Costa Nova Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it. We’re looking at a long-range window for Costa Nova, and honestly, the first week is a bit of a grind. We’ve got some waiting to do, but there’s a real standout deep in the forecast that’s worth hanging on for.

The first decent chance doesn’t roll in until the morning of Saturday the 12th. It’s not going to set the world on fire, with a small 3ft swell from the NNW and pretty weak combined energy (163). The wind is glassy though, dead calm, so it’ll be clean. For a weekend paddle, it’s rideable, but nothing to write home about.

Sunday the 13th morning is where the window starts to crack open. A 4ft groundswell from the NW with a nice long 12-second period hits, and the combined energy jumps to 481. The wind is glassy, and the conditions are looking good. This is a solid morning session. The water temp is about 68°, which is a touch warmer than average for this time of year, so comfortable.

Monday the 14th morning keeps that clean feel with a glassy 3ft swell from the NW, period hanging around 11 seconds. It’s a smaller, clean option, but the energy is moderate (275). Good for a longboard.

Now, the real highlight is the morning of Thursday the 17th. This is the one. We see a 6.6ft NW groundswell with a 11-second period pumping in, and the combined energy is a solid 898. The wind is offshore from the ENE, light breeze, making for clean surf. That’s a proper session. It’s a bit on the bigger side for beginners, but intermediate and up will be stoked. The jetty could be working nicely.

After that, it gets a bit messy again. We get a glassy morning on Friday the 18th with a smaller 4.6ft NNW swell, but the wind turns cross-onshore in the afternoon. Keep an eye on the 24th of September, Thursday morning. There’s a big 7.5ft NNW swell coming, but the period is short at 7 seconds, so it will be a bit crumbly. The cross-offshore wind from the SSE will keep it clean, and the energy is strong (550).

And then, the one to truly circle on your calendar: the morning of Friday the 25th of September. A massive 11.5ft swell from the NW with a 15-second period is on the cards. The combined energy is a whopping 8888. The wind is light and cross-offshore from the south. This is a serious, powerful groundswell. However, at this size, it’s only for experts. It’s predicted to be too big for Costa Nova, so unless you are a seasoned charger, it’s a watch-and-spectate day. The power and length of those sets will be unreal.
