The Lowdown
Alright mates, Rusty here. Let’s get into it. We’ve got one main spot firing over the next couple weeks, and it’s looking like a proper run of solid, consistent groundswell for the experienced crew. Gotta wait a bit for the best of it, but the pattern is setting up nicely.
The standout session is looking like Sunday, August 10th. Morning brings a 5ft SSW groundswell with a 15-second period, and the wind goes completely glassy. It’ll be dead clean. The combined energy is a solid moderate 1350. The afternoon is just as sweet, 5ft SSW swell, a little less period at 14 seconds, but still glassy. That’s the pick of the whole outlook—just you and the ocean, no wind, nice lines rolling in.
Before that, the first week is a mixed bag. Sunday, August 2nd morning is the first real go. We’ve got a 5ft SSW groundswell with a long 16-second period, and a glassy 5 km/h NNE breeze. Water sits at a warm 86°F, with a small anomaly, so pretty average for the time of year. Combined energy is a solid moderate 1347. It’s an advanced reef and point set-up that is very consistent, so expect powerful waves for experienced surfers. It can get crowded sometimes, but that’s the price of a spot this good.
From August 3rd through the 8th, there’s a rough patch. Swell sticks around, mostly 5ft to 8ft, but wind gets messy—cross, cross-off, and fresh breezes, plus those risk of thunderstorms hanging about. On Tuesday, August 5th morning, we get a clean 5ft SSW swell with a decent 15-second period, and fresh offshore wind, which is about as good as that stretch gets. Combined energy is a strong 1928, so plenty of push, but it’s a full-on session for experts only.
Later on, Saturday, August 15th morning looks promising again. A 5ft S swell at 17 seconds, glassy with just a light breeze. Combined energy of 1707, clean lines, clearing skies after. That’d be a solid runner-up to the 10th.
Forget the 11th through 14th—mostly onshore junk from the south, short and choppy with cross-onshore wind. Not worth paddling out for unless you’re keen for a thrashing.
This spot is for experienced surfers only. When the swell jumps over 7ft on a few days, you’re looking at serious power. The long period groundswell (15-18 seconds) means better shaped waves and more energy between sets, but it can break a bit straight at times. Still, for those who know what they’re doing, there’s a lot to love.
A good outlook overall. Might not be perfect every day, but the quality days are real quality.
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.
