Alright, Rusty here again. Let's break down the local surf scene, same deal, just in the good ol' imperial system.
The period kicks off with a decent pulse of long-period SSW groundswell, and this reef and point setup is the perfect spot to handle it. The water temperature is about 84°, which is pretty standard for this time of year, only a touch warmer than normal.
Sunday July 5th is the first real goer. Bawa is seeing a 4ft SSW swell with a 16-second period. Morning wind is a light offshore from the North at 9 mph, keeping the waves clean. The afternoon wind shifts to a cross-offshore from the NNW at 12 mph, which still holds it together.
The next few days, Monday 6th and Tuesday 7th, are a bit of a bust with messy winds. Tuesday morning has a light offshore and a 4ft SW swell, but it's not the best of the run.
From Wednesday July 8th through to Sunday July 12th, the onshore winds take over, making the surf choppy as the swell pushes up to 6ft. The energy gets high, but the ride quality is poor. The afternoon of Sunday 12th goes glassy with a 3ft SSW swell, but it's a tiny, brief reprieve.
Now, the real standout to put in your calendar is Tuesday July 14th. Forget the wind issues on Monday. Tuesday morning serves up a 5ft SSW groundswell with a very long 18-second period. The conditions are glassy with a light Easterly breeze. This is world-class for the experienced surfer. The long period means bigger gaps between sets, making it easier to get out back, and the reef will shape those waves perfectly.
Wednesday July 15th is the call for the experts only. A 6ft SSW swell (17s) with glassy conditions in the morning. That's a lot of power.
The end of the week fades a bit, but Sunday July 19th morning offers a clean, glassy 4ft SSW swell.
And the real late gem is Monday July 20th. The whole day is glassy – zero wind. A 4ft SSW swell isn't the biggest, but with flat-calm conditions, it will be a fun, clean session without the crowds.
The best on offer is without a doubt Tuesday July 14th morning. Wednesday 15th morning is for the big-wave crew. The rest of the forecast is mostly a waiting game or small, quiet sessions.
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.
