Alright, let’s break this down for Praia do Porto. Rusty here.

Monday morning is a bust. Cloudy, a messy 4ft cross-on swell, just ugly. The ocean’s got some energy (611) but it’s poor. Come Monday afternoon, a light offshore from the SSW cleans up that same 4ft SE swell. It’s not big, but it’s clean and surfable. That’s your first real window.

Tuesday morning looks better. Clear skies, light offshore from the SW, and a 5ft swell from the south at 8 seconds. The short period means the waves are a bit soft, but it’s fun for a beginner-plus level. Energy is moderate at 468. Tuesday afternoon the wind goes cross and it fades.

Wednesday morning is the highlight of the first half. Glassy, light west wind, and a 4ft south groundswell at 12 seconds. That long period means proper waves with more push – you’ll feel that 597 energy. It’s a beach/jetty setup, so with the long period it might straighten out a bit, but it’s going to be clean and fun. Wednesday afternoon the wind goes onshore and it’s average.

Thursday and Friday are small and weak – Thursday morning drops to 3ft, Friday has a glassy 3ft but it’s weak. Nothing to get excited about.

Now, here’s the juice. Sunday the 12th of July. Morning has a light cross-off breeze, a 4ft south swell at 12 seconds, and the energy jumps to 856. That’s proper. The afternoon brings a 5ft south swell with offshore winds at 9 mph, still 12 seconds, energy at 847. Very good, clean surf. Crowds are possible, but it won’t be packed.

Monday the 13th of July is for experts only. A big 10ft south swell hits, short period at 9 seconds, and the energy is huge – 1750. Strong offshore winds at 22 mph keep it clean, but 10ft is serious power. Not for beginners. Same for Monday afternoon.

Tuesday the 14th of July drops to 8ft from the SSE at 11 seconds, still big but more manageable. Offshore winds from the WSW at 12 mph, energy at 1322. Still high-energy, but better shaped. Good for experienced surfers.

After that, the swell backs off to 6ft on Wednesday the 15th, with a cross-off wind in the morning keeping it clean. From Thursday the 16th onward, the wind turns onshore from the NNE and the surf fades. From the 16th through the 21st of July, it’s mostly poor – choppy, onshore, or just small. The 19th has a 10ft NE swell, but with howling onshore winds, it’s a blown-out mess. Not worth it.

So, the pick: Wednesday morning the 8th of July for the cleanest, glassy, long-period session. Sunday the 12th of July is the best overall – great size, clean offshore flow, and solid energy. That’s your call.

Rusty.

Information about the Praia do Porto Surf forecast

The above surf forecast table for Praia do Porto provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia do Porto can be found by selecting the local surf guide option on the grey menu. Our Praia do Porto 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 (Praia do Porto) 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 Praia do Porto 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.

Praia do Porto is 2 km (1 miles) from Imbituba. If you plan a holiday in Santa Catarina - Sul, look for hotels and other accommodation in Imbituba. Imbituba has rooms for a wide range of budgets as well as car hire and transport links.
