Alright, Rusty here. Let’s size up Costa Nova for the next 16 days.

Honestly, it’s a pretty quiet outlook overall. The first week is mostly small swell and messy wind – nothing to get fired up about. The best chance comes later on, but it’s a ways off and not locked in yet.

First chance to paddle out is Friday morning, July 3rd. We’ve got a 2ft NW swell with an 11-second period – that groundswell will have some push. Wind is light cross-offshore from the NE at 6 mph, keeping things clean. Combined swell energy is moderate at 249. Water temp is about 65°, normal for the season. This is a beach and jetty setup (Costa Nova), and crowds can pop up. Morning window is your best bet.

After that it goes flat and funky. Saturday July 4th morning is glassy with a 2ft WNW swell, period 10 seconds, and no wind – clean but weak, energy only 146. Surfable but nothing special. From Saturday afternoon all the way through Friday July 10th, the swell stays tiny and the wind turns cross-onshore or onshore almost every session – a real gap of several days with nothing worth wading in for. Swell rarely hits 2ft in that stretch.

Things try to pick up Saturday July 11th morning with a 2ft NW swell and 11-second period, energy 153, but the wind is cross-on and lumpy – still poor quality. Afternoon no better.

Sunday July 12th morning jumps to 6ft from the NNW, but the period is short at 8 seconds, and the wind is cross-shore from the south at 6 mph. Energy is strong at 411 – but it’s a short-period windswell, messy on a beach break. Not clean enough to get excited about. Afternoon is onshore junk.

Monday July 13th morning still has 5ft from the NNW with a 7-second period – energy 268 – but it’s choppy and cross-on. The rest of that week stays small and poor. A few glassy mornings around Thursday July 16th are tiny – 3ft, weak (84 energy) – surfable but very ordinary.

Now here’s the one to keep an eye on: Friday July 17th morning. Swell hits 5ft from the west, period 9 seconds, with light NNW wind at 6 mph – cross-on but light. Combined energy is 377 – strong. That’s the biggest, most energetic swell of the forecast. It’s a beach break so might be a bit crumbly, but it’s the best of the bunch. Saturday July 18th morning still has 4ft from the WNW, period 9 seconds, light winds – energy 261 – also worth a look.

Just remember, these late sessions are over a week out – promising but not set in stone. For this stretch, that Friday the 17th is the one to pencil in.

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.
