The Lowdown
Alright, Rusty here. Let me level with you about the stretch ahead at Lajinha. I've looked over the numbers and, honestly, it's a tough read for anyone hoping to get wet with a clean wave.
We've got a solid 16-day window but right off the bat, there's a big, fat gap of nothing good. The first recommendation doesn't come until the 16th of September, and even then, it's a washout. The pattern is all cross-on winds, from the SE, mostly 15 to 19 mph, tearing up what little swell is there. The combined wave energy sits between 109 and 269 (moderate energy), but it's useless with those onshore chops.
The water is sitting at 81°, which is a touch warmer than normal for this time of year. That's a nice touch for the body, but it won't fix the mess on the surface.
For the first week, from the 16th of September through the 22nd, the swell is tiny, maxing out at 5 ft, but with periods barely hitting 7 seconds. That's short-period wind swell, useless for any real shape, and that cross-on wind is relentless. The wave comment on every single entry is "poor surf conditions." It's all moderate or fresh breeze, choppy, lumpy. Don't even bother. The end of the first week, the 23rd, sees the swell period jump to 12 seconds (a real groundswell) and the energy hits 264, but the swell height drops to 2 ft. Groundswell with no height is a tease, and it's still cross-on. Not worth the paddle.
The second week is more of the same. From the 24th of September to the 1st of October, we're looking at swell heights between 2 ft and 4 ft. The swell period mostly sits at a weak 6 to 8 seconds. The winds stay cross-on or onshore, and it's consistently described as "poor surf conditions." There is no standout day. There is no clean window.
Honestly, this setup looks more interesting for a kite surfer than a standard surfer. The consistent onshore wind at moderate to fresh strength (9 to 19 mph) will keep the surface blasted, but at least the kites would have power. For a paddle surfer, this is 16 days of frustration.
Keep the board in the bag, my friend. This run is blank, and for this area, that's just how it goes sometimes. Forecasts can change, but right now, there's nothing to chase.
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.
