The Lowdown

Alright, crew, Rusty here. Let's look at the next couple weeks. There's definitely some juice in the water, but we're gonna have to be smart about when we paddle out.

The first day, Tuesday the 18th, is not great. Swell is 5 ft but bumpy, with cross-onshore winds making for a choppy surface. There's a lot of energy, but it's not clean. We're just gonna have to wait for the wind to ease off.

Things go from zero to hero on Wednesday morning, the 19th. It's dead glassy, flat calm, with a solid 8 ft of swell from the SSW with a long 18-second period. The energy is strong, and the conditions are clean. This is a big, powerful groundswell and it's going to be breaking with authority at Bawa (Bawa). This is a session for experienced surfers only, but it's going to be special. This is your standout.

The rest of the week is a letdown. Thursday the 20th has more size, up to 10 ft, but with a shorter period and onshore winds, it's going to be a windy, jumbled mess. Not worth it. Friday the 21st sees a drop in size, and the morning is still cross-onshore. The afternoon turns glassy again with 6-7 ft surf, but it's a step down in quality from Wednesday. The weekend, the 22nd and 23rd, looks poor. Stronger winds and deteriorating conditions, while the swell backs off and loses its power. We'll have to let that pass.

We then slide into a flat spell from the 24th to the 28th. The swell drops to just 3-6 ft, and the energy is weak. The waves will be small, weak, and mostly junky. It's a quiet stretch, and you might as well leave the board in the car.

But there's light at the end of the tunnel. Saturday the 29th kicks off with a glassy morning and a clean 5 ft swell from the SW with an 18-second period. Feeling promising. Then Sunday the 30th is looking like another solid one. Another glassy morning, and the swell has bumped up to a solid 7 ft from the SW at 17 seconds. The energy's back up and it's looking like a proper repeat of that Wednesday. This long-period swell will be a treat at the point.

The first days of September hold some more size, but winds look a bit more cross-onshore.

Also, just so you know, the water temp at Bawa is about average for the season. Nothing weird there. This spot is a reef and point break, and with these long-period swells, it's going to be breaking with real focus. It's a heavy wave, so it's for the advanced riders. If you're not comfortable, stay clear.

So, mark your calendar for Wednesday morning the 19th, and then keep an eye on that Sunday the 30th. Those are your two best bets. The rest is either too messy, too small, or just plain inconsistent.

Rusty out.

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.
