The Lowdown
Alright, surfers, Rusty here. Let’s break down what’s cooking over the next couple of weeks.
The action starts on Thursday morning, September 10th, with some clean-looking waves. The water temp is about 73°, which is a touch warmer than usual for this time of year—nice for a long session. The pattern kicks off with a decent S swell, but the real standout is a run of quality surf that hits around the middle of next week.
Thursday morning is the first real call. São Conrado is seeing clear skies and a light N wind—that’s offshore for this spot. A solid 4ft swell from the S, with a 12-second period, gives the waves proper shape and energy. The combined energy is moderate (403), and conditions are clean. It’s a damn good start.
The wind swings onshore from the SSW that afternoon, so get out there early. Friday is a mess with messy winds and only marginal surf. Saturday morning looks glassy, but the swell has dropped right off to only 2ft, with weak energy (188). Not much to work with.
Sunday and Monday see the swell bump back up, but the wind is mostly cross-onshore. Monday morning, September 14th, is interesting: a 6ft S swell pumping in, with light NE cross-offshore winds and clean conditions. The combined energy is high (648). This swell is a bit short-period at 8 seconds, so it might be a bit lumpy, but clean winds will make it fun for intermediates.
The real standout stretch starts on Thursday, September 17th. A sweet, long-period S groundswell (13 seconds) rolls in at 5ft, with light ENE cross-offshore winds. The energy is ramping up strong (815). This is shaping up to be the best quality waves of the whole forecast. It carries on through Friday morning, September 18th, with similar conditions and very strong energy (663). If you’ve got a point break or a reef in mind, this longer-period swell will really shine, giving you well-shaped waves and longer waits between sets.
Saturday, September 19th, offers a classic glassy afternoon with a clean 3ft swell and a very long 15-second period. It’s small but clean, and the energy is surprisingly strong for the size (606). That’s a board-changer kind of day.
After that, the swell fades into the third week of September. The week starting September 21st looks poor, with onshore winds and weak little waves. There’s a blink on the morning of September 24th with a glassy 4ft swell, but the period is short (8 seconds), and it’s a one-off before the wind messes it up again.
The Takeaway: Aim for the stretch from the morning of Thursday, September 17th through to the morning of Saturday, September 19th. That’s your window for good, clean, moderate-sized groundswell. The water is slightly warm, so no wetsuit needed.
Rusty, signing off.

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 São Conrado 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.
