The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for Aracaju over the next couple of weeks.
Truth be told, it’s a pretty grim stretch. The guidance tells me the swell direction is off our optimum and the onshore winds are going to be a persistent problem. The whole 16-day run is littered with "poor surf conditions" – nothing but messy, choppy, onshore slop. There’s a real gap here with no good surf on offer, and it’s a long, blank run for the area.
Starting from Monday, 17 August, and right through to the end of the month, we’re stuck with a consistent SE wind. It’s cross-onshore at best, often just straight onshore, and that’s the real killer. The wave energy is weak to moderate, with values like 438 (moderate) on Monday morning dropping to only 69 (weak) late on Sunday, 23 August. The swell is all short-period, mostly 7 to 9 seconds, which is just windswell junk. Wave heights bounce around 3 ft to 6 ft, but with that wind, it’s all chop and no shape. The water temp is 80°, which is a touch warmer than normal for this time of year, but you won’t be feeling the love with that wind in your face.
The only slight flicker of a change comes on the 1st of September. There’s a brief spike in energy on Tuesday morning with a reading of 849 (moderate to strong), and a 6 ft swell from the east. But the wind is still cross-onshore, and the direction is still wrong for us. The afternoon of that same day shows a promising 18-second period from the south, but it’s a tiny 2 ft and the wind is still cross-onshore. It’s not enough to save the week.
To be brutally honest, there’s nothing here worth paddling out for. This is a classic case of a surf-starved spell. The beach setup with persistent onshore wind is more interesting for a kite surfer than a surfer right now. Keep an eye on the forecasts, because this can’t last forever, but for now, take the boards off the roof and enjoy the beach.
Stay tuned,
Rusty

Information about the Aracaju Surf forecast
The above surf forecast table for Aracaju provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Aracaju can be found by selecting the local surf guide option on the grey menu. Our Aracaju 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 (Aracaju) 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 Aracaju 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.
