The Lowdown
Alright mate, Rusty here, looking at the Bawa forecast for you.
The next couple of days are gonna be a bit frustrating. There's some solid swell around, but the wind's gonna mess with it through the weekend. You're gonna have to be patient for the really good stuff.
Starting Saturday the 12th, the swell's here, but that 9 mph cross-onshore from the ESE is making it a choppy mess. The wave energy is moderate but building. Sunday the 13th is more of the same with a risk of thunderstorms and that cross-onshore wind. The swell is there, around 8ft, but the conditions are junky. Don't bother paddling out.
Now, Monday the 14th is where it starts to get interesting. The wind shifts to a light NNE, turning cross-offshore. The swell drops a touch to 6ft, but it's a clean, lined-up SW groundswell with a solid 15-second period. This is your first good window, especially in the morning.
But the real standout, the one you’ve been waiting for, is Tuesday the 15th. The morning is completely glassy with a light offshore from the north. The swell is a nice 6ft from the SSW with that long 15-second period. The energy is strong, and the report says it's "glassy." That's as clean as it gets, folks. The afternoon stays glassy, too. This is the pick of the whole forecast. No crowds to worry about with that glassy offshore.
Wednesday the 16th and Thursday the 17th keep the good times rolling, with glassy mornings. Wednesday's swell is a bit smaller at 5ft, but still super clean. Thursday morning is a beauty with a 6ft, 17-second SSW swell and glassy conditions. That's a lot of energy for a clean swell. It’s excellent.
Things start to fade from Friday the 18th as the onshores return. We get a few days of mediocre conditions through the weekend of the 19th and 20th.
For the second week, there are two more very promising windows. Monday the 21st morning is completely glassy with a clean 6ft SSW swell. Wednesday the 23rd is another classic with a 5ft swell and a light offshore from the north in the morning, followed by a clean cross-offshore in the afternoon. Thursday the 24th is smaller at 4ft but glassy with a nice SW swell.
After that, the energy fades right out. The final three days from Friday the 25th through Sunday the 27th are looking small and weak, with onshore winds.
To wrap it up: you've got two real standouts. The first is the glassy morning of Tuesday the 15th. It's clean, powerful, and perfectly shaped. The second is the glassy morning of Thursday the 17th for that extra-long period energy. That's your call. Get out there.
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.
