The Lowdown

Alright, this is Rusty checking in.

Alright, we’re looking at Bawa and it’s a bit of a mixed bag. This spot is a reef and point break, very consistent, and it holds a lot of swell. The water temp is sitting at about 86°, with an anomaly of plus 1°, so it’s pretty much bang on average for this time of year. The wait is on for the first good window.

The first few days from Monday the 10th are a write-off. We’ve got risk of thunderstorms, cross-onshore winds, and the wave comment is calling it marginal. No point suiting up for that.

Things start to get interesting on Wednesday afternoon the 12th. The wind goes glassy, and we’ve got a solid 6ft swell from the south at 16 seconds. The combined swell energy is sitting at 1840 (moderate). The conditions are described as excellent for experienced surfers, so this is when I’d start paying attention. Thursday morning the 13th is also okay, but the wind goes light cross-shore.

The real standout of this whole outlook lands on Friday afternoon the 14th. We get glassy conditions again, with a clean 6ft south swell at a solid 16 seconds. The energy is 1794 (moderate), and it’s described as excellent. Saturday morning the 15th is also glassy with a similar 5ft S swell at 14 seconds. For experienced guys, these are the prime windows. Keep in mind the swell coming from the south (optimum for Bawa is SW), and with periods around 14-16 seconds, this groundswell will have some serious push and shape, especially on a point.

The energy builds again heading into the second week, with Tuesday the 19th seeing some of the biggest swell of the period. Wednesday afternoon the 19th has a 10ft SSW swell with glassy winds – that’s a big, powerful wave. Combined energy hits 4697 (strong). That is only for experts, and the risk of thunderstorms is there. Then Thursday the 20th afternoon cleans right up with zero wind and a 8ft SSW swell. That is another serious session for the crew with the right gear.

Later on, Saturday the 22nd has some lovely glassy mornings and afternoons with a 6-7ft SSW swell, keeping the fun going. The surf starts to get a bit ragged toward the 23rd and 24th with onshore winds moving in.

For the absolute best on offer, I’m locking in Friday afternoon the 14th for the clean, glassy conditions and that solid, long-period swell. The second standout is Wednesday afternoon the 19th if you’re an expert looking for size and power.

This is Rusty, signing off.

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.
