The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s ahead for the next couple of weeks.
We’ve got a solid, drawn-out run of SSW groundswell on the cards here at Bawa. This is a reef and point setup, very consistent, and it loves a good SW swell, which is exactly what we’re seeing. The water is sitting at 86°, which is about average for this time of year, so no surprises there.
The first real action kicks off on Tuesday afternoon, July 14th. Swell is a clean 5 ft from the SSW with a long 17-second period, packing a strong 1531 units of energy. The wind is a light onshore, so it’s a bit bumpy for a session, but the size and pulse are there. The standout of the whole run is Wednesday morning, July 15th. Absolutely glassy conditions, a slightly bigger 5 ft SSW swell with a 16-second period, and 1354 units of energy. That’s the one to circle—clean, offshore-friendly, and the break is exposed. This is an advanced wave, so it’s not for the faint-hearted.
The next real highlight is a Monday morning, July 20th. We see a jump in size to 6 ft from the SSW, period at 17 seconds, and a massive 1833 units of energy. The wind is light and glassy from the ENE. This is another prime window for experienced surfers. The swell is getting solid, and the conditions are pristine.
Looking further out, Wednesday morning, July 29th, is another beauty. A 6 ft SSW swell with a 16-second period, 1508 units of energy, and glassy conditions. This one is far out, so it’s a promising forecast, but we’ll keep an eye on it.
A couple of things to note: this spot is exposed, so when the swell gets over 5 ft, it’s not for beginners. The long-period groundswell (over 15 seconds) will wrap nicely around the point, creating those long, clean lines. The crowds are a possibility here, so get in early for the best of it.
The run fades out towards the end of the month. On July 27th, we see a small 2 ft to 2 ft swell but with a very long 21-second period. That’s a lot of energy for a small wave, making for a weird, slow, but clean session. It’s a unique day, not a heavy hitter but a nice change of pace.
So, to sum it up: Wednesday morning, July 15th, is your best bet for the coming days. The July 20th Monday morning is the standout for the next week. And if you’re planning ahead, July 29th looks like a ripper.
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.
