The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the table for the next couple of weeks.
Right off the bat, I gotta be straight with you: this stretch is a tough one. We’re looking at a full 16-day window with nothing that I’d really want to paddle out for. The whole run is just a long gap of poor surf with no real standouts. The only break on the radar is Lajinha, a consistent advanced reef set-up, and it gets a bit of swell pushing in from the east, but the wind just won’t do us any favours. The water temperature is sitting at 81°F, which is about average for this time of year, nothing wild.
Kicking off on Friday, the 28th of August, the swell is 4ft out of the east with a short period of 7 seconds – that’s weak, messy energy. Wind is smacking it from the southeast at 12 mph, cross-onshore, making for choppy, poor conditions. That theme just keeps rolling. Saturday through Sunday, we’ve got similar 4ft to 4ft east swell with a 6-7 second period, and the wind stays cross-onshore from the ESE or SE at 12-16 mph. The surf is just ugly.
Towards the end of the month and into September, the swell bumps up a bit. On Monday, the 31st of August, we see 5ft from the east, period stretches to 8 seconds, and the energy is moderate. But the wind is still cross-onshore from the ESE at 12-16 mph and there’s even a risk of thunderstorms. That’s not a session you want to be in. That kind of size with that wind just turns it into a washing machine.
The first week of September keeps the same story: 4ft to 5ft east swell, periods between 7 and 8 seconds, cross-onshore winds ESE/E/SE at 12-16 mph, and energy stays moderate. Every single reading says “poor surf conditions.” It’s just not happening.
After the 5th of September, the swell drops back. By the 6th and 7th, you’re looking at 3ft to 3ft east swell, energy falls off, and cross-onshore wind still ruins any hope of clean faces. From the 8th into the second week, we see a little pulse of 4ft on the 9th with a bit more energy, but it’s short period (6 seconds) and the wind is on it. On the 10th of September, we get a brief moment of “on” wind from the east at 16 mph, but with only 4ft and 7 second period east swell, it’s not enough to save the day.
Honestly, this is one of those blanks. The area just isn’t lining up. The swell’s coming from the east, which is the optimum direction for Lajinha, but the wind is constantly cross-onshore and the periods are too short to build any real power and shape. For an advanced reef break, you need clean conditions, and we’re not getting any. This setup looks more interesting for kite surfing than paddle surfing, to be honest.
No good surf options in the 16-day window. Forecasts can always change, but right now, it’s a long stretch of nothing.

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.
