The Lowdown
Alright folks, Rusty here with a look at the upcoming surf for Lajinha. I’ve gotta be straight with you – the next two weeks are looking pretty grim for us. The guidance shows nothing but poor surf conditions all the way through the 28th of August.
The main issue is the wind. It's mostly a moderate cross-shore, cross-offshore, or cross-onshore breeze, which is keeping the ocean choppy and messy. There’s no good swell direction coming from the east or east-southeast, which is not working well for Lajinha’s setup. The optimum swell here comes from the east, but it’s just not delivering any quality. We’re looking at a long blank run with no standout sessions on the horizon.
Looking at the first few days, from Thursday the 13th through to Saturday the 16th, we’ve got waist-to-chest high swell, but the periods are short, between 6 and 8 seconds. The combined swell energy is weak to moderate, reading between 104 and 317, but everything is labeled “poor surf conditions.” The wind is ruining any chance of clean waves. Saturday morning the 15th might be the closest we get to clean, with a cross-offshore wind, but it’s only 3ft of weak, short-period swell – barely worth the paddle.
Things don’t improve much in the second week. We see a bit more energy from the 16th to the 18th, with some swell hitting 5ft, but the wind is fresh and cross-shore or cross-onshore, creating lumpy, choppy conditions. The energy is moderate, around 228 to 317, but again, the quality is zero. By the 25th of August, we see a similar pattern with a fresh cross-shore breeze and lumpy cross-chop. Honestly, this setup looks more interesting for kite surfing than paddle surfing.
To make it worse, Lajinha is a reef break, so without clean conditions and a decent, well-directed swell, it’s just not going to fire. The whole 16-day window is a write-off.
Sorry, folks. There’s just nothing worth grabbing your board for right now. Keep an eye on the charts though – things can change. This is Rusty, signing off.

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.
