Alright, Rusty here. Let’s talk about what’s on offer for the coming weeks at Bawa.
We’ve got a solid stretch of surf ahead, starting this Monday morning, July 6th. The early call is for a clean, long-period SSW groundswell around 3ft, with a 16-second period. That’s proper groundswell energy, and with a light N wind off the land, it’s going to be clean. The water temp is sitting around 86°, which is about average for this time of year. The combined energy is moderate (731), so there’s some push, but it’s not a monster. This is a reef and point set-up, and that long period will mean good, shaped waves with nice gaps between sets. It’s a good pick for a Monday morning session.
Tuesday morning, July 7th, looks even better. The swell picks up to 4ft, still from the SSW, with a 16-second period and glassy conditions under a light NW wind. The energy is building (943), and it’s going to be another clean morning. This is where the week starts to shine.
The real standout, though, looks to be Wednesday morning, July 8th. The swell bumps up to 5ft, still a long-period SSW groundswell (15 seconds), with a light E wind that’s cross-offshore. That’s a clean combo right there. The combined energy jumps into the strong range (1076), so there’s some real power. This is excellent surf for experienced surfers. It’s not too big, but at 5ft, it’s getting up there. If you’re confident, get on it.
Friday morning, July 10th, also has a good look. Another 5ft SSW swell, 16-second period, and glassy conditions with a light SE wind. The energy is even higher (1422). That’s a lot of power, and the clean glassy surface will make for some memorable waves. Again, this is one for the experienced crew.
After that, things get a bit more inconsistent and mixed. The wind becomes more onshore for many of the afternoons, and the quality drops. The mornings from July 11th through to the 18th are mostly marginal, with the swell dropping off and the wind not always playing ball. There are some cross or cross-offshore mornings, but the energy is lower and the conditions are more iffy.
Now, look ahead to Sunday morning, July 19th. That’s a real standout. We’re looking at 6ft of SSW swell, 15-second period, and completely glassy with calm winds. The combined energy is 1540, which is very strong. The forecast is for excellent surf for experienced surfers. That’s a long way out, so it’s a promising one but less certain. If it holds, that’s a day to circle on the calendar.
Monday morning, July 20th, and Tuesday morning, July 21st, also have glassy starts with 5ft and 4ft swells, respectively, but the energy is lower and the periods are shorter. They’ll be worth a look if you’re around, but they’re not the standouts.
So, to wrap it up: the best bets are Wednesday morning, July 8th, and Friday morning, July 10th, with Sunday morning, July 19th, being the long-range one to watch. The crowds are listed as “sometimes,” so keep that in mind.
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.
