The Lowdown

Alright crew, Rusty here. Let’s break it down.

We’re looking at a solid stretch of waves at Bawa. This reef and point break is in for a treat, picking up a nice long-period SW groundswell that’s got some real grunt. The water’s sitting at 86°F, which is about average for the time of year, so nothing out of the ordinary.

The best early window is Thursday, September 3rd. The morning is looking prime with a clean 5ft swell from the SW, a 15-second period, and a light offshore breeze from the north. That’s the kind of setup that’ll have you smiling from ear to ear. The combined energy is moderate at 1054, and with the wind off the land, it’s going to be silky smooth. The afternoon gets a bit messy with a cross-shore, so get in early.

Friday, September 4th, is another cracker. The morning is dead glassy – zero wind – with a 4ft swell from the SSW. It’s a touch smaller, but when it’s that clean, it’s a dream. The energy is moderate (681), and those 13-second intervals between sets will make paddling out a breeze. This is a perfect session for a mid-length or a fun board.

The following week keeps the goods rolling. Monday, September 7th morning is clean with a light offshore and a 4ft SSW swell. Then Tuesday, September 8th morning gets interesting: a 4ft swell but with a very long 18-second period (1089 energy). That’s a proper groundswell. It’s small, but at a point break like Bawa, those long-period lines will wrap in like a dream.

The big one, the one you need to mark on your calendar, is Wednesday, September 16th. This is a serious day. We’re talking a 7ft SSW swell with a 20-second period and glassy conditions in the morning. The combined energy is a massive 4645 (strong), which is a ton of power. It’s going to be big, pushing 8ft in the afternoon, so this is strictly for the experts. The wind stays glassy all day, with a light SW breeze in the afternoon keeping it smooth. If you’re skilled and comfortable with heavy water, this is the day to be out.

There are no real gaps in the surf here; it’s a very consistent run. The only rough patch is Saturday, September 12th, when a strong westerly wind (25 mph) and heavy rain will trash the surface. The swell is still there, but it’ll be a messy, choppy mess. Best to take that day off.

Crowds at Bawa are listed as "sometimes", so expect a few heads on the peak, but it’s not a packed house. The reef and point setup loves these long-period swells (15-20 seconds), bending them into clean, peeling lines. The beach breaks might get a bit walled-up, but here, it’s a dream.

Get out there and enjoy the run.

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.
