The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this outlook for Lajinha is a tough one to write. I’ve scanned the charts, and honestly, I’m struggling to find a session that’s worth paddling out for. The whole 16-day window is a bit of a write-off for decent waves.
The overall pattern is dominated by a persistent cross to cross-onshore wind, mostly from the SE and SSE. It’s a real shame because the swell is there, but the wind is just wrecking the surface. The water is sitting at 81° – that’s about average for this time of year, so no worries there.
The first real chance of anything semi-rideable comes on Wednesday, August 12th. The morning session shows a cleaner window with a cross-offshore breeze, but the swell is a weak 5ft from the ESE, with a short period of 7 seconds. The combined energy is moderate (231). The conditions are described as ‘clean’, but the swell quality is just marginal. It’s the only flicker of light in the first week. The afternoon goes straight back to lumpy cross-shore chop.
From Thursday, August 13th right through to the end of the month, I’m picking up zero scores. The wind is either cross or cross-on, and the swell, while present at times, is just too short-period and choppy to do anything with. The swell period rarely gets above 8 seconds, which means it’s just a messy, wind-swell slop.
There’s a spike of energy on Sunday, August 16th morning, with a combined energy of 721 (strong). But the swell is 5ft from the ESE with a period of 12 seconds, and the wind is a cross-on 12 mph. That’s a classic recipe for a close-out disaster – all that energy and nowhere to put it cleanly. The afternoon sees the energy drop right back down.
The second week of the outlook is more of the same dreary pattern. The wind stays in the ESE/SE, the swell stays short and weak. The last day with any real data, Tuesday, August 25th, is still just cross-on chop and short-period swell.
The fact is, Lajinha is a consistent reef break that’s exposed to the east, but it needs a cleaner wind window than what we’re getting. As it stands, with the persistent cross-shore and onshore flow, this setup is looking far more interesting for kite surfing than paddle surfing. It’s a blank run, and for this area, it’s not entirely unusual when the trade winds lock in like this.
Keep your boards waxed, but I wouldn't hold your breath. Check back with me tomorrow.
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.
