The Lowdown
Alright folks, Rusty here. Let's get into it.
We’ve got a solid run of surf coming up at Bahia Santa Cruz, starting Thursday the 20th of August, but it takes a minute to get going. The early morning on Thursday offers a tiny 3ft SSW swell with a period of 14 seconds, but it’s just not enough to get excited about with the combined energy at a weak 345. It’s a real slow start.
The first standout session is going to be Saturday morning, the 22nd of August. The water is a touch warmer than normal for this time of year at 88°, and the conditions are set to be absolutely perfect. We’re looking at a clean 3ft SSW groundswell, with a very long period of 16 seconds, and the wind is dead calm – glassy as. The combined energy is moderate at 580, so while it’s not huge, that long period will give the waves some real shape. This is a great session for intermediates, but keep in mind it’s exposed to the SSW and the crowd factor is "sometimes", so you might have some company. The long period also means the sets will be a bit more spaced out, making it easier to paddle out.
Sunday morning the 23rd and Monday morning the 24th carry on the theme with glassy conditions and clean 2ft SW swell. The period on these is a massive 18 seconds, which is very long, and the energy is still moderate (796 and 571 respectively). These will be cracking, clean waves for the intermediate surfer.
Looking further ahead, we have a promising uptick in size. Friday morning, the 28th of August, sees a 4ft SW groundswell with 16 second periods, and the combined energy jumps to a strong 813 with glassy conditions. This is a real option for the weekend ahead.
Then, keep your eyes on Sunday the 30th of August. The morning brings a 5ft SSW swell with a 15-second period and the combined energy is a strong 1149. The wind is glassy, and the call is for excellent surf conditions for experienced surfers. This is the biggest, cleanest swell of the whole period, a real standout for the more experienced crew. The wave height is tipping into the zone where it’s best for experts.
After that, there’s consistent, clean, glassy mornings through the first week of September, with the 1st and 2nd offering 4ft to 5ft SSW swells and moderate energy. The 4th of September shows a final burst of energy with a 4ft SW swell and an 18-second period, but the afternoon gets chopped out by a strong cross-onshore wind.
Overall, you’ve got a solid two-week window here. The standout is the Sunday the 30th morning for the more experienced, and the Saturday morning the 22nd for the intermediate crew wanting perfect, clean conditions.
Rusty.

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 Bahia Santa Cruz 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.
