Updates in hr min s Forecast update imminent
Right then, let's have a look at what's on offer. We're in for a bit of a quiet spell here at Prainha, but it’s not all bad news. The water's feeling about average for this time of year, nothing out of the ordinary.
Alright, we start off on July 6th with hardly a ripple – just small, weak swell and messy wind, so don't bother paddling out. That carries on for a couple of days, honestly, you're looking at a bit of a gap here with nothing worthwhile until the 7th. Tuesday morning the 7th brings a jump in energy, with a 5ft SSE swell. It's got a period of 10 seconds and the combined energy is sitting at 645 (moderate). The wind is cross-offshore, which will keep it clean, but the forecast is only marginal. Still, it's the first real chance of a wave.
Wednesday morning the 8th is a small one, 2ft from the ESE with glassy, clean conditions thanks to a light offshore wind, but the energy is weak (122). It's surfable but nothing to write home about.
The pattern stays pretty ordinary until we hit July 11th. Saturday morning the 11th is where things get interesting. The swell is only 3ft from the ESE, but it's got a nice long period of 13 seconds, giving it some real punch for its size. The combined energy is 246 (moderate), and the wind is glassy – dead calm. That’s the standout for the first week. It’ll be clean as a whistle. But be warned, this break is for advanced surfers only, and crowds are possible, so get out early.
Sunday afternoon the 12th also looks promising with glassy conditions and a similar 3ft, 13-second ESE swell (239 energy). Another good option.
Now, for the second week, things get a bit more interesting but less certain. Thursday morning the 16th offers a glassy 3ft SE swell with a longer 11-second period (163 energy). Quiet, clean, but small.
The real standout of the whole outlook, however, is Sunday morning July 19th. That’s over a week and a half away, so take it with a pinch of salt, but the model is showing a 5ft E swell with an 8-second period. The combined energy is solid at 435 (moderate), and it’s glassy. That’s the best size we see in the whole period, and with no wind, it’ll be perfect. Monday the 20th and Tuesday the 21st also have decent 4-4ft E swells with glassy to clean conditions. Those last few days are the ones to circle on the calendar.
Stay safe out there.

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.
