The Lowdown
Alright, Rusty here, and I’ve got to be straight with you – the next couple of weeks are looking tough for a proper paddle. Let’s talk about Lajinha, a reef break that usually needs a good easterly swell to work, and the direction is right, but everything else is fighting against us.
The water is sitting at 81°F with a tiny anomaly, so it’s feeling normal for the time of year, nice and warm. The problem is the wind. For the entire 16-day window, we’ve got a relentless SE to ESE breeze. It’s nearly always cross or cross-onshore, and that’s just tearing up the wave face. Even when the swell bumps up a little, the fetch is generating a windswell with periods as short as 5 to 8 seconds, so the energy is weak and messy. The combined energy barely cracks three digits, usually hovering around 110 to 239 (moderate), but it’s all chop.
Starting now, Saturday the 15th, we’ve got tiny 2ft to 3ft waves with a short 5 to 10-second period. The wind is a moderate cross-shore, and the surf is rated poor. That sets the tone. Sunday the 16th sees a little push to 5ft in the afternoon, but the period drops to 6 seconds and the wind is a fresh 19 mph cross-shore, creating lumpy, ugly conditions. It’s just not worth a paddle.
Through the rest of the week and into the next, it’s the same story: swell heights bouncing between 3ft and 5ft, periods stuck at 6 to 7 seconds, and the wind staying cross-on or cross. The energy is moderate at best. There’s a long gap of nothing but poor surf.
The standout moment, if you can call it that, would be the very end of the window. On Saturday the 29th morning, we get a rare moment of offshore wind from the ENE at 9 mph, with a 4ft swell from the same direction. The period is still short at 6 seconds, and the energy is weak (105), but it’s the only time the wind is blowing clean. It’s over a week away, so the forecast is uncertain, but that’s the only window where the reef might hold a little shape. Considering the rest of the run, that’s the best we’ve got.
For now, leave the boards in the bag. It’s a blank stretch, and for an exposed spot like Lajinha, that’s not unusual when the trade winds lock in. Keep an eye on that last Saturday morning, but don’t hold your breath.
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.
