The Lowdown
Alright folks, Rusty here. We’ve got a solid 16-day window to look at, and it’s all about one spot. Let’s get into it.
The immediate forecast is building into a decent run, but there’s a bit of a wait for the real magic. The first few days from Thursday the 6th are surfable, but it’s a bit raw. The water is sitting at 86°, which is about normal for this time of year, so no need to stress about a wetsuit change.
We kick off Thursday morning, the 6th, at Bawa with a 7ft SSW swell. The period is a long 17 seconds, which is proper groundswell energy. The wind is a moderate cross-off from the NW, so it’s clean but has a bit of texture. The combined energy is strong at 3008. It’s a bit marginal for the average punter, but the setup is there. Thursday afternoon drops to a gentle breeze, still clean.
Friday morning the 7th looks similar, 7ft SSW with a 15-second period and a moderate cross-off breeze. The real standout on Friday is the afternoon session: the swell bumps up to 8ft from the SSW, the period stretches to a very long 18 seconds, and the wind swings offshore from the NNW. The energy jumps to 3463, and conditions are described as excellent for experienced surfers. This is a big step up.
Saturday morning the 8th is still firing with a 8ft SSW swell, 16-second period, and a light offshore breeze. The energy is 2840. It’s clean and powerful. Saturday afternoon the wind goes cross-off, but it’s still a gentle breeze and clean.
Sunday the 9th sees a bit of a drop. The swell is 7ft SSW, but the wind goes light and variable. The morning is a cross-shore, but the afternoon becomes glassy. A 7ft, 16-second swell with glassy conditions is a premium window for the experienced crew. The energy is 2086.
Monday the 10th is a step down in size to 6ft, and by the afternoon it’s a 4ft, 21-second period S swell with onshore wind. Not great.
Tuesday the 11th and Wednesday the 12th bounce back to 7ft S swell, but the wind is a persistent cross-onshore. The energy is strong (3348 and 2385 respectively), but the quality is compromised. Wednesday morning the 12th is glassy, which is a nice window for a 7ft, 17-second S swell.
Thursday the 13th is a mixed bag, but the afternoon is glassy with a 5ft, 20-second S swell. The energy is 2970. Very clean but smaller.
Now, here’s the big one. Friday the 14th is the absolute highlight of this entire run. The morning kicks off with a 8ft S swell, 17-second period, and glassy conditions. The energy is massive at 3586. Then the afternoon is the pinnacle: an 8ft S swell, 16-second period, glassy conditions, and energy at 3274. This is expert territory, but for a confident surfer, this is near-perfect. The wind is light and variable, making it glassy. This is the session to circle on the calendar.
Saturday the 15th is still good, with a 6ft S swell and glassy conditions in the morning. The energy is 1951. It tails off from there.
The second week is a bit more spaced out. Sunday the 16th is small, 4ft, and then Monday the 17th is only 5ft. The energy drops right off (1088 and 1065). Not much to write home about.
Tuesday the 18th builds back to 6ft, but the wind is onshore. The energy is 2643. Worth a look if desperate.
Then we get another promising window. Wednesday the 19th is a standout. The morning sees a 7ft SSW swell, 16-second period, and glassy conditions with energy at 4461. The afternoon is the biggest of the entire forecast: a 10ft SSW swell, 18-second period, and glassy conditions with a calm wind. The energy is an enormous 5325. This is only for experts. It’s a long-range call, so it’s promising but less certain. Thursday the 20th is still big, 8ft, but the wind is a cross-off in the morning, so it’s clean.
The run fades out from Friday the 21st, with a 8ft cross-on, and then it’s done.
Best on offer: Without a doubt, Friday the 14th at Bawa. The 8ft S swell with glassy conditions is the sweet spot. The Wednesday the 19th afternoon is the biggest and most powerful, but it’s a long-range call and it’s a 10ft monster, so only for the elite. The Friday the 14th is the most reliable high-end session.

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.
