The Lowdown
G'day, Rusty here, and I've got a good look at what's coming up for Bawa over the next couple of weeks. This is a reef and point set-up that's exposed to the southwest, so it's a real magnet for any proper groundswell that rolls in. Don't let the "advanced" rating scare you off – if you've got the chops, this is where the magic happens.
We kick things off with a blinding start. On Saturday, the 29th of August, the morning session is a dead-set winner. We've got a clean 5ft SSW swell running, and the wind is absolutely glassed out – zero, nada, nothing. The water's sitting at a warm 86°, which is spot on average for this time of year. The combined energy is moderate (1017), and with that 14-second period, it's proper groundswell. This is a ripper for experienced surfers.
Unfortunately, that's the only true standout in the near-term. The rest of that weekend and into the start of the week is a bit of a mixed bag. Sunday the 30th sees the swell drop to 3ft with a very long 21-second period, but the wind is cross-shore, making it a bit messy. The energy is moderate (976), but it's not the clean stuff we want.
By Monday the 31st, the swell is back up to 6ft from the SW, and the energy is strong (2228). The wind is cross-onshore though, so it's going to be a bit lumpy. It's a solid 3-out-of-10 day, but not the best conditions.
Tuesday the 1st of September is a similar story. The swell is even bigger, 8ft, from the SW with very strong energy (3162). That's getting into expert-only territory, but again, the cross-onshore wind is going to chop it up. Wednesday morning, the 2nd of September, is a real tease. The swell drops back to 6ft, but the wind goes glassy again. The energy is still strong (1843), and the description says "excellent surf conditions for experienced surfers." That's a solid 4-out-of-10 morning, but it's a short window before the wind turns onshore again.
The first week of September is a grind. After the 2nd, the swell backs off and the wind is a constant battle. It's not a classic run, but the consistency of this spot (very consistent) means it's only a matter of time before the next pulse.
Now, here's the real story. The long-range forecast is lighting up. The standout is the morning of Thursday, the 10th of September. We've got a 5ft SW swell with a 17-second period, the wind is offshore from the NNE, and the combined energy is strong (1221). The description says "excellent surf conditions for experienced surfers." That's a 4-out-of-10 winner. It's a bit far out, so don't lock it in just yet, but it's got my blood pumping.
Then, Friday the 11th of September could be the pick of the whole run. The morning is a dream: 6ft SW swell, a 16-second period, and glassy conditions with a light NE breeze. The energy is very strong (1643). That's another 4-out-of-10 morning, and if that holds, it's a session you'll be telling your mates about. The afternoon is a bit onshore, so get out early.
After that, the surf settles down a bit through the second weekend. The swell holds around 5ft to 6ft, but the wind is mostly cross-onshore or onshore, so it's a bit of a bumpy ride. It's still surfable, but it's not going to be the clean, lined-up waves of the 10th and 11th.
So, the plan is simple. If you're an experienced surfer, get on it this Saturday morning, 29th August, for the glassy start. Then, keep your eyes peeled for the 10th and 11th of September – those are the ones that could be absolute crackers. The rest of the time, it's a bit of a wait and see, but Bawa is a consistent spot, so it won't be flat for long.
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.
