The Lowdown
Alright folks, Rusty here. Let’s get into it. I’ve got the dope on a single spot, Lajinha, and I gotta be straight with you—it’s a tough outlook. We’re looking at a full 16-day window, but the surf gods aren’t smiling on this place. The first real chance for a wave doesn’t come until Wednesday, August 12th, and from there it’s a grim march of poor conditions.
The issue is the wind. For the entire run, it’s hammering in from the south and southeast, blowing cross-shore or cross-onshore. That’s killing any chance of a clean face. The swell is small to moderate, ranging from 3 ft to 5 ft, but it’s all short-period, wind-driven junk with periods of 6 to 8 seconds. The combined swell energy is mostly weak to moderate, hitting a peak of 354 (moderate energy) on the morning of Thursday, August 13th. That’s the biggest pulse of the whole period, but it’s accompanied by a 16 mph cross-shore wind that’ll chop it up.
The water temperature is sitting at 81°F, which is about normal for the time of year, so no worries there.
For the first week, from August 12th through the 18th, every single session is tagged as “poor surf conditions.” The wind is just too strong and from the wrong angle to make anything of the 3 ft to 5 ft swell. The best you can hope for is a lumpy, cross-chop mess. It’s not worth paddling out for.
After the 18th, it doesn’t get any better. The wind dies down a little from the 20th onward, dropping to 9-12 mph, but it’s still onshore or cross-onshore. The swell drops off too, mostly between 3 ft and 4 ft, and the energy is weak, with readings in the 70s and 80s. The whole thing just fizzles out.
There are no standouts here. This is a blank run. For a reef break like Lajinha, which is consistent and exposed to the east, it’s pretty unusual to have such a long stretch of nothing. But the wind is just relentless. Honestly, with the consistent cross-onshore wind and the small, weak swell, this setup looks more interesting for kite surfing than paddle surfing. Don’t bother waxing the board for this one.
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.
