The Lowdown
Right. Rusty here again. Situation at Lajinha: there’s no surf worth paddling for over the next 16 days.
From Saturday the 15th of August right through to the end of the month, the same story keeps repeating. Cross-shore and cross-onshore winds from the SE and ESE between 12 and 19 mph stir up a constant chop. Swell comes from the E and ESE, riding on a short period of 5 to 7 seconds most days. Not enough push, and never clean.
Saturday the 15th sees a knee-high 2 to 3 ft easterly swell, but a 12 mph cross-wind ruins it. The period drops to 5 seconds in the afternoon. By Sunday, the swell bumps up to 5 to 5 ft (1.4m to 1.6m), but 19 mph cross-winds and a 6-second period create lumpy, messy lines. The rest of the week follows suit—waves around 3 to 5 ft, but always chopped by moderate to fresh winds.
The combined energy reading stays weak to moderate through the whole run, rarely hitting the 200s, meaning the ocean just can’t find its rhythm. Rain showers pop up on the 26th and 28th, adding another layer of grim. The water is 81°F, about 1°F warmer than the long-term average—nothing wild, just a touch warm for the season.
There’s nothing here for a surfer. Kite surfers might get a laugh from the consistent side-shore wind and small waves, but for paddle surfing, it’s a bust. It’s a long dry spell for Lajinha. Maybe the next forecast will bring a change.
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.
