The Lowdown

Alright folks, Rusty here. Let’s have a proper look at what’s coming down the pipe for the next couple of weeks. It’s a bit of a slow burn, but once it gets going, there are some absolute crackers waiting for you.

First things first, the water is sitting at a warm 86°, which is about average for this time of year, so no surprises there. The main player in town is Bawa, a reef and point set-up that’s very consistent and exposed to the south-west swell. It’s an advanced wave, and with the crowds being only sometimes an issue, you’ve got a fair chance of getting some quality ones to yourself.

The first few days are nothing to write home about. Monday the 7th through Wednesday the 9th have a bit of swell around 2ft to 5ft, but the wind is onshore or cross-onshore, so it’s messy and not worth paddling out for. The combined swell energy is moderate, sitting between 800 and 1227, but the wind just kills it.

Now, Thursday the 10th morning is where things get interesting. The wind goes glassy, dead calm, and the swell bumps up to 5ft from the SSW with a period of 16 seconds. This is a solid groundswell, and combined energy jumps to 1431, which is a nice moderate push. This will be clean, lined-up, and proper. This is your standout morning for experienced surfers. The afternoon gets a bit of a cross-shore wind, but the morning window is the one.

Friday the 11th still has some size, 5ft to 6ft, but the wind is cross-shore or onshore again, so not prime. The real power shows up on Saturday the 12th afternoon, with a 7ft SSW swell, a period of 19 seconds, and combined energy screaming at 3615. That’s a serious amount of energy. The catch? The wind is cross-onshore and choppy, so the wave face is going to be lumpy. It’s still a powerful groundswell, but the conditions will be testing.

The swell stays strong through Sunday the 13th and into the start of the following week, around 6ft to 7ft, but the wind remains stubbornly cross-onshore. The quality just isn't there for long stretches, with lots of marginal days.

But hang in there, because the second half of the week shines. Wednesday the 16th morning is another glass-off morning. The wind is dead calm again, with a 5ft SSW swell and a 14-second period. The combined energy is at 1590, and these conditions will be excellent. It’s a bit smaller than the earlier peak, but the clean conditions make it a joy.

Then you get a nice run from Thursday the 17th afternoon through to Saturday the 19th morning. The wind switches to cross-offshore or glassy, and the swell settles into the 5ft to 6ft range. Thursday the 17th afternoon has a 6ft SSW swell with a 16-second period and combined energy of 2090, and the wind is clean. Friday the 18th morning has a 5ft SSW swell with a 15-second period, and again, clean with a light offshore. And Saturday the 19th morning is glassy again, with a 3ft clean SSW swell – a long-period groundswell that will be a dream for the point break.

The last few days from the 20th to the 22nd see the swell holding around 5ft to 7ft, but the onshore wind makes a comeback, so it’s back to marginal conditions.

Best on offer: Thursday the 10th morning and Wednesday the 16th morning – both glassy, clean, and with a decent groundswell running. For a bit more size, the Thursday the 17th afternoon session with the offshore wind is also a beauty.

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.
