The Lowdown

Alright, surfers, Rusty here. Let’s look at what’s cooking for the next couple of weeks.

Right off the bat, we’ve got a decent swell train coming, but it’s not all clean. Saturday the 1st has a solid 5ft SW groundswell with a long 17-second period, but the wind is chewing it up with a cross-onshore breeze, making it choppy. The water’s sitting at 86°, which is about average for this time of year, so that’s fine.

The real standout arrives Sunday the 2nd. The morning session is looking prime with a 5ft SSW swell, 16 seconds, and the wind is glassy. That’s a major positive—clean, smooth conditions. The combined energy of all swells is moderate but solid at (1361). It’s a bit of a smaller day, but with that glass, it’s going to be a joy. The afternoon holds a 3ft, 18-second groundswell, also glassy, so you can get a session in after the storms pass.

Monday the 3rd through Friday the 7th, the swell picks up steadily, getting into the 5ft to 8ft range, but the wind is mostly cross-off or onshore, and the forecast is marginal. The energy jumps into the thousands (2024 on the 5th), meaning there’s plenty of power, but the quality isn’t there for the average punter. By Thursday the 6th and Friday the 7th, the swell is over 7ft and up to 8ft with a 19-second period—that’s a very long period groundswell. This is expert territory. The wind is a strong breeze, so it’s going to be a beast. At Bawa, a reef and point, that long period should line up nicely, but it’s only for the brave.

The absolute standout for the whole period is Tuesday the 11th and Wednesday the 12th. Tuesday morning shows a 8ft S swell, 19 seconds—that’s a proper groundswell with massive energy (4963). The wind is glassy, dead calm. Tuesday afternoon is even better on paper: 8ft, 18 seconds, and still glassy, with energy over 5000 (5134). That’s a strong to very strong wave energy. This is the pick of the bunch, but it’s over 8ft, so it’s strictly for experts. Wednesday morning holds onto that energy with a 8ft, 16-second swell and glassy conditions, still excellent.

After that, the swell drops off. Thursday the 13th and Friday the 14th see smaller, weaker swells, and the wind turns onshore again. Saturday the 15th and Sunday the 16th have a 7ft swell, but the wind is onshore, making it messy. The energy is still moderate (2153), but the quality is poor. If you’re not an expert, the best bet is the glassy, quieter days early on, like Sunday the 2nd.

Stay safe, watch the tides, and don’t be a hero on those 8ft-plus days unless you’ve got the skills.

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.
