The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the menu for Prainha over the next couple of weeks.

First off, we’ve got a bit of a rough start. Thursday the 3rd is a write-off: the wind is messy and the surf is poor. We’re looking at a couple of days of nothing really worth paddling out for, so save your energy.

The first real glimmer of hope comes on Friday morning, the 4th. The swell drops to a clean 3 ft from the SE, and with a cross-offshore breeze, it’ll be a lot cleaner. Not a standout, but a nice little session for someone who’s keen on an intermediate wave. The water is sitting at 67°, which is pretty normal for this time of year.

Now, if you’re looking for the real highlight of the whole outlook, you need to circle Monday the 7th – the morning session. The wind is glassy, just a light breath from the WSW, and the swell is a solid 7 ft from the SSE. That’s a proper groundswell with a period of 8 seconds, and the combined energy is moderate (570). The conditions are set up for a clean, glassy morning. This is the best on offer. But keep in mind, at 7 ft, this is getting into the territory where it’s more for the experienced crew; beginners might want to sit this one out.

The middle of the week from the 8th to the 10th is a bit of a mixed bag, with onshore winds and choppy conditions. Not much to write home about.

We do have a solid pulse of energy showing up for the 13th and 14th. Sunday the 13th afternoon sees a 7 ft swell from the S with a 10-second period, producing a strong energy reading (1065). The wind is cross-off, so it’ll be clean. And then Monday the 14th morning – watch out. The swell is predicted to hit 10 ft from the S. That’s a big, powerful wave. The wind is light cross-on, but the forecast says it’s probably too big for this break. Only for the most experienced, and even then, it’s a gamble.

Looking further out, the 15th and 16th settle down a bit. Wednesday the 16th morning is a gem: glassy, calm winds, with a clean 3 ft wave from the S. A perfect little session for everyone.

The final shout goes to Friday the 18th. The afternoon session is the standout of the second week. A 6 ft swell from the SSE with a very long period of 15 seconds, and a massive combined energy of 1295 – that’s strong. The wind is cross-off and clean. This is excellent surf for experienced surfers. The long period means it’s going to be a proper groundswell, with lots of energy and long walls. At a beach break, it might break a bit straight, but for an experienced surfer, the power and shape will be there. A promising note to end on, but it’s a way off, so keep an eye on the forecasts.

So, if you’re picking a day, go for the glassy morning of Monday the 7th. That’s your best bet for quality. For the brave, the 18th looks like a barnstormer, but it’s a long-range call.

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 17 km (11 miles) from the city of Tijucas. If you plan a holiday in Santa Catarina - Norte, look for hotels and other accommodation in Tijucas. Tijucas has rooms for a wide range of budgets as well as car hire and transport links.
