The Lowdown
Right, cobber, Rusty here. Let’s have a look at what’s coming our way for Bawa over the next couple of weeks.
We’ve got a solid run of swell on the horizon, but this first week is a bit of a mixed bag with wind and conditions. The real standout, the one you’d be mad to miss, is shaping up for the first weekend of August. Get your board ready.
The first real action kicks off on the morning of Thursday, 24 July. A south swell of 5 ft (638 energy) rolls in, but it’s a cross-on ESE wind at 6 mph, so it’s not clean. The afternoon goes fully onshore, so we’ll call that one a write-off.
Saturday, 25 July, the morning brings a treat. The swell drops slightly to 5 ft, but the wind goes glassy at 3 mph from the ENE. That’s a major positive, you’ll get clean, smooth lines. The energy is still moderate (742). The afternoon gets messy again with a cross-on.
Sunday, 26 July, there’s a bit of a low point, with swell down to 4 ft, but the afternoon glass-off from the west at 3 mph should give you some fun little rides. The energy is weaker (541).
Monday, 27 July, the morning is glassy, dead calm, with a 3 ft south swell. It’s small, but it’ll be perfectly clean. A good one for a longboard.
Now, later in the week, things get interesting. On Thursday, 30 July, the swell picks up with a long-period south-southwest groundswell (19 seconds, 997 energy) in the morning, glassy conditions. That’s a sign of better things to come. The afternoon jumps to 4 ft with a massive 1120 energy.
The standout of the whole outlook is the period from Friday, 31 July, through to Monday, 3 August. Friday morning, 31 July, we’ve got a 4 ft south-west swell at 17 seconds, glassy, and the energy is pumping at 1170. This is excellent, experienced surfers will be in their element. The afternoon remains glassy (1028 energy). Saturday, 1 August, gets even better: a 5 ft south-southwest swell with a very long 18-second period, glassy, and the energy jumps to 1662. That’s strong. The wind stays clean through the afternoon with a cross-off.
Sunday, 2 August, delivers again: 5 ft of south-southwest groundswell, 16 seconds, with a cross-off wind and even more energy (1444). The afternoon sees a pulse of 4 ft at 19 seconds with a whopping 1770 energy. Monday, 3 August, is the biggest of the run: 6 ft of south-southwest swell, 16 seconds, cross-off, and the energy hits 1963. That’s a very strong, powerful swell. This is the pick of the fortnight for experienced surfers who want clean, lined-up waves. Bawa is a reef and point, so this long-period groundswell will set up beautifully.
The wind goes a bit sideways on Tuesday, 4 August, with a fresh 19 mph cross-shore, making it lumpy. The swell is still 5 ft, but it’s not worth it.
From Wednesday, 5 August, through to Thursday, 7 August, the swell stays up around 5 ft to 6 ft, but the wind is either cross-off and clean or cross-shore and lumpy. There’s a bit of a mixed bag there. On Friday, 7 August, the swell gets to 7 ft, but the wind is a fresh cross-on at 19 mph, which makes it poor. By Saturday, 8 August, it’s back to 7 ft with a light cross-on, so you might get a few if you’re keen.
The water temperature here is about average for the time of year – nothing unusual to report.
So, to sum it up: the first few days are a warm-up, but the real magic is from Friday, 31 July, to Monday, 3 August. That’s where you’ll find the cleanest, most powerful, and most consistent waves. Be there early.
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.
