Table - best surf conditions forecast for Costa Nova over the next 16 days.
Alright, let's get real about what's happening at Costa Nova. For the next 16 days, this is the only spot we've got, and it's a slow starter.
From now until Monday, July 22nd, it's pretty grim. The wave energy is weak, barely cracking triple digits (moderate energy) once or twice, like Saturday morning, July 11th, but that's the exception. Winds are mostly cross or onshore, and the swell is tiny - mostly under 3ft. Water temp is 65°, which is dead average for the season. There's just nothing to get excited about. If the wind gets going, this is a better bet for kite surfing than paddle surfing.
The first little window shows up on the morning of Monday, July 20th. We get a 3ft swell from the NW with glassy conditions. That's clean. Combined energy is at 132 (moderate wave energy). It's ridable but ordinary. The glass won't last into the afternoon.
Now, the real highlight lands on Thursday morning, July 23rd. This is the one to wake up for. A solid 6ft swell from the NNW, with an 8-second period. That's overhead for the bigger guys. Combined energy is cranking at 391 (strong wave energy). And the wind is light cross-offshore, making for clean, lined-up waves at Costa Nova (Portugal). Friday morning, July 24th, is nearly the same: 6ft from the NNW, light cross-offshore wind, energy at 393. Also clean. This is for the intermediates and up - 6ft is pushing into the expert zone. It's a beach/jetty setup, so with that period, it might be a bit straight. Crowds are possible.
The afternoons after those mornings get blown out with strong cross-shore winds, so early is the call.
Nothing before that's worth paddling out for. Those last two mornings are the real promise, though it's a long way out so we'll see how it firms up.

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.
