The Lowdown
G’day, I’m Rusty. Let me break down what’s coming for the Lajinha area for the next couple of weeks.
Honestly, it’s a pretty bleak outlook for paddle surfing at Lajinha. From Thursday, August 13 all the way through Friday, August 28, the wind is constantly blowing from the south-southeast or southeast at 12 to 19 mph, and it stays either cross or cross-onshore, making the surface lumpy and choppy – no clean, glassy sessions in sight. The swell sits between 3 ft and 5 ft, mostly from the east-southeast to pure east, with periods of only 6 to 8 seconds, so it’s short-period windswell, not the good long-period stuff we’d want. Every single session over the full 16 days is flagged as poor surf conditions.
Lajinha is an exposed reef break that works best when the swell comes from the east, and when it’s right, it can handle some size. The water temp is 81°F, which is about average for this time of year ( 1°F above normal), so that’s fine. But the wind ruins it. The combined wave energy stays low to moderate, the highest being 291 (moderate) on Sunday the 16th when the swell pushes 5-5 ft, but that’s paired with a fresh 19 mph cross-shore wind, so it’s lumpy and messy.
There is no standout window. The wind and chop work against you every day. If you’re really keen, maybe the 16th with 5 ft and cross-shore could be one for the kite gear rather than a surfboard. For Lajinha, a long dry spell like this is not unusual for this season – forecasts can change, but right now there’s nothing to get excited about.
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.
