The Lowdown
Alright, grab a coffee and settle in. For the next 16 days, it ain't gonna be pretty. I’m looking straight at the forecast for Ponta Negra, and honestly, it’s a tough stretch. The word of the week is “cross-on” – that’s the wind direction we’re stuck with, and it’s gonna chop things up real bad. There’s swell on the cards, but the quality just isn’t there for a proper paddle session. We’re looking at a blank run for the whole window. Not a single day pops out as a good option. For an area like this, a run of poor conditions like this is actually pretty normal when the winds lock in from the south-east.
Let’s break it down. Starting from Thursday the 13th of August, right through the weekend, the wind is relentless, coming from the SSE to SE at 12 to 19 mph. The swell is mostly around 3 to 5 ft from the SE, with a short period of 6 to 8 seconds (combined energy moderate, between 139 and 473). That short period, onshore wind combo means nothing but messy, choppy slop. The water temp is sitting at 81°F with an anomaly of 1°F, which is pretty average for this time of year.
Next week doesn’t give any relief. From the 18th to the 24th, we stay in that same pattern. Winds ease a touch to 12 mph, but they’re still camping on-shore from the ESE. Swell sizes hover between 3 and 5 ft, mostly from the east with a short period of 6 to 7 seconds (combined energy moderate, 85 to 238). It’s still poor. There is no standout day, no hidden gem. The wind state is either “cross-on” or “unknown,” but none of it cleans up.
As we move into the final week, from the 25th of August onwards, it’s more of the same sad story. The swell bumps up a touch, hitting 5 ft on the 25th and 27th, but the period stays short at 6 to 8 seconds (combined energy moderate, up to 288). And that wind? Still cross-on or onshore from the ESE at 12 to 16 mph. The whole 16-day window is a write-off for surf. With the consistent onshore flow and short-period chop, this setup honestly looks far more interesting for kite surfing than for paddling out.
If you’re desperate for a wave, keep your eyes peeled for a change in the forecast, but for now, leave the board in the car.

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