The Lowdown
Alright, Rusty here again. Let’s talk feet, miles per hour, and Fahrenheit for those of you who think in imperial.
It’s a rough stretch ahead, with only a couple of real chances to get a decent wave. The water’s running at about 80°F, which feels a little warmer than usual for this time of year – not a bad thing.
Here’s the skinny.
First few days are a bust. From Friday, September 11 through Sunday, September 13, the wind is all wrong – cross, cross-on – and the swell is small and choppy. Wave energy is middling, between 175 and 282 on the scale. Not worth the paddle.
Monday September 14 and Tuesday September 15 are more of the same: cross-shore winds, lumpy, short-period 8-second ESE swell around 4 to 4 feet. Just no.
The one bright spot in the first week is Saturday morning, September 12 at Alex. Glassy conditions with a light offshore wind from the NNW at just 3 mph. Swell is 4 feet from the ESE, period 8 seconds, and the energy reading is 245 – moderate but clean. That morning will be your only clean shot for a while. It’s a reef, so the ESE swell will wrap in. Crowds can be around – “sometimes” – but it’ll be worth it. Afternoon goes choppy again.
Then it’s a long, dry gap. From midday Saturday through Wednesday September 16, everything is poor – chop, lumps, cross-onshore.
Wednesday September 16 morning gives a bit of hope: cross-off breeze and combined energy of 403 from an E swell, but the waves are only 4 feet and period is 8 seconds. Tides might mess with it, so it’s a maybe.
The next real standout is Wednesday morning, September 23. Light NNE breeze at 6 mph, cross-off, clean. Swell is 4 feet from the E with a 7-second period, and the energy reading is 305 – moderate but punchy. The offshore wind will make it smooth. It’s not the reef’s ideal direction (they want S), but it’ll be rideable and clean. Crowds possible, so get in early.
After that, it’s all cross-onshore and choppy through the end of September.
So: you’ve got two windows – Saturday morning, September 12 for glassy, and Wednesday morning, September 23 for clean, moderate energy. The rest? Leave the board in the car.
Rusty.

Information about the Alex Surf forecast
The above surf forecast table for Alex provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Alex can be found by selecting the local surf guide option on the grey menu. Our Alex 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 (Alex) 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 Alex 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.
Alex is 6 km (4 miles) from the city of Salvador. If you plan a holiday in Bahia - Norte, look for hotels and other accommodation in Salvador. Salvador has rooms for a wide range of budgets as well as car hire and transport links.
