Table - best surf conditions forecast for Bawa over the next 16 days.
Alright, let’s switch to feet and Fahrenheit. Rusty here again, talking Bawa.
This is a reef and point break, very consistent, and it loves a southwest swell. Water temp is about 86°, which is a touch warmer than average for this time of year – nothing crazy, just a little extra warmth.
The next couple of weeks have some drama. From Saturday the 11th through to Tuesday the 15th, it’s mostly onshore winds and stormy vibes. Swell is running 3 to 4 feet, but the wind is junk. The wave energy is moderate to strong (925 to 1527), but it’s not worth paddling out for.
Then Wednesday the 15th morning turns it on – glassy conditions, 5-foot SSW swell, 16-second period, energy at 1352. That’s a proper groundswell, and the reef and point will be handling it perfectly. This is for experienced surfers only. The best morning of the first week.
The big one is Monday the 20th morning. Glassy, 6-foot SSW swell, 17-second period, and the energy is pumping at 2336. That’s a powerful, clean wave. The reef will be holding it together. Expert territory again, but it’s the best of the whole forecast.
Tuesday the 21st morning is also glassy with 5-foot SSW swell, 15-second period, energy at 1245. Still excellent for experienced surfers. Then we get a little lull before Thursday the 24th morning – glassy, 3-foot SW swell, long 18-second period, energy at 1035. That’s a fun size for more people.
Saturday the 25th morning has a clean offshore wind from the NNW, 3 to 4-foot SW swell, 16-second period, energy at 1320. The afternoon is also clean with a cross-offshore breeze, 3-foot SSW swell, 18-second period. Very tidy.
The standout is Monday the 20th morning – glassy, 6-foot groundswell, massive energy, and the reef and point will be doing what they do best. Wednesday the 15th morning is the top pick for the first week.
Rusty out.

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.
