The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming up for the Costa Nova stretch.
Right off the bat, we’ve got a rough start. The first few days are a write-off with poor conditions and messy onshore chop. The water is sitting at a very warm 71° – that’s 5° warmer than usual for this time of year, so it’s feeling like a bath out there.
The real window opens Monday morning, 27 July. That’s our standout. Costa Nova (beach/jetty) will be clean with glassy conditions. Swell is a small but clean 2ft from the NNW, with a period of 11 seconds. That’s a nice little groundswell pushing through, and the combined energy is moderate (209). It’s not going to be huge, but with the wind off the land and zero bump, it’ll be the best session of the week. Expect crowds sometimes.
Tuesday morning, 28 July, is another solid shout. Again, glassy conditions with a light WSW breeze. Swell picks up a touch to 4ft from the NW, period 10 seconds, and the energy is moderate (300). It’s a clean, fun morning.
After that, conditions get onshore and choppy through the rest of the week. There’s a brief window of surfable but ordinary waves on Thursday morning, 30 July and Friday morning, 31 July, but with only 1ft to 4ft of swell and messy wind, it’s not one to get excited about.
Saturday morning, 1 August, sees a bump in size to 5ft from the NNW, but with a cross-shore wind and only 9-second period, it’s a marginal call. The energy is moderate (411), but the wind kills the quality.
Monday morning, 10 August, is the second standout. A glassy morning with a 4ft swell from the west, period 10 seconds, and moderate energy (272). Clean conditions again. That’s a long-range call, so keep an eye on it – it’s promising but not set in stone.
Overall, it’s a patchy forecast. The first two weeks are mostly poor, with a few glassy mornings that’ll deliver clean, small waves. If you’re keen, hit Monday the 27th or Tuesday the 28th. For the more adventurous, the 10th of August is worth watching.
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.
