The Lowdown
Alright, this is Rusty, and I’m looking at what we’ve got on the horizon for the coming weeks. Honestly, it’s a bit of a tough stretch for the paddle crew at Lajinha, a reef break that’s built for the advanced surfer and is consistent, but the conditions are just not lining up for a good session.
We’re looking at a 16-day window starting now, and the surf is on the small side throughout. The energy from the swell is moderate at best, with the combined energy reading around 254 (moderate) to start, and it stays in the low to mid hundreds for the whole period. The swell direction is coming from the east and east-southeast, which is a bit off from the optimum swell direction for this spot, which is from the east. The swell period is short, around 7 to 8 seconds, so it’s windswell, not the kind of groundswell that gives you that deep, pushy energy.
The water temperature is 81° and the anomaly is just 1°, so that’s about what you’d expect for this time of year—nothing to write home about.
Monday afternoon kicks it off with a 5 ft ESE swell, but the wind is a fresh cross-shore from the southeast at 22 mph, which is just going to chop it up and make it lumpy. That’s a trend that sticks around for days. The wind is a real problem here. It’s mostly cross or cross-onshore, freshening up to moderate and fresh breezes, and that’s going to keep the surface messy and the waves sectiony. For a reef break like Lajinha, you want clean, groomed lines, not a cross-chop.
Through the rest of the week and into the next, the swell height hangs around 4 ft to 5 ft, and the period never gets above 8 seconds. The wind doesn’t let up either—it’s a persistent cross-onshore from the east-southeast or east, with speeds between 9 and 16 mph. The wave comment is consistently “poor surf conditions,” and that’s the story.
There’s really no standout in this forecast. The first few days are a write-off, and the second week doesn’t look any better. The swell is weak, the wind is wrong, and the quality is just not there. If you’re a kiter, the onshore wind and lumpy, small waves might actually be more fun than trying to paddle this mess. But for a surfer, this is a blank run. It’s not unusual for this area to have spells like this, but it’s a bummer.
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.
