The Lowdown

Alright folks, Rusty here. Let’s get into it.

The outlook for Bawa is a slow burn but builds into some serious juice. We’re looking at a solid run of surf, but the first few days are a bit of a write-off for anything clean. The water temp is sitting at 86°, which is about average for the time of year, so no surprises there.

We kick off Friday the 4th with a 4ft SSW swell, but it’s coming in with a cross-on wind, so it’s choppy and messy. Not worth paddling out. The weekend is much the same: Saturday the 5th has a long-period 3ft to 3ft SSW swell at 17 seconds, but the moderate cross-on breeze is ruining it. Sunday the 6th sees the swell bump up to 4ft and the combined energy climbing to 1187 (moderate), but the wind is still messy. We’re in a bit of a dry spell here.

Now, Monday the 7th morning is where it starts to get interesting. The wind drops to glassy, and we’ve got a 4ft SSW groundswell at 15 seconds. The energy is moderate (913), and it’s going to be clean. That’s the first real window. Then Tuesday the 8th is a standout. Morning glass with a 2ft SSW swell, but the period is a whopping 20 seconds. That’s proper groundswell energy – 1031 (moderate) – and it’s glassy. It’s a bit small, but the quality will be there for experienced surfers. The afternoon sees the swell jump to 4ft with an 18-second period, and the energy is up to 1260 (moderate). Glassy again. This is the best of the first week.

The following week, starting Monday the 14th, is where the real power shows up. We’ve got a 6ft SW swell with glassy conditions, and the energy is 1844 (strong). That’s a solid session. Tuesday the 15th is another cracker: 6ft SSW swell, glassy in the morning, and then cross-off in the afternoon. The energy is 1600 (strong). The real standout, though, is Saturday the 12th afternoon. An 8ft SW swell at 19 seconds, with a combined energy of 4969 (very strong), and it’s glassy. That’s a big, clean swell for experts only. It’s a reef and point break, so that long period will wrap in nicely. Crowds are possible here, so keep that in mind.

The second week keeps the quality high. Tuesday the 15th and Wednesday the 16th both have glassy mornings with 5ft to 6ft SSW swells, and the energy stays strong (1309 to 1600). Thursday the 17th brings offshore winds and a 5ft SSW swell at 18 seconds, with energy at 1829 (strong). Very clean.

Overall, the best on offer is the Saturday the 12th afternoon session for the big swell hunters, and Tuesday the 8th for the clean, long-period perfection. The second week is consistently good, but the long-range stuff is promising but less certain.

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.
