW swell at 16 seconds. There’s a risk of thunderstorms, but if you’re out before they hit, it’ll be smooth. The weekend holds up too. Saturday the 18th has clean, cross-off winds all day, with 4ft of SW swell. Sunday the 19th morning is glassy as well, with 4ft SSW swell. Not massive, but clean and fun.
Now, here’s a standout. Monday the 20th morning. The swell jumps to 6ft from the SSW, with a very long 17-second period, and the energy is pumping. The wind is dead calm, glassy. This is excellent surf for experienced surfers. The period is long, so at a point break like Bawa, it’ll reel off beautifully. That’s the best on offer in the first week.
The rest of the week into the 22nd and 23rd gets a bit smaller and more wind-affected, with the swell dropping to 4ft and then 3ft, and the wind turning onshore or cross-shore. Not great, but there’s a chance for a quick one.
Looking into the second week, there’s another real standout. On Monday the 28th morning, we get a 4ft SW swell with a 17-second period and glassy conditions. The energy is building again. Then Tuesday the 29th morning is a solid 5ft SW swell with a 15-second period, glassy, and the energy is strong. Then Wednesday the 30th morning has a 3ft SSW swell with a very long 19-second period, and the energy is huge, with glassy wind. This is a promising stretch, but it’s a week and a half out, so keep an eye on it.
The very end of the run, Thursday the 30th afternoon, sees a 5ft SW swell with 17 seconds and a huge energy reading, but the wind goes onshore, so it’s a bit of a tease.
Overall, the best windows are Monday the 20th morning, and then the morning sessions from the 28th to the 30th. The wave energy is consistently moderate to strong throughout, with those standouts being very powerful. Crowds are sometimes an issue at Bawa, so get out early on the glassy days.
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.
