The Lowdown
G’day, Rusty here. Let’s be straight with you – the outlook for Lajinha over the next 16 days is a tough one. The wave energy is all over the place, and the wind just won’t play nice. The water’s sitting at a warm 81°, which is about normal for this time of year, but that’s where the good news ends.
We kick off on Wednesday the 19th of August with rain showers and a fresh cross-shore wind blowing at 19 mph. Swell is 5 ft from the ESE with a short period of 7 seconds, and the energy is moderate (234). The wind is making a mess of things – lumpy cross-chop. The conditions stay pretty poor across that first week, with the wind swinging between cross and cross-onshore, and the swell hovering around 3 ft to 5 ft. The best you’ll get is a bit of a lull on Saturday the 22nd, but even then the swell is small and the wind is choppy. It’s not looking good for a paddle.
The second week doesn’t offer much relief. By Monday the 24th of August, the swell jumps to 5 ft but the energy spikes to 400 – that’s strong. Still, the cross-onshore wind kills the quality. From the 25th right through to the end of the month, we’re stuck with fresh to moderate cross-shore winds, short-period 4 ft to 5 ft swell, and constant “poor surf conditions” in the notes. Lajinha is a consistent reef break, so it normally has something, but the wind is just relentless.
Looking into early September, the pattern doesn’t change. The swell drops back to around 4 ft to 4 ft, still short-period (6 to 7 seconds), and the wind is either onshore or cross-onshore from the east. The wave energy stays moderate (122 to 177). Honestly, there isn’t a single standout session across the whole 16-day window. The setup looks more interesting for kite surfing than paddle surfing – those cross-shore winds and consistent swell lines are better for a kite.
So, plain and simple: no good surf options here. Lajinha’s a consistent spot, so it’s a bit of a bummer, but a blank run like this happens. Stick tight – forecasts can 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.
