The Lowdown
G’day, Rusty here. Let’s be straight with you: the next couple of weeks at Lajinha are looking pretty grim. There’s no good surf on the cards for the entire 16-day window, so if you’re set on getting wet, you might want to look elsewhere. The wind is mostly cross or cross-on, chopping up what little swell we’ve got, so it’s not going to be a pretty picture for paddle surfing.
Looking at the water temp, it’s sitting at 81°, which is right around average for this time of year, so at least you won’t need a thick wetsuit. But the waves... they’re just not there.
The swell stays small all week, between 3ft and 5ft, and the energy is mostly weak to moderate. The combined energy is in the 100 to 200 range most days, which just doesn’t have the push we need. Periods are short too, all 6 or 7 seconds, so even the smaller days will be jumbly and hard to get into.
Monday the 17th has chest-high, short-period swell (5ft at 6 seconds) with a fresh SE cross-shore breeze. It’s going to be lumpy and messy. Not worth your time.
Tuesday the 18th drops to 4ft, but the wind is still cross-on and choppy. Same story for Wednesday and Thursday – more of the same, with rain showers on Wednesday and Thursday just to add a bit of dampness to the misery. Friday is a bit less windy, but still cross-shore and messy.
The weekend isn’t any better. Saturday the 22nd is the smallest of the bunch, with less than 3ft waves and a gentle cross-onshore breeze. It’s almost flat, and the little waves that do roll through will be chopped up. Sunday shows a slight bump to 4ft but the wind stays on it.
And that’s the pattern – bumpy, short-period, messy surf with cross-shore winds all the way through. It’s one of those frustrating stretches where the swell seems to be there, but the conditions are stopping it from ever cleaning up. If you’re a kitesurfer, this setup might actually be more interesting – there’s definitely some wind and lumpy water to play with. For us paddle surfers, it’s a write-off.
The outlook isn’t great for the second week either. The swell energy stays moderate at best, the period doesn’t get above 7 seconds, and the wind does the same thing. There’s a slight chance of a cleaner window on the 29th and 30th with a touch more east in the wind, but it’s still cross-on and messy. It’s a long, flat, bumpy run, and there’s no standout day on the horizon.
Keep the board in the car, but honestly, you might be better off finding a sheltered spot or just giving the ocean a miss for a couple of weeks.
Catch you next time.

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.
