The Lowdown

Alright, Rusty here again. Let’s talk in feet and miles an hour for those who think that way.

Bawa’s a reef and point, and it’s got good exposure. The first day or so is flat, but we get into it proper on Friday, August 14th.

Best session of the whole run is that Friday morning. Swell is 6ft from the south, with a 17-second period – that’s long-period groundswell with proper push. Water temp is 30°C, about normal for the time of year. The energy reading is 2198 (moderate to strong). The wind is glassy – dead calm – so it will be absolute perfection. This one is for the experienced crew; a touch heavy for the learners.

Saturday, August 15th, morning is another cracker. 5ft south swell, 14-second interval, and again, glass. Energy is 1673 (moderate). Clean, lined-up waves.

Sunday the 16th holds the clean run with 5ft and glassy conditions. A little smaller but still sweet.

Then the wind turns ugly. From Monday the 17th, it’s cross-onshore or onshore through the week. The swell builds, though. Tuesday the 18th brings a 5ft SSW swell with a very long 21-second period. Energy jumps to 3121 (strong) in the afternoon, but the onshore breeze at 9 mph will have it chopped up.

Midweek, Wednesday and Thursday, the swell hits 8ft – big, expert-only territory. Energy is over 4700 (very strong), but the wind is 12-13 mph onshore. It’s a washing machine. Probably more for the kite surfers than us.

The good stuff returns on Saturday, August 22nd. The swell is 8ft, and the wind goes glassy in the afternoon. Energy is 2710 (strong). That afternoon is the second real standout. Then Sunday the 23rd stays clean with 6ft and glassy winds all day. A nice way to finish the good run.

Everything after that, from Monday the 24th, fades to small and messy with onshore flow. Not worth the effort.

So circle Friday morning, August 14th, and Saturday afternoon, August 22nd. Those are the ones.

Rusty, signing off.

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.
