The Lowdown

G'day, I'm Rusty. Let's have a look at what's on the cards for Bawa (Bawa). We've got a solid run of SSW groundswell heading our way, but the wind is going to be a real talking point. The water temp is about average for this time of year.

Starting Thursday the 20th of August, we've got a big pulse of energy pushing in. The combined swell energy is strong, at 4097, with a 10 ft SSW swell and a very long 16-second period. That's a lot of water moving around, but the wind is a cross-on from the SE at 9 mph, which is going to make it choppy. It's a powerful, expert-only wave at this size, but the conditions aren't doing it any favours.

Friday the 21st still has a solid 7 ft SSW swell, but the wind drops right off to a light 3 mph cross-on. It's still marginal, but that's a big improvement. The period remains a long 15 seconds, so there's plenty of energy in the water (2446 combined).

Saturday the 22nd is a bit of a mixed bag. The swell is still 7 ft, and we get a light 3 mph cross-shore wind in the morning. That's a good sign, but the wave comment still says marginal. The energy is still very strong at 2512.

Sunday the 23rd sees the swell drop a touch to 6 ft, and it's still a long period 14-second groundswell. The wind is light cross-on in the morning, so it's worth a look, but the quality is still described as marginal.

Monday the 24th, the swell bumps back up to 6 ft with a very long 17-second period. That's a lot of energy (2034), but the wind is a light cross-on. It's still marginal.

Tuesday the 25th and Wednesday the 26th, the swell continues to ease. Wednesday the 26th morning is the first real standout in the near term. The swell is 4 ft from the SSW with a 13-second period, the combined energy is a moderate 622, and the wind goes glassy. That's a clean, fun-sized wave for a more experienced surfer.

Thursday the 27th, the swell drops to 3 ft but the period goes absolutely massive at 20 seconds. The combined energy is strong at 1512, and we get a light offshore wind in the morning. A long-period swell like this at a reef and point break like Bawa is a beautiful thing. The sets will be long and clean, but the paddling will be easier. It's a marginal call, but the ingredients are all there.

The next big highlight is Sunday the 30th of August. The morning glass-off with a 3 ft SSW swell and a 22-second period is a dream scenario. The combined energy is 1362, so there's plenty of push for the size. That's a clean, lined-up wave for experienced surfers.

Moving into the last week, Monday the 31st of August sees a big jump in swell back to 8 ft, with a very strong combined energy of 3897. The wind is light cross-on, so it's a big, powerful wave.

Then we get to Tuesday the 1st of September. This is the standout of the entire run. The morning is glassy, with a 8 ft SW swell and a 17-second period. The combined energy is a massive 3207. This is a serious, powerful groundswell with clean conditions. It's an expert-only wave, but for those who can handle it, this is the one to circle.

The swell fades from there, with Wednesday the 2nd at 7 ft and Thursday the 3rd dropping to 4 ft. The final note is Friday the 4th of September morning, with a 4 ft SSW swell, a 14-second period, and glassy conditions. The combined energy is 642. A clean, small day to finish off.

So, the best of the best is Tuesday the 1st of September morning for the experts. The 30th of August and the 27th of August are also solid windows for the more experienced crew. The winds are the main issue for the first week, but patience will pay off.

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.
