The Lowdown

Well, grab your board and let's have a look at the Bawa stretch. It’s a reef and point set-up, exposed to the southwest, and honestly, the water’s sitting at 86° right now, which is just a touch warmer than usual for this time of year – nothing crazy, but you'll notice it’s not cold.

The next week and a half are going to be a bit of a waiting game. The swell is there, but a lot of it is tangled up with onshore breezes and iffy conditions. The energy is strong, though, with that combined swell bouncing between 2226 and 3162 through Monday and Tuesday, but it’s all a bit messy. We're not looking at a clean paddle-out until things settle.

Your first real window comes up on the morning of Thursday, the 3rd. We get a light offshore N wind, and the swell’s still a solid 5ft from the SW, with about 1054 units of energy behind it. The period’s around 15 seconds, so there’s some punch. It’s clean, and it’ll be the first time it feels worth paddling out. It’s not huge, but it’s clean and better than what we’ve been dealing with. Friday afternoon, the 4th, also looks promising – 4ft, and it’s glassy. It’s a bit smaller, but those clean conditions can make up for it.

The standout, though, is looking like Tuesday morning, the 8th. It’s glassy with a light NNW offshore breeze, and while the swell dips a touch to 3ft, the period jumps back up to 18 seconds. That’s a proper groundswell, and with that long period, it’ll be holding up nicely on this reef and point. The energy is a bit lower at 844, but the quality will be there for the experienced crew.

After that, things start to build again. Wednesday the 9th and Thursday the 10th bring more size, with the swell back up to 5ft and 6ft, and we get some clean, offshore and cross-off conditions. Thursday morning, the 10th, looks like the pick of the week – 6ft of SSW swell, clean, with a light WNW cross-off breeze and 1623 units of energy. That’s got some push and should be lining up nicely on the point.

Now, about that second week – it’s a bit more of a promise than a guarantee. The size hangs around, peaking on the 14th with 7ft of SSW swell and a period of 17 seconds, but it’s mostly got a southerly wind on it, making it messy and onshore. The energy is big, around 2772, but it’s not going to be pretty. That Thursday the 10th is the day to be out. After that, it’s about checking the forecasts and hoping the wind swings around.

So, get on it Thursday the 3rd, but really, pencil in the 8th and 10th of September. That’s where the magic is. For now, keep it clean, respect the reef, and enjoy that warm water.

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.
