The Lowdown
Alright folks, Rusty here. Let’s have a look at what Lajinha has got cooking for us over the next couple of weeks.
Honestly, I’m a bit gutted to say this, but the outlook is a tough one. The entire 16-day window is basically one long flat spell of poor surf conditions. There isn’t a single standout session, or even a decent one to point you towards. The swell is weak, the wind is a constant problem, and every single entry in the forecast has that dreaded "poor surf conditions" tag. You’ll be looking at a solid two weeks of groveling or just keeping the board in the car.
The break itself is a consistent reef setup at Lajinha, which normally would be a good thing, but the wind is the killer here. For almost the whole period, we’re stuck with a cross-onshore breeze from the ESE or SE, blowing at 12 to 19 mph. That’s putting a chop and a bump on everything. The swell direction is coming from the east, which is the optimum direction for the break, but the waves are tiny and short-period. Swell heights barely scrape 4 ft, and the period is a dismal 6 to 8 seconds. That’s short-period windswell, not groundswell, so the wave energy is weak – you’re looking at combined energy values mostly in the low hundreds, like 121 (moderate wave energy) on the 14th, and a peak of 305 (moderate wave energy) on the 25th.
The water temp is sitting at a warm 81°F with a 2°F anomaly, so it’s a touch warmer than average for this time of year, but you won’t be spending much time in the water because the waves just aren't there.
There is a brief moment on the 23rd where the wind shifts to a gentle onshore breeze from the ENE, but the swell is still only 3 to 4 ft with a 7-second period – it’s not enough to get excited about. The morning of the 24th also sees a bump in energy to 180, but the cross-onshore chop ruins it.
Later in the window, on the 24th afternoon and the 25th, the period finally stretches out to 11-12 seconds, which hints at a bit more grunt, but the wind is still fresh and cross-onshore at 16-19 mph, making it rough and lumpy. The wave state is described as "moderate cross-shore with a cross-chop" and "fresh cross-onshore and lumpy." It’s not surfable.
Given the persistent cross-onshore wind and the small, choppy conditions, this setup looks more interesting for kite surfing than paddle surfing. The reef is exposed and the wind is just ruining any chance of a clean wave.
I’d keep the board stored away for this one. The forecasts can always shift, but right now, it’s a solid two-week no-go.
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.
