The Lowdown
G’day, Rusty here, and I’ve got a straight-up honest look at what’s coming for Lajinha. This is a reef break that’s built for advanced crew, and it’s consistent, which is a good start. But I won’t sugarcoat it – the next two weeks are a real struggle. The forecast is a long, flat run of poor surf conditions with no standouts at all. From Saturday the 29th of August through to Sunday the 13th of September, every session is a write-off. The swell is always small, the wind is cross-onshore from the SE or ESE most of the time, and the wave energy is weak. The water temperature is sitting at 80°F at the start, which is about average for the time of year.
The swell comes from the east, but it’s tiny – never bigger than 6 ft, and most of the time it’s 3 ft to 4 ft, with a short period of 6 to 8 seconds. That’s not the kind of groundswell that gets a reef like Lajinha firing. The combined energy is weak, with values like 167, 127, 160 – all well under 1000, so it’s just a bit of bump, not proper surf. The wind is always cross-onshore, making it choppy and messy. There’s no glassy or offshore wind in sight. Even when the wind shifts to onshore on a few days in early September, it’s still a gentle breeze and the swell is too small to do anything with.
The only slight uptick comes on Monday the 31st of August with a 6 ft east swell and a period of 8 seconds, and the energy jumps to 421, which is still only moderate. But the wind is cross-onshore from the ESE at 16 mph, so it’s choppy and the surf quality is still poor. That’s not a day to get excited about – it’s just a bit more bump in the same dirty conditions. For a reef break that’s best with an optimum swell from the east, the direction is right, but the size, period, and wind are all wrong.
The bottom line is there’s nothing here for the paddle surfer. The setup is more interesting for kite surfing than paddle surfing, given the constant cross-onshore wind and small, choppy waves. It’s a blank run, and for an area like this, that’s normal. Forecasts can change, but right now, don’t bother.
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.
