The Lowdown

Alright, Rusty here. Let’s look at what’s cooking for Bawa over the next couple weeks.

The first few days are a mixed bag, but there’s good stuff hiding in there. Friday the 28th of August kicks things off with a solid 7ft SSW groundswell, 16-second period, but that SE wind at 6 mph is cross-onshore, putting a few bumps on it. Combined energy is 2164—decent power, but not clean.

Saturday morning the 29th is the real standout. Swell drops to a clean 5ft from the SW, 14-second period, and the wind goes glassy—ENE at 3 mph. That’s the kind of morning you set the alarm for. Combined energy is 914. The reef-and-point setup at Bawa will be running smooth and lined up.

Sunday the 30th morning is another glassy dawn, with a tiny 3ft SSW swell but a very long 21-second period. That’s proper groundswell—long waits, but serious push when it arrives. Energy is 976. For a point break, that’s a patience game with reward.

Monday the 31st picks back up to 6ft SW at 18 seconds, but the wind goes cross-onshore from the ESE at 3 mph. Workable, but not perfect.

Tuesday the 1st of September morning brings a chunky 8ft SW swell at 17 seconds with combined energy of 3167—strong stuff. The wind is cross-onshore from the SE at 3 mph, so there’s a bit of texture. This is big—over 8ft it’s for experts only.

Thursday the 3rd of September morning is glassy again—ESE at 3 mph—with a 5ft SW swell, 15-second period, energy of 980. Another excellent morning.

Into the second week, Sunday the 6th of September morning has a 5ft SSW swell with a clean cross-offshore ENE wind at 6 mph. Energy is 1032. Clean and groomed.

Wednesday the 9th of September afternoon gives us a 4ft SW swell at 17 seconds, cross-offshore NW wind at 9 mph, energy of 1003. Clean and lined up.

The best of the long-range is Thursday the 10th of September. The morning has a 5ft SW swell with cross-offshore NW wind at 6 mph (energy 1111), but the afternoon goes glassy—NE at 3 mph, swell 5ft SW, same 16-second period, energy of 1445. That afternoon will be buttery.

Saturday the 12th of September morning is another glassy one—7ft SSW, 15-second swell, energy of 2033. That’s expert-level size, but glassy on a reef-point means big, clean walls.

Water temp is 86°, about 1° above average—so slightly warm for this time of year, nothing crazy.

Best in the whole run: Saturday the 29th of August morning and Thursday the 10th of September afternoon. Two glassy, powerful sessions you won’t want to miss.

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.
