The Lowdown

Alright, I’m looking at the next couple of weeks here at Bawa, and I’ve got a read on it for you.

The main story is a consistent run of solid SSW groundswell, but the first several days are gonna leave you wanting more. From Friday the 21st through the end of the month, we’re looking at waves in the 6 to 7ft range, but the wind is just not playing ball. It’s mostly light cross-onshore or onshore, so it’s staying a bit chopped up and messy. The water’s warm at 86° and nothing out of the ordinary for the season.

Now, the one to really get excited about is Tuesday morning, September 1st. That’s the payoff. We’ve got glassy conditions and a solid 8ft SW groundswell packing a massive punch. That’s big, powerful surf and it’s going to be absolutely clean. This is a reef and point break, which is the perfect setup for this kind of long-period groundswell. It’s going to be wrapping in and offering some proper walls. Heads up though, at this size and with that energy, it’s strictly for the experienced surfers.

Before that big day, there’s a nice little window on Wednesday morning, August 26th. The swell is a smaller 5ft, but the sea is glassy and clean. That’s your best bet in that early stretch if you don’t want to wait.

After the 1st of September, things stay promising. The 2nd and 3rd have more glassy windows with solid 6 to 5ft swells, and the 4th and 5th drop down to smaller, clean 4ft to 3ft waves for a relaxed session.

So here’s the plan: the first week is a write-off for quality, but it builds to a fantastic peak. Circle September 1st for the big, clean groundswell. The glassy mornings after that are also great. The near-term calls are solid, but that long-range standout is the real deal.

Rusty out.

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.
