The Lowdown
G’day, Rusty here.
Honestly, mate, this is a tough one to call. Looking at the whole 16-day window for Lajinha, we’ve got a blank run stretching from now, September 13th, all the way through to the end of the period on September 28th. That’s a solid two weeks with nothing worth paddling out for. Every single forecast point comes back as “poor surf conditions,” and the scores reflect that. So let’s just walk through what’s actually happening.
From Sunday the 13th, we’re looking at a moderate cross-shore breeze out of the southeast at 16 mph, with a weak little 4 ft swell rolling in from the ESE at a short period of just 8 seconds. The combined swell energy is weak (198). The water’s warm, sitting at 81°, which is about 2° warmer than average for this time of year – a little notable but nothing too wild. It’s choppy, messy, and just not surfable.
That pattern just drags on. Monday the 14th and Tuesday the 15th are the same story: cross and cross-on winds, small windswell, short periods. Nothing cleans up.
We get into the second week, and there’s a slight bump in swell energy around Friday the 18th and Saturday the 19th, with the combined energy climbing into the moderate range (193 to 205). But the swell’s still small, around 4 ft to 5 ft, from the east, with short periods. The wind stays cross-onshore out of the southeast at 16 to 19 mph, so it’s lumpy and choppy.
Late in the period, around Wednesday the 23rd and Thursday the 24th, we finally see the period stretch out to 10 seconds, which is a bit more groundswell-like, and the combined energy spikes to 395 on Wednesday afternoon. But it’s still cross-onshore, the swell drops to 2 ft by Thursday, and the wave comment remains “poor surf conditions.” Too small, too messy.
For a reef break that’s consistent and exposed, this is a real bummer. Usually, you’d think the waves would show up, but this stretch looks like a complete write-off. If you’re desperate, you might look at it for a kite session, because the wind is consistent, but for a paddle surf, there’s nothing.
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.
