Table - best surf conditions forecast for Costa Nova over the next 16 days.
G’day, Rusty here. Look, I’ve had a proper look at what’s coming up for Costa Nova over the next couple of weeks, and to be honest, it’s a bit of a slow burn. Most of the time, we’re staring at pretty ordinary, small, and choppy conditions. You’ll need some patience. There’s a long stretch from now until the middle of next week where you’d be better off doing something else with your time.
The first sniff of anything worthwhile doesn’t show up until Monday the 20th of July. That morning things change. We’ve got a clean 5ft swell rolling in from the NW with light offshore wind from the East – that’s the good stuff for this beach/jetty setup. The combined energy reads at 227 (moderate). It’s a bit of a standout because the wind finally gets it right, but the swell is just at that point where it’s pushing into intermediate territory. Crowds are *sometimes* an issue here so you might have company.
Then, blink and you’ll miss the real gem. Tuesday the 21st of July, first light is your absolute best bet. A glassy morning with a clean 4ft swell out of the NNW, and the combined energy kicks up to 292 (still moderate but feeling punchy). The period is 8 seconds, so it’s a short-period wind swell, nothing too drawn out, but with that glassy surface and offshore wind? That’s a proper window of clean waves. After that, the wind swings back onshore and it turns messy again.
Thursday the 23rd of July is a write-off, and Friday the 24th of July sees some size come in – 5ft to 7ft – but the wind is cross-onshore and it’s just messy. That’s more of a kite-surfing setup than a paddle session. The same goes for Saturday the 25th of July, 5ft to 5ft but all chopped up by moderate winds.
So, if you’re keen, point your board at Costa Nova. The real standout is Tuesday the 21st of July morning. Get out there for that glassy, clean 4ft swell before it gets blown out. The water temp is sitting around 64°F right now, which is 1°F cooler than average – nothing dramatic, just a touch on the fresh side.
Keep your eyes on the forecast though, because after a run of flat nothing, things can change.
Rusty.

Information about the Costa Nova Surf forecast
The above surf forecast table for Costa Nova provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Costa Nova can be found by selecting the local surf guide option on the grey menu. Our Costa Nova 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 (Costa Nova) 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 Costa Nova 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.
Costa Nova is 8 km (5 miles) from the city of Ilhavo. If you plan a holiday in Beira, look for hotels and other accommodation in Ilhavo. Ilhavo has rooms for a wide range of budgets as well as car hire and transport links.
