The Lowdown

Alright, Rusty here. Let’s talk about the surf on offer at Bawa.

We’ve got a full plate of swell through the whole window, but the start of the week is a mixed bag. From Sunday the 30th through Tuesday the 1st of September, the conditions are a bit on the scratchy side with cross-onshore and onshore winds messing with the surface, so those days are more for the die-hards who don’t mind a bit of chop. The swell is building, hitting around 8ft by Tuesday, but the quality isn’t there.

The first real standout kicks off on Wednesday morning, 2nd September. The wind goes glassy from the ESE, and you’ve got a solid 6ft SW groundswell with a 16-second period. The waves will have real punch, with moderate to strong energy (1838). This is excellent for experienced surfers – the size and power mean it’s not a beginner’s day. The water is sitting at a warm 86°F, which is a touch above average for this time of year, so you’ll be comfy in boardies.

The next gem is Thursday morning, 3rd September. Flat calm, glassy conditions with the wind dropping to zero. You’re looking at a clean 5ft SW swell, period around 15 seconds, and moderate energy (1036). The conditions will be pristine, with clean walls for a well-positioned reef and point break like Bawa.

Then we go through a quiet patch into the end of the first week and start of the second, with smaller, less consistent energy until we hit the next big window.

The absolute best run for this forecast is the stretch from Tuesday the 8th through to Thursday the 10th of September. On Tuesday morning, the 8th, we get offshore winds from the north at 6 mph, pushing into a 5ft SSW groundswell with a very long 19-second period. The energy jumps way up (2023). The afternoon gets even bigger at 6ft, and the wind turns cross-offshore from the WNW, keeping the faces clean. This is a top-shelf session for advanced surfers. The power from that long period will really set up on this exposed reef-and-point break.

Wednesday the 9th and Thursday the 10th keep the quality high with cross-off and offshore winds and consistent 6ft to 6ft SSW swell, all with strong energy. The Thursday morning session with that 6ft SSW swell and light offshore NNE wind (2171 energy) is a genuine standout – glassy, powerful, and clean.

After that, the pattern holds up through the weekend of the 12th to the 14th, but the swell size drops back a little. You’ll still get plenty of glassy and clean windows, but for the absolute best of the whole run, lock in that mid-week from the 8th to the 10th. It’s promising.

Keep an eye on the tides, as always, because that reef and point will respond to the water level, but the wind and swell windows are looking prime.

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.
