Alright, Rusty here. Let’s have a look at Costa Nova.
Honestly, the first couple of weeks are a tough watch. We’ve got a long, flat spell with hardly any energy. For days on end, the wave is tiny, the wind is messy, and the conditions just aren’t worth paddling out for. You’re looking at a real dry run from Tuesday the 7th right through until pretty much the end of the week after that. A few mornings might tease you with a little pulse, but the combo of small swell and cross-onshore chop makes it a frustrating wait. Don’t bother.
The only real glimmer in that first stretch is Saturday morning, July 11th. The combined energy is still weak, only 115, with a 2ft WNW groundswell pushing through at a nice long 11-second period. The wind? Glassy. Absolutely dead calm. That’s a rare treat for this stretch and it’ll be clean, even if the waves are small. For a patient surfer on a log, that morning might offer a quiet, glassy session all to yourself. But keep your expectations low on size.
Now, fast forward to the second week, and there’s a bit more life. The real standout is Tuesday morning, July 21st. We get a 6ft swell from the NNW (moderate energy at 356 – starting to get some real grunt), with glassy conditions again. That north-west angle with zero wind makes for clean faces. The period is a short 7 seconds though, which means it’ll be a bit lumpy and close together – more of a punchy beach break. At nearly 6ft, that’s expert territory.
Then Wednesday morning, July 22nd, offers another chance. The swell holds at 7ft from the NNW, but here the wind swings around to a light SSE cross-offshore, cleaning the waves up nicely. The combined energy is up at 491, so there’s some proper push. Again, short period means raw power rather than long lines. This is for experienced surfers only.
So there you have it. The first week is a write-off. The standout is Tuesday the 21st morning, with glassy conditions and real size, but it’s big and punchy. If you’re an expert and you can wait, that’s your window.
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.
