The Lowdown
G’day, Rusty here, and I’ve just finished reading the charts for Bawa. This is a reef and point break that’s very consistent, and it’s exposed to the SW swell. The water temperature is 86°F with an anomaly of 2°F, so it’s about average for this time of year.
We’ve got a solid run of swell coming, but the first day, Sunday the 19th, is a bit of a write-off. The swell is only 4ft out of the SW at 13 seconds, and with a cross-shore breeze, it’s messy. The combined energy is weak (460), so I’d skip it. The real action kicks off Monday morning.
Monday, July 20th is the standout of the whole outlook. We’re looking at a clean 6ft swell from the SSW with a long 17-second period (groundswell) and a light offshore wind from the NNW. The combined energy is strong (1790), and this is for experienced surfers. The afternoon holds up too, with 6ft SSW swell at 16 seconds and a cross-offshore breeze. This is the best on offer—clean, powerful, and lined up.
Tuesday the 21st still has size, with 5ft SSW swell, but the morning breeze is cross-shore, so it’s a bit lumpy. The afternoon is where it’s at: glassy conditions with 5ft SSW swell at 14 seconds. The combined energy is moderate (1104), and it’ll be clean for a good session.
Wednesday the 22nd morning is glassy but the swell drops to 4ft from the SSW at 13 seconds. The energy is moderate (548), and while it’s a fun size, it’s not the big stuff. Thursday the 23rd drops further to 3ft, and the wind is poor, so it’s a skip.
Friday the 24th sees a pulse of 5ft S swell at 10 seconds, but the wind is cross-shore, so it’s not clean. The energy is moderate (640), but it’s a bit messy. Saturday the 25th morning is glassy with 4ft SSE swell at 10 seconds—good for a clean, mellow session.
Now, Sunday the 26th is a mixed bag. The morning is glassy with 4ft SSE swell at 10 seconds, but the afternoon turns cross-onshore and drops to 3ft. Monday the 27th has a tiny 2ft SSW swell with a very long 16-second period, and a light offshore wind—clean but small. The energy is weak (471).
We then hit a quiet patch. Tuesday the 28th through Wednesday the 30th has small 3ft swell from the SSW, but the winds are all over the place. Some glassy mornings, but nothing to write home about.
Friday, July 31st is another big one. The morning is glassy, with a 4ft SW swell at a very long 17 seconds. The combined energy jumps to strong (1101), and it’s clean. This is a top pick for the long-range—groundswell, offshore, and quality. The afternoon has 5ft SW swell, but the wind is cross-shore, so the morning is the call.
Saturday, August 1st is the second standout. The morning is flat calm (0 mph wind) and glassy, with a 6ft SSW swell at 16 seconds. The combined energy is very strong (1973), and it’s for experienced surfers. The afternoon holds 5ft with a cross-offshore breeze. This is a big, clean swell.
Sunday, August 2nd has size (5-6ft) but the wind is up to 19 mph from the NW, making it choppy. The energy is still strong (1451-1483), but it’s blown out—more of a kite-surfing kind of day. Monday, August 3rd finishes the run with a glassy morning, 5ft SSW swell at 14 seconds, and strong energy (1186). Clean, but not as big.
Don’t bother with the first week’s weak days. The best on offer is Monday July 20th and Saturday August 1st—both are clean, powerful, and for experienced surfers. The long-period swells will be best at the point, not the beach.
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.
