Imperial Version
Alright, crew, Rusty here. We’ve got a solid run of surf coming up at a single spot that’s a real standout for the next couple of weeks. Forget looking around – this is where it’s at. The only break on the radar is Bawa, a very consistent reef and point setup that handles a SW groundswell like a champ. The water temp is sitting at a balmy 86°, which is about normal for this time of year.
The pattern is mostly a long-period SSW groundswell pulse that starts Wednesday morning, July 8th. It’s not a beginner zone; with swell over 6ft right out of the gate, this is for the experienced crew. The waves are already running at 6ft on a 15-second interval from the SSW, and the combined swell energy is pumping at 1288 (moderate energy). The morning has a light NNW cross-offshore breeze, making for some clean, lined-up faces. The afternoon looks more marginal with a cross-shore wind.
Thursday, July 9th, is a bit of a write-off with onshore winds and a risk of thunderstorms. It’s not looking worth the paddle.
Friday morning, July 10th, is where we get a proper glow-up. The swell stays strong at 6ft from the SSW, period bumps to a very long 16 seconds, and the energy climbs to 1591 (moderate to strong). The wind? It goes glassy. That’s about as good as it gets for a morning session – pure, clean potential. Definitely the standout of the first week.
Saturday, July 11th, starts with another glassy morning, though the swell drops a touch to 5ft from the SW. Still a solid wave for the advanced surfer. Sunday and Monday, July 12th and 13th, drop off significantly. The swell dips below 4ft and the wind goes onshore, so the quality fades. It’s a quiet couple of days.
Then Tuesday, July 14th, throws a curveball. The morning looks small at 3ft, but the period is a massive 18 seconds from the SSW, and the energy is back up to 1236 (moderate). That’s a long-period groundswell arriving, which at a point setup like Bawa will create some real, long, grinding lines. The afternoon picks up to 5ft on a 17-second period, with a massive energy spike to 1843 (moderate to strong). The onshore wind is a shame, but the power is undeniable.
The following week sees more of the same solid SSW groundswell. Wednesday, July 15th, through Friday, July 17th, keep the 5ft to 6ft range, with some glassy windows on Thursday and Friday mornings. The real heater, though, is looking like Monday, July 20th, and Tuesday, July 21st. Monday morning shows 6ft from the SSW with a 16-second period and zero wind – totally glassy. The energy is a big 1889 (moderate to strong). Tuesday morning then goes off: 7ft from the SSW on a 17-second period, combined energy at a pumping 2965 (very strong), and a clean cross-offshore breeze. That is the heavyweight punch of this outlook. It’s big, powerful, and clean, but at that size over 8ft, it is strictly for experts only. The confidence is decent given it’s over a week out, but this setup has the hallmarks of a genuine day to circle.
Crowds at Bawa are listed as “sometimes,” so you can expect a few other keen locals out there on these better days, but it’s not going to be a circus. The optimum swell direction is SW, and we’re getting SSW, so it’s slightly off-angle but still firing perfectly on this reef and point.
So, the call is simple: Friday, July 10th morning for the clean, long-period glass, then lock in Monday, July 20th, and Tuesday, July 21st, for the serious power. Don’t sleep on it.
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.
