The Lowdown

Alright folks, Rusty here. Let’s talk about Bawa. This is a reef and point break, and it’s exposed to the swell, meaning it picks up plenty of energy. It’s a very consistent setup, which is always a good sign.

Right now, the early part of the forecast is a bit of a write-off. Saturday afternoon is messy with a cross-onshore wind and poor conditions. Sunday doesn’t look much better either, with similar cross-onshore winds and marginal surf. You’ll want to sit tight through that.

Things start to turn around on Monday morning, the 7th. We’ve got a clean, cross-offshore wind and a solid 4ft swell from the SSW. The combined swell energy is moderate (895), and the period is a long 15 seconds – proper groundswell. This is a good sign for a reef and point setup like Bawa, as it will wrap in nicely. It’s a promising start to the week.

Tuesday morning, the 8th, is a real standout. Glassy conditions, a 2ft swell from the SSW, but with a very long period of 20 seconds. The combined energy is moderate (1087). This is the kind of clean, lined-up surf that makes a reef point so special. The swell is small, so it’s not going to be a big day, but the quality will be there for experienced surfers.

The following week builds in size. Wednesday morning, the 9th, and Thursday morning, the 10th, are both glassy with 5ft SSW swells. The combined energy is getting stronger – around 1270 and 1381 respectively. These are excellent conditions for experienced surfers, with those long-period swells providing plenty of push.

By the 12th of September, Saturday morning brings another glassy session with a 5ft SW swell and a combined energy of 1598. It’s a solid setup.

The second week sees the swell really kick in, with heights hitting 6ft to 7ft. Wednesday morning, the 16th, is glassy with a 6ft SSW swell and a combined energy of 1750. Then Saturday morning, the 19th, is glassy again with a 7ft SSW swell and a combined energy of 2280. These are the biggest swells of the period, and they’re coming in clean. Because it’s a reef and point, the long period (15-16 seconds) will create some beautiful, powerful lines.

Crowds are possible here sometimes, so be aware, but with this level of consistency and quality, it’s worth it.

Water temperature is around 86°, which is about normal for the time of year.

The best on offer is the glassy, long-period Tuesday morning on the 8th for quality, and the bigger, clean swells on the 16th and 19th for power. It’s a solid run.

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.
