The Lowdown
Alright, Rusty here. Let's have a look at what's cookin' at Alex (reef). Gotta be straight with you—this is a tough stretch. We're lookin' at a 16-day window, and honestly, it's mostly a waiting game.
Right out of the gate, there's not much to write home about. The first real sign of life doesn't show up until Saturday the 12th. The water's sitting at a toasty 80°—a touch warmer than normal for this time of year, which is a pleasant surprise.
The overall pattern is a long, drawn-out run of poor conditions. Most days are plagued by choppy, cross-onshore winds that will leave the surface messy. The combined swell energy is moderate throughout, hoverin' in the mid-100s to low-300s, but with that wind, it's just not worth paddling out. We've got a solid 3-day gap from Tuesday the 8th through Friday the 11th with absolutely no recommendations—just rough, wind-affected junk.
Now, there are two brief windows that stand out. The best of the bunch is Saturday morning, the 12th of September. We've got a small 4ft swell from the ESE with a short 8-second period, but here's the kicker: glassy winds out of the NNW. That'll clean it right up. The combined energy is 241 (moderate). It's a small window, but it's the cleanest surf you're gonna see. For a reef break like Alex, that glassy surface is gold. For an intermediate surfer, this is a solid go. Keep an eye on the crowds, because "sometimes" crowded means you won't be alone if it's good.
Then, looking further out, Thursday the 16th of September has a promising morning. We're seeing a 4ft swell from the E, still a short 8-second period, but the wind turns cross-offshore from the NE. That shifts the energy up to 453 (strong). The data says "clean" conditions. This is the standout for the longer range—definitely worth keeping on your radar, but with a note of caution, as it's over a week away and things can change.
The other brief mention is Saturday the 19th in the morning—another glassy window with 5ft swell, but again, the energy is moderate.
Honestly, for most of this stretch, the setup is blown out, choppy, and cross-onshore. With the beach-and-reef layout and persistent wind, it looks more interesting for kite surfing than paddling in for most of these days.
Stick to Saturday the 12th morning for your best bet. Protect the morning glass.
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.
