The Lowdown

Alright folks, Rusty here. Let's have a look at what's cooking at Bawa.

Right off the bat, the water temp is sitting at a warm 30°, which is about a degree warmer than you'd normally expect at this time of year – a nice tropical hug, that. We've got a solid run of SSW groundswells aimed right at this exposed reef and point break, and the optimum direction is SW, so we're in the ballpark.

The first couple of days are a bit of a letdown. Monday the 14th is a write-off with moderate rain and onshore winds messing up a head-high 6ft swell. The energy is strong (1908), but the conditions just aren't there.

Now, Tuesday the 15th? That's when things get interesting. The morning is an absolute gem. The wind goes completely glassy, and we've got a solid 6ft SSW swell at a long 15-second period. The energy is pumping (1628), and the forecast says it's excellent for experienced surfers. This is the standout of the first week – you want to be on it early before the wind shifts around afternoon.

Wednesday and Thursday look messy again with cross-on breezes and that energy dropping off a touch, but hold the line. Friday the 18th morning offers another window of glory. The wind goes glassy again with a 5ft SSW swell, period still a juicy 15 seconds. It's a smaller day, but clean as a whistle and the wave quality for the experienced crew will be top-notch.

Then we hit a rough patch from the 24th to the 25th. The wind is up, the energy is weak, and it's choppy. Not worth paddling out.

The second week shows some real promise, but it's further out so treat it as a heads-up rather than a guarantee. The morning of Saturday the 26th is looking glassy with a 5ft SSW swell and very strong energy (1540). But the real monster is shaping up for Sunday the 27th. We're looking at a 5ft SSW swell in the morning with a period of 21 seconds – that's proper long-period groundswell, meaning deep water energy. The wind is offshore and light, and the afternoon bumps up to a powerful 8ft SSW swell with energy going through the roof (4848). That's expert territory, boys. It'll be breaking big and clean on the point.

Monday the 28th keeps the energy pumping early with another glassy 8ft morning, before it starts to ease off into the next week.

Overall, the absolute best on offer is the glassy morning of Tuesday the 15th for a clean, solid session, and the big, powerful Sunday the 27th for the experienced guys looking for a proper push. Keep an eye on that long-range one.

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.
