The Lowdown
Alright, Rusty here. Let’s talk about what’s cooking at Bawa.
We’ve got a solid run of surf on the way, but it kicks off with a bit of a slow start. Thursday morning (23rd July) is a write-off with messy cross-shore wind and weak, marginal 3ft swell from the SSW. The afternoon is even worse, onshore and sloppy. Don’t bother paddling out.
Friday morning (24th July) is where it starts to get interesting. Clean conditions with a light cross-offshore breeze from the ENE, and a clean 6ft swell from the S, period 11 seconds. The combined energy is moderate at 722 – that’s a proper wave. The wind is light, and the break is a reef and point setup, so it’s going to hold that S swell well. This is a very good option for the advanced crew. Crowds are possible here, so get in early.
Saturday (25th July) is a beauty. Glassy conditions all day, both morning and afternoon, with a clean 5ft swell from the SSE, period 10 seconds. Combined energy is solid at 686. This is clean, fun surf, not too big, and the glassy conditions mean you’ll be surfing perfect lines. This is a standout.
Sunday (26th July) morning sees no wind at all – dead glassy – with 4ft SSE swell. The afternoon picks up a little cross wind, but still very surfable. Monday (27th July) is similar, glassy morning with 4ft swell, but a risk of thunderstorms.
Now, Tuesday (28th July) morning is a treat. Only 3ft of swell, but it’s a long-period groundswell from the SSW, 16 seconds, with glassy conditions. The energy is 620 – that’s a lot of push for the size. This is prime for a point break like Bawa, giving you long, lined-up waves. The afternoon and Wednesday (29th July) continue with clean, glassy conditions and 2-3ft of that same long-period SSW groundswell. Wednesday afternoon looks particularly good with energy jumping to 717.
Things get serious from 31st July onwards. Friday morning (31st July) is glassy with 4ft SSW swell, 17-second period, and huge energy (1011). This is excellent for experienced surfers.
But the real standout is Saturday, 1st August. Glassy morning, 5ft SSW swell, 17-second period, and energy of 1274. The afternoon is clean with a cross-offshore wind and 5ft of the same SW groundswell, energy 1275. This is the best on offer. Long, powerful, clean lines. Sunday (2nd August) and Monday (3rd August) hold similar quality: clean cross-offshore winds, 5-5ft SSW swell, and energy climbing to 1632. Monday afternoon sees a massive jump to 2665 in energy, with a 19-second period. That’s a huge, powerful groundswell. Only for experts.
The week of 4th August stays chunky. Tuesday (4th August) morning is clean with 7ft SSW swell, 17 seconds, energy 2355. That’s big, powerful, and only for the very experienced. The wind stays cross-offshore through the rest of the week, with swell holding around 5-6ft. The energy remains high, but the wind picks up a bit on Wednesday and Thursday afternoons, making it less than perfect. Friday (7th August) morning sees a shift to cross-shore wind and a bit of chop, so the run is winding down.
Overall, the best days are Saturday 25th July for fun, clean waves, and the stretch from Saturday 1st August through Monday 3rd August for the biggest, most powerful groundswell. That’s the one to circle on your calendar.
Rusty.

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.
