The Lowdown

Alright, let’s break down what’s coming up at Bawa. It’s a reef and point set-up, exposed to the SW, and it breaks very consistently, so we’re not looking at a lot of flat days. The next couple of weeks have a mix of so-so sessions and some real standout windows, but you’ve got to time it right. Water temp is about average for this time of year, nothing unusual.

We start on Tuesday the 25th of August with a bit of a rough entry. Morning shows a 1.8m swell from the SSW, period at 15 seconds – that’s a nice long groundswell – but the wind is cross-on from the SSE at 10 km/h, putting some bumps on it. Combined energy is strong at 1481, but the surface is messy. Afternoon stays onshore, same size, not great.

Wednesday the 26th is where it gets interesting. Morning brings a 1.6m SSW swell, 13-second period, and the wind goes NW at just 5 km/h – glassy, man. That’s the kind of morning where the reef just lines up perfect. Combined energy is moderate-high at 1021. This is a standout for the near term. The break loves SW swell, and we’re close enough. Afternoon turns cross-on and cloudy, dropping to 1.4m, not worth it.

Thursday the 27th, morning is pure glass again – 1.3m, SSW, but the period jumps to a very long 19 seconds. Combined energy is 1870. That’s a powerful groundswell, and with zero wind, the point will be clean and the sets will have some real punch. Afternoon goes onshore, but that morning is a standout.

Friday the 28th, the swell builds to 2.1m in the morning, SSW, 16-second period, but the wind is cross from the ESE at 10 km/h. Combined energy is strong at 2179. The size is getting into expert territory – over 2.5m soon, but 2.1m is solid for advanced surfers. The cross wind might put a little texture on it. Afternoon drops slightly to 2.0m with onshore S wind, so morning’s the better call.

Saturday the 29th, we’re back to smaller, 1.5m in the morning, cross-on wind, nothing special.

Sunday the 30th, morning is a sleeper. Only 0.8m, but the period is a massive 21 seconds – very long groundswell. Glassy conditions from the ESE at 5 km/h, and combined energy at 1014. Don’t let the size fool you; those long-period lines will bend around the point with real shape. This is a standout for anyone who knows how to work a small but clean point.

Monday the 31st, we’re back to 1.8m from the SW, 18-second period, but onshore winds ruin it.

Into September now, and the first week has some real highlights. Tuesday the 1st sees 2.2m SW swell, 17-second period, combined energy at 2873 – that’s strong energy. The wind is cross-on, but the size and period are legit. This is not for beginners; it’s expert territory. Wednesday the 2nd is a beauty – morning and afternoon both glassy with NE or WSW wind at 5 km/h, 1.9m and 1.7m SW swell, 16-second period. Combined energy at 1839 and 1571. These are clean, powerful sessions for experienced surfers. Thursday the 3rd keeps the run going – glassy morning, 1.6m SW, 14-second period, and afternoon goes cross-off from the NW at 10 km/h, still clean. Friday the 4th is another glassy morning, 1.7m SSW, 13-second period, energy at 1030. The consistency of these quality windows in the first week of September is impressive.

The second week fades. Saturday the 5th morning is small and glassy at 1.0m, but the period drops to 13 seconds. Sunday the 6th and Monday the 7th bring 1-1.4m swells with cross or onshore winds, nothing exciting. By Tuesday the 8th and Wednesday the 9th, the energy drops way down – 0.8m on the 9th morning, glassy again but tiny.

Overall, the best on offer is between Wednesday the 26th morning’s glassy 1.6m, and Sunday the 30th morning’s tiny but super-long-period glassy session. For size and power, the first few days of September are also standouts for the advanced crew. Crowds at Bawa are sometimes around, so you might have it to yourself or share with a few mates – that’s part of the deal.

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.
