The Lowdown
Alright, Rusty here. Let's chew the fat on Bawa. This reef and point break has a taste for SW swell, and we’ve got a solid sequence coming down the pipe, but you've got to be patient.
The early part of the week, Monday the 27th and Tuesday the 28th, is pretty flat and messy. Small, short-period waves with cross-shore breezes; nothing to get excited about. Don't bother.
The first proper session to pencil in is Friday morning, July 31st. We’re looking at a 4ft swell from the SSW with a long 17-second period and the bay is glassy as a mirror. The ocean has some real energy behind it (1264). It’s clean, it’s punchy, and the point will be running nicely. The afternoon holds up too, but the morning is where you want to be for absolute perfection.
The swell keeps building. Monday the 3rd of August, we’re up to a solid 6ft SSW groundswell, glassy in the early hours. This is pushing into expert size, and with that long period, the reef will be handling some serious water. Not for the faint of heart.
The real standout session is clearly Thursday the 6th of August. A solid 7ft SSW groundswell, 18-second period, and that crystal-clear glassy morning. The energy reading hits a massive 2487 – this is the real deal. The reef will be doing its magic, shaping these long-period swells into proper barrels. Only for experienced riders. The following day, Friday the 7th, is another cracker, with 6ft and offshore winds later on. Two days of excellence.
There’s a bit of windswell and chop towards the next weekend, but we get another clean window on Tuesday the 11th of August, with a 6ft S swell and dead calm conditions to finish the run.
Since this is a reef and point setup, those long-period groundswells (all between 15 and 19 seconds) are going to produce some of the best shaped waves in the region, with longer lulls for a relaxed paddle out. The water is about average temperature for the season – nothing out of the ordinary there.
Rusty, signing off.

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.
