The Lowdown
Well, mates, I’ve scoured the charts for Lajinha and, honestly, it’s a tough stretch ahead. This is a consistent reef break that’s exposed, but over the next 16 days, the winds are just not cooperating. We’re looking at a real dry spell, with no standout days on the horizon. The water temp is running about average for this time of year, so at least you won’t be freezing while you’re waiting for a clean wave.
From Thursday the 20th of August right through to Friday the 4th of September, the story is pretty much the same. The swell sticks around, mostly from the east and southeast, with heights ranging from 4 ft to 5 ft. The combined energy fluctuates, with values mostly between 100 and 400, so moderate wave energy overall (237 up to 421). But the wind is the killer. It’s a relentless cross-shore or cross-onshore breeze from the SSE to ESE, blowing at 12 to 19 mph. That’s churning up a lumpy, cross-chop or choppy mess. The swell period is short, mostly 6 to 9 seconds, so there’s no real punch to the waves, just messy, weak lines.
There’s a brief moment on Friday the 21st morning where the swell period hits 9 seconds and the energy bumps up to 388, but the wind is still a moderate cross-shore. It’s a tease, but with the poor surf conditions flagged across the board, it’s not worth paddling out for. The waves are just too chopped up and disorganized.
Honestly, Lajinha is a good reef, but it needs a break in the wind. For the next couple of weeks, your best bet is to stay on the beach, watch the horizon, and hope the forecasts change. It’s a blank run, plain and simple. Nothing here for beginners or experts, just a lot of frustrating, blown-out surf.

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.
