The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up for Bawa.
This is a solid reef and point setup, very consistent, and it’s exposed to the SW. The water temp is sitting at 86°, which is pretty much bang on average for this time of year, so no surprises there.
The week kicks off quiet. Thursday and Friday are a bit of a write-off, with messy cross-onshore winds and small, weak swell. The combined energy is moderate – around 900 to 1300 (combined energy of all swells directed here) – and the wave quality is just marginal. Not worth paddling out for.
The real action starts on Saturday, the 1st of August. The morning is a standout. We’ve got a 5ft SW groundswell rolling in with a long 17 second period, and the wind is glassy. That’s clean, smooth, and the swell direction is right on the money for the optimum. This is the best session of the early run. The energy is solid at 1380 (combined energy of all swells directed here). It’s not too big, so it’s manageable for experienced surfers, and the crowds might be around, but it’s worth it.
Sunday afternoon also looks clean with glassy conditions, but the swell drops a bit to 3ft from the S. Still a nice little session if you’re keen.
The next big highlight is a few days out. Wednesday, the 5th of August, we’ve got a 5ft SW swell with offshore winds in the morning. Clean, punchy, and the energy is jumping to 1980 (combined energy of all swells directed here). That’s a solid step up.
Then Thursday, the 6th of August, is the real gem. The swell hits 7ft from the SSW, with a 17 second period and morning offshore winds. The combined energy is 2828 (combined energy of all swells directed here), which is strong. This is a proper groundswell, and it’ll be firing at the point. This is for advanced surfers only – it’s big enough to be a handful. The following days keep pumping with 6ft to 7ft swell and clean offshore winds right through the weekend.
After that, the swell backs off a little into the second week, but there’s still some decent energy around. The 10th of August has a 6ft SSW swell with light offshore winds, another good clean morning. The energy is 2352 (combined energy of all swells directed here), making it a worthy session.
The very end of the window gets a bit messy again with a strong, cross-onshore S swell on the 12th and 13th, and the quality drops. The energy is high, but the wind is choppy, so it’s more of a kite session than a tidy paddle.
Overall, the standout is Saturday, 1st August for the glassy, clean conditions, and Thursday, 6th August for the size and power. 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.
