The Lowdown
Alright folks, Rusty here. Let's get into it for Lajinha.
Right off the bat, this is a tough outlook. The entire 16-day window is a write-off for quality surf. There are no recommendations at all. The swell windows are open, but we’re stuck with a persistent wind pattern that just won’t let up. The combined wave energy sits in the moderate range (between 100 and 283) throughout, so there’s energy in the water, but it’s all cross-shore or cross-onshore wind messing it up. For a reef break that loves offshore from the East, this is a painful run.
From Sunday the 16th through the weekend of the 23rd, it’s a constant theme of choppy, lumpy conditions. Winds from the SSE and SE, blowing 12 to 19 mph, are just shredding the surface. Swell heights bounce between 2ft and 5ft, but it’s all short-period windswell (6-7 seconds), which just means bumpy, weak lines. You’re looking at a solid week-plus of poor surf conditions.
As we roll into the last week of August and the start of September, the swell actually starts to build a bit. By the 28th and 29th, we see swell heights hitting 5ft and the combined energy climbing into the 260-283 range, which is the most powerful we’ll see. The period on that swell stretches to 8 seconds, so it’s a touch perkier, with a bit more push behind it. But here’s the killer – the wind is still coming from the East, and it’s cross-onshore for those days. The water is about 81°F, which is a normal 1°F anomaly for this time of year, so at least the water feels fine.
Then finally, on Sunday the 30th of August, we get a glimmer. The wind shifts to true onshore from the East, but it’s a light breeze at 9 mph in the afternoon. For the first time in the whole forecast, the conditions aren't being trashed by a strong breeze. The swell is 4ft from the East at 8 seconds. It’s the cleanest window in the whole period, but the swell direction is dead onshore, which for a reef is just going to make it dumpy.
Honestly, for a surfer, this is a two-week break. It’s one of those periods where the setup is more interesting for someone with a kite than a paddle. Don’t hold your breath. Forecasts can change, but right now, there’s nothing to get excited about.

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.
