The Lowdown
Alright, Rusty here. Let’s be straight about it.
To be honest, this whole 16-day window is a write-off for any kind of decent surf session. We’ve got nothing but "poor surf conditions" stamped all the way through from September 6th right up to September 21st. That’s a solid two weeks plus with nothing worth paddling out for.
The only spot on the map here is Lajinha, a consistent advanced reef break that usually needs an east swell to fire. The problem is the wind. It’s locked in from the ESE to SE, blowing cross-on or cross-shore at 9 to 19 mph, which is just chopping everything up. The swell is small, mostly around 3 ft to 5 ft, with some days pushing 5 ft on Friday the 18th, but it’s all short-period windswell – 6 to 8 seconds – so there’s no real power or shape in the water.
Water temp is sitting at about 81°, which is about normal for this time of year.
Even though Lajinha is a consistent spot, the combination of onshore junk wind and weak, messy swell means there’s nothing to get excited about. The combined swell energy barely makes it into the moderate range, hanging around 107 to 292, but it’s all poor quality energy.
If you’re a beginner, the swell never really gets over 5 ft, so it’s not too big, but the chop and cross-wind make it ugly. For the experts, there’s just no clean face to work with. Honestly, this setup looks more interesting for kite surfing than paddle surfing.
So, sorry folks, but this is a blank run. No standouts, no sneaky windows. A long stretch of flat and blown-out spells it out. Forecasts can change, but right now, I’d leave the boards at home.
Rusty.

Information about the Lajinha Surf forecast
The above surf forecast table for Lajinha provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lajinha can be found by selecting the local surf guide option on the grey menu. Our Lajinha 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 (Lajinha) 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 Lajinha 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.
Lajinha is 15 km (9 miles) from Canguaretama. If you plan a holiday in Rio Grande Do Norte, look for hotels and other accommodation in Canguaretama. Canguaretama has rooms for a wide range of budgets as well as car hire and transport links.
