The Lowdown
Alright folks, Rusty here. Let's have a look at what's on offer for the coming weeks at Prainha.
Right off the bat, we're looking at a pretty flat and ordinary run. The first week is definitely not going to have you scrambling for your board. The swell is tiny, mostly around 2ft to 3ft, and the period is short, around 8-9 seconds, so there's not much push or shape to get excited about. The combined energy is weak, often in the double digits (87), and a lot of the time the conditions are just poor or very ordinary. It's a bit of a bummer, really.
Things look a little more promising as we move into the second week. The swell does pick up a touch. Saturday morning, the 1st of August, actually shows a bit of promise. You've got a 3ft swell from the east with a period of 7 seconds. The combined energy is moderate at 114, and the wind is glassy, which is a huge positive. That will make for clean, smooth conditions. Keep in mind, it's a beach break setup here, and with that short period, the waves might be a bit crumbly. It's not a standout, but for this forecast window, it's about as good as it gets. The water temp is sitting at 66°F, which is about normal for this time of year.
Later in the week, the 5th of August (Wednesday) morning is another one to keep an eye on. The swell is 3ft from the east with an 8-second period, and the combined energy is 106. But the real kicker is the glassy wind again. Absolutely clean, no wind to mess things up.
For the rest of the period, it's a lot of cross-onshore and onshore winds, with small, weak swell. There's a few windows where the wind goes offshore or glassy, but the swell is just too small to get excited about. You'll be scratching for waves.
Overall, it's a quiet period. The only real standout, if you can call it that, is the Saturday morning, the 1st of August, and Wednesday the 5th of August morning for the glassy conditions and some clean, small waves. Keep your expectations in check; it's a paddle, not a barrel.
Rusty.

Information about the Prainha Surf forecast
The above surf forecast table for Prainha provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Prainha can be found by selecting the local surf guide option on the grey menu. Our Prainha 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 (Prainha) 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 Prainha 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.
Prainha is 14 km (9 miles) from Sao Francisco do Sul. If you plan a holiday in Santa Catarina - Norte, look for hotels and other accommodation in Sao Francisco do Sul. Sao Francisco do Sul has rooms for a wide range of budgets as well as car hire and transport links.
