The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the next week and a half is looking pretty grim. We’ve got a long stretch of tiny, chopped-up surf ahead. If you’re thinking about getting wet, you’ll be doing more fighting than gliding. This stretch looks more interesting for kites than for paddle surfing.
The one day to circle on the calendar is Friday, the 14th of August. That morning, things finally click. We’re looking at a 2ft swell from the southeast with a long 14-second period. That’s proper groundswell. The wind is light and offshore from the west, leaving the surface glassy. This is your window. Praia Grande will be the spot. It’s not going to be big, but it’ll be the cleanest, most lined-up surf we’ve had in ages.
Before that, there are a few mornings that are “nearly” but not quite. Saturday the 8th and the morning of the 13th have some clean conditions, but the swell is just too weak to be worth the drive. Those are for the locals who live on the beach, not for a special trip. After that Friday high point, the weekend and the second week fade back into the same old story – onshore winds and small, lumpy surf.
So here’s the deal: be patient, wait for Friday the 14th, and you’ll be rewarded. The water temp is about normal for this time of year, so a wetsuit is fine. That’s the one to go for. Everything else is a write-off.
Rusty out.

Information about the Praia Grande Surf forecast
The above surf forecast table for Praia Grande provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia Grande can be found by selecting the local surf guide option on the grey menu. Our Praia Grande 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 Grande) 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 Grande 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 Grande is 20 km (12 miles) from Paranagua. If you plan a holiday in Paraná, look for hotels and other accommodation in Paranagua. Paranagua has rooms for a wide range of budgets as well as car hire and transport links.
