The Lowdown
Alright folks, Rusty here. Let’s see what this stretch of the coast has in store for us. We’ve got a single spot on the radar, Bawa, and it’s looking like a solid run of swell is lining up, with some real standouts in the mix if you time it right.
The long-range picture is promising. A persistent, long-period SSW groundswell is the main event here, rolling in for over a week straight. The combined energy is moderate to strong, hitting values like 1145 and 1531, so there’s plenty of juice in the water. The water temp is about average for this time of year, nothing weird going on there.
The first real action kicks off on Wednesday, July 15th. The morning is the pick of the whole run in my opinion. We’re looking at a clean 6ft SSW swell with a 16-second period – that’s proper groundswell energy. The wind is dead calm, glassy as a mirror. This is excellent surf for experienced surfers, the kind of morning you set your alarm for. The swell is a bit overhead, so it’s not for the grommets, but for anyone who can handle it, it’s going to be pumping. The energy is cooking at 1505.
Thursday morning, the 16th, is also a beauty. Still a 5ft SSW swell, still glassy with a slight NE breeze. The wave comment says “expect very good surf conditions,” and I’d agree. It’s a touch smaller than Wednesday, but the quality will be there. This is a consistent spot, so it’s likely to have a few crew out, but on a morning like this, it’s worth sharing.
The weekend has a few windows, but the wind gets a bit tricky. Friday and Saturday mornings both have that glassy feel, but there’s a risk of thunderstorms lurking. The swell drops a bit to 4-5ft, but it’s still clean. If you can dodge the rain, it’ll be fun.
Now, look ahead to Monday, July 20th. The morning session is another standout. The swell jumps back up to 6ft from the SSW, with a 17-second period. The energy is cranking at 1809. The wind is a light cross-offshore from the NNE, which will keep the faces clean and lined up. Again, this is one for the experienced crew, but it’s a top-tier forecast.
The following week gets a bit mixed. Tuesday the 21st has a glassy morning with 5ft swell, but the energy drops. By Wednesday and Thursday the swell fades into the 3ft range, and the consistency gets patchy. There’s a fun little window on Monday, July 28th with a glassy morning and a 3ft swell, but the period is a very long 19 seconds, which can make Bawa a bit walled out and tricky to find a proper pocket. It’s worth a look if you’re keen, but it’s not the standout.
The best of the whole run is hands-down Wednesday, July 15th and Monday, July 20th mornings. Get on it.
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.
