The Lowdown

Alright, this is Rusty. Let's talk about the waves coming up at Bawa.

The water temperature is sitting at a warm 86°, which is pretty much bang on average for this time of year, so no surprises there. We've got a solid run of surf ahead, but the standout window is looking like the first week of September, with a couple of real gems.

We kick off on Thursday, August 27th. Thursday morning is the real deal to start. The swell is a clean 4 ft from the SSW, with a period of 19 seconds – that's a long-period groundswell packing some serious energy (1870). The wind is dead calm, glassy as can be. This is fantastic for experienced surfers; the waves will be well-shaped and powerful, but at this size, the long period might make it a bit fat on the beach, but Bawa is a reef and point setup, so it's going to be lined up. Thursday afternoon gets a bit cross-on, so it'll get bumpy.

Friday the 28th and Saturday the 29th see the swell size bump up, but the wind gets messy. Friday morning has a solid 7 ft SSW swell, but the cross-on wind from the ESE will chop it up. Saturday is similar, with the wind making things marginal. You'll want to be picky.

Sunday the 30th is a bit of a lull, with the swell dropping to 3 ft and a very long period of 21 seconds. The energy is moderate (1008), but it's glassy on Sunday morning, so there might be the odd clean but weak set.

Now, here's the good stuff. The action really picks up on Monday, August 31st. The morning is glassy, with a 6 ft SW swell and a very solid 18-second period. The energy is strong at 2386. This is excellent for experienced surfers.

Then, Tuesday, September 1st, is the standout. Tuesday morning is glassy, with a 8 ft SW swell and a 17-second period. That's a 8 ft groundswell with a massive 3131 energy reading. The wind is glassy. This is top-tier, powerful, and clean surf, but at this size, it's for experts only. It's going to be a big, long-period swell, and Bawa is a reef and point, so it will handle it beautifully.

Wednesday, September 2nd, is still good. The morning is glassy again with a 6 ft SW swell, but the energy is dropping slightly to 1852. Still excellent conditions.

We get a bit of a drop-off from Thursday, September 3rd, through Saturday, September 5th. The swell drops to around 5 ft, but it's still glassy in the mornings, so the waves will be clean and fun, just not as powerful.

The final bit of the outlook is interesting. From Sunday, September 6th, right through to Friday, September 11th, we see a run of cleaner conditions. Sunday the 6th has glassy mornings with a 5 ft SSW swell, and Monday the 7th has a nice offshore wind from the north. The swell is a little smaller, but the wind is favourable. The standout in this second week is Thursday, September 10th. It's glassy calm with a 3 ft SSW swell, but the period is a very long 16 seconds, giving it a surprising amount of energy (1094) for the size. It'll be clean and fun. Friday the 11th also has a clean, offshore wind with a 5 ft SSW swell.

The best of the best is hands down Tuesday, September 1st morning. That 8 ft, glassy, long-period groundswell is the one to wait for. Get on it.

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.
