The Lowdown
Alright, Rusty here. Let’s break down what’s happening at Bawa over the next couple of weeks. This is a reef and point break that loves a good SW swell, but we’ve got a slow start before some real gems pop up.
The early days are pretty quiet. Sunday the 6th kicks off with a weak 4ft SSW swell and a moderate onshore breeze—not worth wetting a wetsuit for. Monday the 7th through Wednesday the 9th are all marginal, with small swells between 2ft and 5ft, mostly cross-on winds, and stormy skies. The energy is moderate but the conditions are rough, so sit tight.
Now for the good stuff. Thursday morning the 10th is our first real highlight. Clean 5ft SSW groundswell with a 16-second period and glassy conditions—wind is almost dead calm from the east at just 3 mph. The water is a warm 87°, which is a touch warmer than usual for this time of year. That morning session is going to be clean and lined up for experienced surfers.
Friday the 11th is a write-off with onshore winds and building swell but poor quality. Then comes Saturday the 12th. The morning starts glassy with a 4ft SW swell and a very long 20-second period—energy is strong (2005). Then the afternoon really cranks: 6ft SW swell, still glassy, with combined energy at 3301. This is the best of the whole run. That point will be running smooth and powerful, though with such long period, it’ll be best on the reef or point. Expect crowds—this spot can get busy, and on a day like that, it’ll be packed.
Sunday the 13th still looks solid, with 7ft SW swell and glassy afternoon conditions. That’s expert territory, but if you’re up for it, the energy is very strong (2892) and the wind is off the water.
The second week drops off. Monday the 14th through Saturday the 19th is mostly marginal with onshore or cross-on winds and swell between 5ft and 7ft. Nothing special. But circle Sunday the 20th—glass again, with a 6ft SSW swell. Then Monday the 21st has offshore winds from the north with a 6ft SSW swell. Clean and fun.
Best bet: Saturday the 12th afternoon. Thursday the 10th morning and Sunday the 20th are also worth a look. The rest is either small and messy or too big with bad wind. Get after 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.
