Table - best surf conditions forecast for Bawa over the next 16 days.
Alright, Rusty here. Let's get into it.
We’ve got a long stretch coming up and the good news is there’s surf pretty much right through the sixteen days at Bawa. It’s a reef and point set-up, exposed to the SW, and it’s very consistent. The water temp is sitting at 86°, which is about 1° warmer than normal for this time of year, so it’s a touch on the warm side but nothing too wild.
The opening week is alright, but it’s not firing on all cylinders. The real standout window kicks off around Thursday, July 16th. That morning you’re looking at head-high, 6ft SSW swell with a 15-second period, and it’s going to be glassy with a light NE breeze. That’s clean, lined-up, proper reef-point waves. The combined energy is strong at 998 (moderate wave energy), and this is the pick of the bunch for the first week. The following morning, Friday July 17th, is also glassy early with a 4ft SW swell, 16-second period, and light E wind. Another really good call.
Jumping into the second week, Saturday July 18th holds up with glassy 5ft SW swell in the morning and a clean cross-offshore breeze in the afternoon. The real standout, though, is Sunday July 19th. The morning is dead calm, glassy, with a 3ft SSW swell and a very long 16-second period. The combined energy is 1011 (moderate wave energy), and the conditions are described as excellent for experienced surfers. That’s a classic early morning glass-off with a long period groundswell – perfect for a point break like Bawa. The long period means it might break a bit straight at a beach break, but on a reef and point, it’ll be a dream.
The following week has some more promising windows. Monday July 20th morning is glassy with 4ft SSW swell, and Tuesday July 21st is dead calm and glassy with 5ft SSW swell. Then Wednesday July 22nd morning has a tiny 3ft swell but with a very long 20-second period, combined energy of 1089 (moderate), and glassy conditions. It’s a special one for the experienced crew. Thursday July 23rd and Friday July 24th both offer glassy mornings and clean cross-offshore afternoons with 5ft SW swell and 16-18 second periods. The energy is strong (1500 for Thursday morning), and the conditions are excellent. The crowds at Bawa can be a thing sometimes, so get in early for the cleanest ones.
Overall, the best of the best is that Sunday July 19th morning glass-off, followed closely by the series of glassy mornings from July 16th through the 18th, and then again from the 22nd to the 24th. The surf stays rideable for most of the run, but those standouts are the ones to circle on the calendar.

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.
