The Lowdown
Alright folks, Rusty here. Let’s take a proper look at what’s happening at Alex over the next couple of weeks.
It’s a bit of a slow-burn forecast to be honest. The first few days are a write-off, with Thursday the 10th through to Monday the 15th looking pretty grim. The wind is mostly cross or cross-on from the east, and that swell is short-period, messy stuff. The water is sitting at 80°, which is a touch warmer than normal for this time of year – nothing drastic, but you’ll notice it’s a little balmy.
We finally get a sniff of something decent on Saturday the 12th during the morning. The wind swings to the northwest and goes glassy – that’s a major plus. The swell is 4ft from the ESE with a period of 8 seconds, so it’s not a groundswell, but it’s clean. The combined energy is moderate (249). It’s an intermediate-level reef break that’s fairly consistent, and it’s exposed to the south swell. The glassy conditions will make it look pretty tidy, but the short period means it’s not going to have much punch. It’s the best option on offer in that first week, but it’s not a standout.
The real standout, and the one I’d circle on the calendar, is the morning of Thursday the 24th of September. That’s a long way out, so take it with a pinch of salt, but the early signs are tasty. The wind swings to the east-northeast and goes glassy again. The swell is 4ft from the east with a period of 10 seconds – that’s a proper groundswell, and the period is long enough to give it some shape and energy. The combined energy is strong (653). For a reef break like Alex, a longer period swell from the east will wrap in nicely and offer some proper lines. The glassy conditions are a huge bonus. This is the one to aim for if you can. It’s an intermediate-level wave, and with that size, it’s fine for most competent surfers.
The rest of the second week is a mixed bag. The morning of Sunday the 21st sees a north-easterly cross-off breeze and a 4ft east swell, which is clean but weak (253). The morning of Tuesday the 22nd has a similar setup but with a stronger north-northeasterly wind. The morning of Wednesday the 23rd is also clean but weak. Nothing else really jumps out as a must-surf session.
Honestly, this is a classic case of waiting for the right window. The standouts are few. The best is definitely that Thursday the 24th morning session. If that holds, it’ll be worth the wait. The Saturday the 12th morning is a decent warm-up. Overall, it’s a quiet period, but it tends not to stay poor for long around here, and forecasts can change.
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.
