The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the coming weeks.
Well, I’ll be honest with you – this is a tough one. We’re looking at Lajinha, a consistent reef break that’s exposed to the swell, but the wind is a real problem. The water’s sitting at 81° right now, which is about average for this time of year, so no surprises there.
The pattern is pretty grim. From Tuesday the 18th of August right through to the end of the month, we’ve got a constant stream of cross-shore and cross-onshore winds, mostly from the SE and ESE, blowing at 12 to 19 mph. The swell is hanging around 3 ft to 5 ft from the ESE and E, with a short period of just 6 to 7 seconds. The combined wave energy is moderate, hitting between 83 and 255 (the energy brackets), but the problem is it’s all wind-affected junk. The wind state is described as "fresh cross-onshore and lumpy" or "moderate cross-shore with a cross-chop" – not the kind of stuff that gets you out of bed.
We do have a brief window on Sunday the 30th of August morning where the wind turns straight onshore from the E at 12 mph, and the swell is 4 ft from the E with a period of 7 seconds, and the energy is 168. But honestly, onshore 4 ft short-period waves at a reef break? That’s going to be a messy close-out. There’s no standout day here, no window of clean, offshore conditions. The whole 16-day run is a write-off for paddle surfing.
Because the wind is so strong and the wave quality is poor for a reef, this setup actually looks more interesting for kite surfing than paddle surfing. If you’ve got a kite, you might find something to play with, but for a surfboard, you’re better off waiting for a change in the forecast. There’s a big gap of no good surf from the start until the end of the forecast period.
Stay patient, and don’t force it. The forecasts can change, and this spot normally can turn on. But for now, it’s a 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.
