The Lowdown

Alright, Rusty here. Let’s have a look at what’s on offer.

To be straight with you, the next week and a half is pretty average. There’s a lot of onshore wind and messy conditions in the mix. You’ll have to be patient and pick your windows carefully. The best bet looks like Friday the 7th and then again around Friday the 14th and Saturday the 15th, but those are still a fair way out.

Right now, Sunday the 2nd is flat with poor surf – not even worth looking at. Monday the 3rd and Tuesday the 4th stay small and choppy, with wind ruining any chance of a decent wave. Wednesday the 5th is more of the same: small swell and cross-onshore wind. Nothing worth getting excited about.

Thursday morning the 6th shows a little more energy (209 combined energy), but it’s short period and cross-onshore, so it’s only marginal at best.

Now, Friday morning the 7th is where it gets interesting. We’ve got clean, glassy conditions at Costa Nova (beach/jetty). The swell is 4ft from the NNW, period around 8 seconds, and the combined energy is moderate (226). It’s not huge, but the glassy morning will make it feel way better than it looks on paper. This is a window for the intermediate surfer to get some fun ones. The break is fairly consistent, and crowds can happen sometimes, so get in early. The water temperature is about average for this time of year, so no surprises there.

Saturday the 8th and Sunday the 9th go back to messy with onshore winds, though Sunday morning has a brief glassy window with 3ft swell – surfable but very ordinary.

Monday the 10th sees a bump in size (5ft) but it’s blown out by strong NNW winds up to 30 km/h. This is looking more interesting for kite surfing than a proper paddle session. Tuesday the 11th morning cleans up again with glassy conditions and 3ft from the NNW, but it’s small and average.

Wednesday the 12th through Thursday the 13th are tiny and poor. Thursday morning the 13th has a glassy 2ft – barely worth a splash.

Then we get to Friday morning the 14th. This one stands out. Costa Nova (beach/jetty) has 5ft from the NNW, glassy conditions, and combined energy of 281 – moderate to strong. Period is short at 7 seconds, but the clean morning and that push of energy will give some punchy little waves. It’s a good option for intermediates. This is one of the better windows in the whole outlook.

Saturday morning the 15th follows up with 6ft from the NNW, glassy, combined energy of 240. The size is getting up there – more than 5ft, so beginners might find it a bit much, but for intermediates it could be fun. The short period (6 seconds) means it’ll be a bit crumbly, but still rideable in the clean conditions.

After that, Sunday the 16th and Monday the 17th drop back to small, poor surf with cross-shore winds. The run fades out.

So, to wrap it up: the standout is Friday morning the 7th for clean, fun-sized waves, and then the mornings of Friday the 14th and Saturday the 15th look promising too, but they’re further out so keep an eye on the forecast.

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.
