The Lowdown

Alright, this is Rusty, and I’m looking at the next couple of weeks for Bawa (reef and point). This stretch is a bit of a mixed bag—some real gems, but also some flat spells where you’ll want to sit it out.

The water temperature is about average for this time of year, nothing unusual. The swell is almost all from the SSW to SW, which is exactly what this spot likes.

The real standout starts Thursday, 27 August. Thursday morning the swell is a clean 4.3ft from the SSW with a super long period of 19 seconds—that’s groundswell with serious energy (1870 combined energy). The wind is glassy, calm, and the conditions are excellent for experienced surfers. This is the best session in the whole outlook. Afternoon gets a light onshore breeze, so that morning slot is the one.

Friday, 28 August, the swell jumps to 6.9ft from the SSW, but the wind turns cross-onshore, making it a bit messy. Still, that’s a good size for strong surfers, just not as clean. The energy is high (2164), but the quality drops.

We hit a patch of so-so days from Saturday, 29 August through to Monday, 31 August. The swell stays around 4.3ft to 6.2ft, but the wind is mostly onshore or cross-onshore, with periods of glassy conditions only on Sunday morning. That Sunday morning is interesting: 2.6ft from the SSW, 21-second period, glassy, and excellent conditions for experienced surfers (1008 energy). It’s small but very clean.

Tuesday, 1 September, sees the biggest swell of the period: 7.5ft from the SW, with 17 seconds and a huge 3134 combined energy. That’s strong, powerful wave energy. But the wind is cross-onshore in the morning and onshore in the afternoon, so it won’t be perfect. This is only for experts.

The rest of the first week into early September is a mix of glassy mornings and clean afternoons, but the swell drops to 3.3ft to 4.9ft. On Saturday, 5 September, the morning is glassy again with 3.9ft SSW swell and 12 seconds, but it’s not the best of the run.

The second week, from 6 September onwards, has some promising but less certain windows. Sunday, 6 September, has a glassy morning with 4.3ft SSW swell, 14 seconds, and excellent conditions (1016 energy). The afternoon is clean with a light cross-offshore breeze. That’s a solid day. But from Monday, 7 September, the swell fades to 2.3ft–3.3ft, and the wind is mostly cross-off or light, keeping conditions clean but small. There’s a long gap of only marginal surf from 9 September onwards, with mostly cross-onshore winds and small swell, until the very end of the outlook on 11 September where the swell bumps back to 4.6ft but with cross-shore wind.

Best bet: Thursday morning, 27 August, for the combo of size, long period, and glassy wind. Sunday morning, 30 August, and Sunday, 6 September, are also excellent for clean, smaller waves.

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.
