The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking for Bawa.
This is a reef and point that sees a lot of swell and stays consistent, but the next few days are a real struggle. The water temp is about 86°, which is normal for this time of year. From Monday (August 10th) right through to Thursday morning (13th), it’s just risk of thunderstorms and cross-onshore winds messing up what swell there is. The waves are around 6ft to 7ft from the S/SSW, but it’s all choppy and marginal. Not worth the effort.
Things clean up Friday afternoon the 14th. The wind goes dead calm, glassy from the NW at just 3 mph. The swell is a solid 6ft from the south with a 16-second period, giving you long, clean lines. The combined energy is moderate, but the glassy surface is the key here. Saturday morning the 15th is also a good look, glassy again with a 5ft south swell.
The first real standout is Wednesday morning the 19th of August. The wind is glassy from the east at just 3 mph. The swell is a solid 8ft from the SSW with a long 18-second period. The combined energy is strong. This is for experienced surfers only. The reef and point will handle that long-period groundswell beautifully, giving you well-shaped, powerful sets from the optimum SW direction. The crowds can pop up sometimes, but this is a serious session.
Thursday morning the 20th is similar, maybe a touch bigger at 8ft. Then Friday morning the 21st is another standout: the swell hits 8ft from the SSW again, period at 18 seconds, with glassy wind from the SE. The combined energy is very strong, making this exceptional but strictly for experts. The direction is right on the money.
The surf backs off after that, but there’s a final clean session on Tuesday afternoon the 25th with a glassy wind and a 6ft SSW swell to round things out.
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.
