Table - best surf conditions forecast for Prainha over the next 16 days.
Alright folks, Rusty here with a look at what's on the table for the next couple of weeks. We've only got one spot really on the radar, and that's Prainha. It's a consistent, advanced break, so don't expect any easy rides if you're just starting out. The water temp is about average for this time of year, nothing too wild there.
We're going to kick things off on Thursday the 9th with some tiny, clean surf. We're talking 2ft ESE swell, but it's got some good period to it at 11 seconds. Problem is, the wind's a bit scratchy for the morning and it's a total write-off in the afternoon. The energy is really weak (73) so it's not going to be much to write home about.
Friday the 10th is looking a little more promising. Morning glass-off with light offshore wind from the SW, and the swell's only 1ft but the period's bumped up to a very long 14 seconds. That's proper groundswell energy with a moderate kick at 119. Those long lines will love a point or reef setup. It's still small, but it'll be clean and fun for a log.
Saturday the 11th is a no-go with onshore wind and marginal conditions. But then we get a nice little pulse. Sunday the 12th is the first real standout of the forecast. Morning brings a clean 3ft SE swell with a 12-second interval (236 energy), and it stays quality into the afternoon with, get this, glassy conditions. That's insane for a decent sized wave. If you can only paddle out one day this week, Sunday the 12th is your call.
Then, hold onto your boardies for Monday the 13th. The morning is showing a 7ft SSE swell, but the period is short at just 7 seconds. The energy is strong (598), so there's plenty of power for bigger boards, but it might be a bit sloppy and closed out at the beach. That's expert territory for sure. Afternoon drops right off, so get it in the early.
From Tuesday the 14th right through to Thursday the 23rd, it's a pretty grim run. We get a few fleeting moments of clean, glassy mornings with small swell (2ft to 3ft), but the window is small and the energy is on the weak side. You'll mostly be fighting cross-onshore chop or onshores most days. There's a gap of over a week where there's really no solid, all-day recommendation.
The only other flicker of hope comes on Tuesday the 21st and Wednesday the 22nd mornings. Tuesday has a glassy 3ft E swell and Wednesday a clean 3ft E swell, both with short 8-second periods. For the patient local who doesn't mind a small window, those might be your only dawn-hunting options.
Honestly, the main story here is Sunday the 12th and Monday the 13th morning. For the rest, it's a waiting game. Overall energy is low to moderate for the most part, so don't expect the ocean to be pumping. We'll see if the long-range forecasts shift.
Stay wet, stay keen.
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.
