Table - best surf conditions forecast for Bawa over the next 16 days.
Alright, this is Rusty. Let’s get into it.
There’s a solid run of surf on the horizon for Bawa, and the setup is looking really promising for the more experienced crew. The combined swell energy is moderate to strong throughout, ranging from 434 up to over 2100, so there’s plenty of push in the water. The water temp is sitting at 86°, which is bang on average for this time of year, so nothing unusual there.
The first real standout is Wednesday morning, July 15. That’s the one to circle. We’re looking at a clean 5ft SSW swell with a 16-second period, dead calm wind, and glassy conditions. The combined energy is strong at 1358. This is a proper groundswell, and with that long period, it’s going to hold up beautifully on the reef and point setup at Bawa. It’s advanced territory, but if you’ve got the skills, this is the session.
Thursday morning, July 16, is also clean with another 5ft SSW swell at 15 seconds, glassy winds, and combined energy at 990. It’s very good, but Wednesday is the bigger call.
The following week, there’s a standout on Monday morning, July 20. This one pumps up to 6ft from the SSW with an 18-second period, and combined energy spikes to 2107. Winds are light offshore from the north, so it’ll be clean and powerful. That’s a big swell, over 5ft, so it’s not for beginners, and over 8ft it’s not, but at 6ft, it’s solid for experienced surfers. Expect some serious energy.
Tuesday morning, July 21, keeps the quality going with 5ft SSW swell, 15-second period, and glassy conditions. Combined energy is 1146. That’s another excellent session.
Later in the period, Saturday morning, July 25, brings a 2ft S swell with a very long 21-second period. Combined energy is 1104. That’s a long-period groundswell, which can be a bit straight at beach breaks, but at Bawa’s reef and point, it’s going to line up nicely. Winds are calm, glassy. It’s clean, but the swell is smaller, so it’s more of a grovel session for the connoisseurs.
Sunday morning, July 26, has a 4ft SSW swell at 16 seconds, with light cross-offshore winds and combined energy of 1099. That’s clean and fun.
There are no gaps in this forecast – Bawa has surf on offer every day, but the mornings are consistently the best. The afternoons often get a bit of onshore or cross-shore wind, which knocks the quality back. Stick to the early ones.
Overall, Wednesday July 15 and Monday July 20 are the two true standouts. Clean, powerful, and lined up perfectly for the break.
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.
