The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s brewing for the next couple of weeks. We’ve got one main spot on the radar, and it’s offering up some proper action if you time it right.
Right off the bat, Bawa (reef and point) is looking like our main player. It’s a very consistent setup, exposed to the SW swell, and it likes it best from that direction. The water temp is sitting at a warm 86°, which is about 2° warmer than normal for August, so nothing too crazy, just a nice little warm pocket.
The first few days of the week are a bit of a write-off. Monday’s a mess with cross-onshore wind and choppy conditions, and the swell is a mixed bag. Tuesday sees a spike in energy, with the combined energy hitting 2590 (moderate to strong) and a 8 ft W swell, but the wind is cross-off, keeping it clean but a bit tricky. That 8 ft is pushing it for beginners, so this one’s for the crew with some experience.
Now, Wednesday morning the 5th of August – that’s where we start to see the light. Offshore wind from the NNW at 16 mph, clean lines, and a solid 5 ft SSW groundswell with a 15-second period. That’s a long period, and at a reef and point like Bawa, that’s gold. The waves will have real punch and shape, and the sets will be spaced out, making paddling out a bit easier. The energy is strong at 1965. This is a standout session for experienced surfers.
The weekend brings a real treat. Sunday the 9th of August, we’ve got glassy conditions in the morning. Wind is from the NE at just 3 mph, flat calm, and the swell is a clean 6 ft from the SSW at 15 seconds. The energy is still strong at 1836. This is the pick of the bunch – clean, lined up, and offshore. Magic. Expect some crowd action though, as it’s sometimes busy, and that’s for good reason.
After Sunday, things start to break down again. The wind swings onshore from the south, and while there’s plenty of swell through the second week, the quality takes a hit. The period stays solidly long (15-18 seconds), which keeps the potential, but the onshore and cross-onshore winds will chop things up. The 11th of August sees a big 8 ft SSW with a 19-second period, but with the wind howling onshore, it’s a no-go for a paddle. Might be worth a look for the kite crew, but for a surf, leave it.
From the 12th onwards, it’s a lot of marginal conditions with light cross-onshore winds and smaller energy levels dropping below 2000. The 18th of August, the final Tuesday afternoon, does show a glimmer: glassy conditions again, a solid 7 ft swell at 17 seconds, and energy at 3023. It’s a long way out, so keep an eye on it, but the potential is there for another cracker.
Overall, the two standout windows are Wednesday morning the 5th of August for the offshore and power, and the absolute gem: Sunday the 9th of August for the glassy, clean perfection. Don't sleep on that one.

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.
