The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for the Bawa (reef and point) region.

The swell window is open, but it’s a slow burner for the first few days. Thursday the 10th and Friday the 11th are a write-off for quality surf – the wind is onshore or cross-on, the waves are messy, and it’s just not worth paddling out. You’ll want to wait. Saturday the 12th is a bit of a mixed bag; the morning is choppy with a cross-on breeze, but the afternoon shows some promise. The swell builds to 7ft from the SW with a long 19-second period, and the wind goes light and cross-shore. The energy is strong (3635), but the wave quality is still a bit marginal. Not the standout, but a sign of things to come.

The real standout window kicks off Sunday morning, September 13th. This is the one to circle on your calendar. We’ve got a solid 8ft SW groundswell with a 17-second period, and the wind is glassy – absolutely dead calm. That’s the recipe for clean, powerful lines. The combined energy is pumping at (3379). This is advanced-level surf, so if you’re not comfortable with overhead waves, give it a wide berth. But for the experienced crew, this is as good as it gets. The water is a warm 86°F, which is about 2°F warmer than average for this time of year, so you’re in for a tropical session.

After Sunday morning, the wind gets a bit onshore again, but the swell sticks around in the 5ft to 7ft range. Monday and Tuesday are okay, but nothing special. Then Wednesday morning, September 16th, throws up another chance. The swell drops to 5ft from the SSW, but the wind goes glassy again. It’s a smaller, cleaner day for those who want the quality without the heavy size.

The second week from the 18th onward has some decent morning windows. Saturday the 19th and Sunday the 20th mornings are looking tidy – glassy and clean conditions with 4ft to 7ft SSW swell. The wind is light and offshore, so the waves will be well-shaped. The long-period groundswell will favour the point break setup here, giving you longer, more drawn-out rides.

By the 22nd and into the 24th, the swell drops off a bit, but the wind stays clean and offshore, offering smaller, fun-sized waves in the 3ft to 4ft range. It’s not a power session, but it’s clean and rideable.

Bottom line: Don't bother paddling out until Saturday afternoon at the earliest. The absolute best bet is Sunday morning, September 13th, for the biggest, cleanest, and most powerful waves. The second-best window is Wednesday morning the 16th, and then the weekend of the 20th for some clean, fun waves.

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.
