The Lowdown
G’day, I’m Rusty. Let’s talk about what’s comin’ for the surf at Alex.
First thing – this is a proper week-plus grind. You’ve got a stretch from now (August 16th) all the way through to the morning of Thursday, August 21st that is just poor – onshore, messy, and not worth paddlin’ for. The water’s sitting at a warm 79°, which is about average for the time of year – nothing wild there.
That Thursday morning, the 21st, finally hands us a glimmer. Swell is a small 4 ft from the ESE with a short period of 8 seconds, and the wind goes glassy – offshore from the NNW at just 3 mph. Wave energy is weak (163), so you’re not gettin’ any punch, but it’ll be clean. Not a standout, just a breath of fresh air after the rubbish.
The real standout, the one you wanna circle, lands on Thursday morning, August 27th. The swell picks up to 4 ft from the SSE with a better period of 8 seconds – still not groundswell territory, but the energy climbs to a moderate 293. More importantly, the wind is a light NE cross-off at 6 mph, giving you clean faces. This is your best bet in the run. Expect good surf conditions. You’ll have a reef break working, exposed to the south, but with this swell direction it’s decently lined up. Crowds are possible here – "sometimes" busy – so get in early.
If you miss that, the next Monday morning, August 31st, also looks promising. Same setup – 4 ft from the ESE, period 8 seconds, clean with a light N cross-off at 6 mph, and energy at 249. Good surf conditions again, but it’s a week and a half out so treat it as a hopeful heads-up.
For the rest – Saturday the 29th and Sunday the 30th – you’ll see wind staying onshore or cross-onshore, swell pushing 5 ft to 5 ft but short period, and surf quality stays poor. Not your days. The last Tuesday, August 26th, has a clean morning but only 4 ft and weak energy (177), so it’s surfable but nothing to get worked up about.
All in all, the 27th is the pick – clean, moderate energy, and that cross-off wind. Everything else is a watch and wait.
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.
