The Lowdown
Alright, let’s switch that up to feet and miles per hour for the crew that think that way.
So, it’s all about one spot for the next couple of weeks. Don’t rush out the door just yet.
Bawa is the only break on the menu. It’s a reef and point, very consistent, and it drinks up that SW swell. Water temp is normal for the time of year.
The start is a write-off. Monday the 24th and Tuesday the 25th have 6ft to 6ft SSW groundswell with a ton of energy, but the wind is blowing from the wrong direction, making it a mess. Not worth it.
Wednesday the 26th morning is your first chance. Swell drops to about 5ft and the wind goes glassy. You’ll find some clean ones, but it’s not firing.
The clear best day of the early run is Thursday the 27th morning. We’ve got a 4ft SSW swell, but the period is 19 seconds. That’s proper groundswell, with a ton of energy (1882). Glassy conditions means it’s going to be perfect for the experienced surfer.
Friday the 28th gets a little bigger, up to 7ft, but the onshore wind kills it.
Things go quiet over the weekend with smaller, windblown waves. Then we hit the start of September.
Tuesday the 1st of September morning brings a solid 8ft swell with 3749 energy. That’s a heavy ocean. But the wind is cross-on, making it a tricky, expert-only wave.
Thursday the 3rd of September morning is your next standout. A much cleaner 5ft SSW swell, glassy conditions, and good energy at 1191. This is a proper session.
The last few days fade out. Swell drops below 4ft and the wind gets messy again. There are a couple of glassy morning windows on the 5th, 7th and 8th, but the waves are too small to get excited about.
Best on offer: Thursday the 27th morning for that clean, long-period groundswell. Thursday the 3rd of September morning is a close second for the clean conditions on decent sized swell.

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.
