The Lowdown
Alright, let’s get into it. The surf’s been a bit of a mixed bag lately, but there’s definitely some juice on the horizon. Right now, we’re looking at a stretch where the swell’s coming up but the wind’s not always playing nice.
Right off the bat, we’ve got a solid SSW groundswell rolling in around 5.2ft with a long 15-second period, but it’s a bit sideshore and the energy is already building, with combined energy at 1788. The water temp is 86.4°, which is about average for this time of year, so it’s warm out there, no worries there. Wednesday morning is clean but the forecast is a little iffy on tide. The afternoon picks up a breeze and the energy jumps to 2103, but it’s not looking great for quality – a bit of a toss-up.
Thursday’s swell bumps up to 6.6ft to 6.9ft, with that long period still holding, making for proper groundswell. The morning looks cleaner, but the afternoon cross-off gets a bit windier. The energy’s strong, like 2909 and 2708. Honestly, we’re still watching the tide.
Friday brings a bit more size, 7.2ft to 7.5ft, and the afternoon has a longer period of 18 seconds, and the energy hits 3570. Still sideshore, but the waves have some push.
Then we get to Saturday. This is where it starts to get interesting. The morning sees a drop in wind to 12 mph from the NNW, going offshore. The swell is a solid 7.5ft, period 16 seconds, and the energy is 2865. The call is “moderate offshore and clean”. This is the first real standout. It’s still big enough for experienced surfers only, but the conditions are shaping up. The afternoon is a bit smaller and the wind goes cross-off, but the morning window is the one.
Sunday is a full glass-off. Both morning and afternoon are glassy, with the morning having a light ESE breeze (3 mph) and the afternoon going dead calm from the west. Swell drops slightly to 6.6ft but with that 15-16 second period, it’s got plenty of power. Energy is still up there at 1916 and 2131. This is your classic clean, glassy day. The water will be like a sheet. If you can get out, this will be the cleanest surf of this stretch.
From Monday, things get a little more complicated. The swell drops a bit on Monday morning (5.9ft) but stays glassy. Then the afternoon sees the period jump to 21 seconds, which is very long. That’s a proper groundswell, but that long period can make beach breaks close out. This spot is reef and point, which is better suited for that kind of swell. The direction swings to the south and it gets cross-on. Tuesday sees the swell jump back up to 6.9ft but with more onshore wind.
Then we get to next Thursday, the 14th. That’s a standout. The swell is projected at 8.2ft from the south, with a 16-second period, and it’s glassy. The energy is strong at 3074, and the call is for excellent surf. That’s the biggest, cleanest swell of the window. It’s a day for experienced surfers only, but it could be firing.
Friday the 15th is still good, with 7.5ft and glass, though slightly less energy. The weekend sees the swell ease off, with Saturday the 16th dropping to 3.6ft, still glassy but smaller. The trough in the middle of the week after that is small, around 3.6-4.3ft, but still rideable if you’re keen.
Now, looking further out, there’s a pulse coming around Tuesday the 18th. The morning is 5.2ft with a 19-second period, but the afternoon is where it’s at – 7.9ft, also with a 19-second period, and the energy is massive at 4958. That’s a strong, strong signal. The winds are light offshore. This is a serious forecast, but it’s a week and a half out, so you know how that goes – promising, but we’ll have to see how it firms up.
The day after, Wednesday the 19th, is looking even bigger, with 9.8ft on the cards. That’s well into expert-only territory, and the winds turn a bit cross. It’s big, powerful, and the energy levels are huge (5555). It’ll be a beast if it comes through, but it’s also a long way out.
So, for the best of the next couple of weeks, I’m looking at two main windows: this coming Sunday, the 9th, for the cleanest, glassiest surf; and then next Thursday, the 14th, for the biggest, most powerful clean swell. The long-range stuff on the 18th and 19th is something to keep an eye on, but it’s too far out to commit to. The spot is Bawa – a reef and point setup that handles this south and southwest swell well. It’s very consistent here, so even if it’s not perfect, there’s always something to grab.

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.
