The Lowdown
G’day, Rusty here. Look, I’ll be straight with you – this 16-day window for Prainha is a tough one. We’ve got a long, bleak stretch of barely surfable days to start, then a flicker of bigger energy later on, but it’s never really gonna fire clean. The water temp’s sitting about average for this time of year, nothing unusual there.
The first real chance to get wet doesn’t come until Monday the 27th of July, and even then it’s a struggle. Monday morning brings a glassy 2ft swell from the ESE, period a short 8 seconds, and combined energy of only 50 (weak). It’s surfable but very ordinary. That’s the best we’ve got for a while. Tuesday the 28th and Wednesday the 29th are similar – Wednesday morning has another glassy 2ft from the E, but it’s still weak, low-energy stuff.
Then we hit a dry spell. From Thursday the 30th through to Tuesday the 4th of August, it’s all poor surf conditions. Wind’s either onshore or cross-onshore, swell drops to 1ft to 2ft, and energy is pathetic – mostly in the teens to fifties. Prainha is an advanced, exposed break, but with nothing to work with, it’s a paddling workout at best. There’s a brief moment Sunday morning the 2nd of August with clean offshore SW wind at 6 mph, but the swell is only 2ft from the E with a period of 6 seconds – barely a ripple.
Things finally start to breathe around Wednesday the 5th of August. Wednesday morning sees a 3ft E swell, period still short at 7 seconds, but combined energy jumps to 117 (moderate). The wind is a clean cross-offshore from the S at 12 mph. It’s still rated poor surf conditions, but that’s the most energy we’ve seen in over a week. Wednesday afternoon gets a bit more interesting: 4ft E swell, period 8 seconds, energy at 207 (moderate). Wind is a cross-shore from the SE at 9 mph, creating a slight cross-chop. It’s marginal, but for a few hours there’s enough to pick off a crumbly close-out if you’re desperate.
Thursday the 6th of August morning is the standout of the whole run. We’ve got a clean 3ft E swell with a moderate offshore WSW wind at 16 mph, energy at 140 (moderate). The water will be clean, and the offshore wind means lined-up shoulders. At 3ft, it’s fine for most surfers, but given the whole two weeks has been flat, this is the pick. Afternoon drops off a bit.
After that, it fades again. Friday the 7th is messy, Saturday the 8th has a clean 3ft E swell with light offshore W wind in the morning, energy at 137 – surfable but nothing special. Sunday the 9th is blown out with 25 mph cross-shore winds, and Monday the 10th sees a clean 2ft leftover.
Honestly, if you’re a paddle surfer, your best bet is Thursday morning the 6th of August. The rest of the two weeks is mostly a write-off. For a break this exposed, it’s been a pretty flat run.
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.
