The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on offer for Costa Nova over the next couple of weeks.

Right off the bat, we’ve got a bit of a flat spell to start. The first few days are pretty ordinary, with small, short-period wind swell and mostly onshore or cross-onshore winds messing things up. The water’s sitting at a mild 68°, which feels a touch warmer than normal for this time of year. Not much to get excited about, honestly.

We've got a little bump in size around Saturday the 26th and Sunday the 27th, with the swell building to around 6 ft to 6 ft, but the wind is a problem. It's mostly cross or cross-onshore, and the period is short (6-7 seconds), so it'll be lumpy and choppy. The combined energy climbs up to the mid to high 200s (277) on Sunday morning, but with those winds, it's a pass for me.

Right, here’s the standout. The absolute best window looks like the morning of Monday, July 28th. The wind drops out completely – glassy conditions, calm as can be – with a clean 4 ft swell coming from the NNW. The combined energy is still a solid 273. It’s a beach/jetty setup, so with that light period, it should be fun and clean. Just keep in mind this spot can get crowded sometimes.

The following week starts to show some promise further out. We see a bigger pulse of swell moving in around Tuesday, August 5th. The morning of Wednesday, August 6th, is another real highlight. We’re looking at 6 ft of NW groundswell (10-second period) with zero wind – dead glassy. The combined energy is pumping at 609. That’s a solid, powerful swell with clean conditions. This one is for the experienced crew, as it’s a bit of size. It’s still a long way out, so treat that one as a promising but not locked-in prospect.

Before that, the morning of Tuesday, August 5th, also looks interesting with 6 ft swell and light cross-shore wind, but the real jewel is that Wednesday morning.

For the beach breaks, with the longer period groundswell later on, the waves might be a bit too straight for the beach, so keep an eye on the jetty for a better line. If the wind gets messy again on the bigger days, the setup here could be more fun for a kite session than a paddle.

So, get the small boards ready for that glassy Monday window, and keep your fingers crossed for that big Wednesday towards the end of the run. That’s the one to circle on the calendar.

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.
