The Lowdown
Alright, this is Rusty, and I’m looking at what’s cooking for the next stretch of days. The good news? There’s plenty of action to talk about, and a couple of absolute standouts that are worth getting excited about.
We’re kicking off straight away with no quiet start. The main draw for the whole outlook is Bawa, a reef and point break that’s very consistent and exposed to the SW. The water is sitting at 86°, which is pretty normal for this time of year, so nothing wild there.
Things get going on the morning of Sunday the 19th. It’s a bit cloudy, but the wind is glassy from the SE at a tiny 3 mph. Swell is a clean 4ft from the SSW, with a nice 13-second period. The combined energy is moderate (536). This is a solid, clean start for the weekend.
Monday the 20th and Tuesday the 21st are the first real standout window. Monday morning sees a jump in size to 6ft from the SSW, with a very long period of 17 seconds. The wind is light offshore from the N at 3 mph. The energy is strong (1790). This is not for beginners – it’s in the advanced zone, but for the experienced crew, this is a proper groundswell hitting a reef and point, which is perfect. It’s clean. Tuesday morning is similar, with a 5ft SSW swell, 15-second period, and glassy conditions from the E. The energy is still strong (1149). This is the best of the near-term.
We do have a bit of a lull after that. Wednesday the 22nd is smaller at 4ft, and Thursday the 23rd drops further to 3ft with onshore winds and a short period. Thursday afternoon is a write-off. Friday the 24th builds back a bit, but the period is lower.
The next big highlight comes on Thursday the 30th of July. The morning is looking excellent. The wind is glassy from the NE at 3 mph, and the swell is 3ft from the SSW, but with a very long period of 20 seconds. This is a groundswell, and the energy is strong (1182). This is a session for the point break connoisseurs.
But the absolute standout of the whole forecast is the Monday the 3rd of August. The morning is packing a 7ft SSW swell with a 19-second period, and the wind is a clean offshore from the ENE at 6 mph. The energy is very strong (3363). This is big, powerful, and perfect for a reef and point. It’s expert territory only. The afternoon is even a touch bigger at 7ft, with glassy conditions from the S. This is the one to circle on the calendar. It’s a long way out, but the signs are incredible.
Crowds at Bawa can be a problem sometimes, so for the Monday the 3rd session, you’ll want to be early.
Overall, the near-term is solid, but the long-range offering on the 3rd of August is the real gem. Keep your eyes on that.

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.
