The Lowdown
Alright folks, Rusty here. Let's have a look at what Costa Nova has in store for us over the next couple of weeks.
It’s a tough stretch ahead, I won’t sugarcoat it. For the vast majority of the 16-day window, we’re looking at either tiny, weak surf, or blown-out conditions. There’s a long dry spell for decent waves, but just when you think it’s all over, a little window of opportunity might open up right at the very end.
The first action we see is on the morning of Thursday the 30th of July. This is the one to keep an eye on. The wind is forecast to swing offshore from the ENE, which is a big deal for this spot. That will clean things up nicely. We’re looking at some waist-to-chest high swell, around 5ft, coming from the NNW. The combined energy is moderate at 225, so there will be some push to it. The water temp is sitting about average for the time of year at 65°. This is the standout of the whole forecast, and it’s the only time the conditions really come together for a decent paddle. However, after that morning window, the wind swings cross-onshore and the swell gets a bit bigger, up to 6ft, but it turns messy.
Before that, from Wednesday the 15th right through to the morning of Wednesday the 29th, it’s pretty flat and grim. For nearly two full weeks, there’s just no quality to be found. We get occasional pulses of chest-high swell around the 20th and the 25th of July, but the wind is never in the right spot. It’s either glassy with almost no swell, or there’s a little bump but blown sideways. The periods are generally short, under 8 seconds, so the waves are weak and crumbly.
The afternoon of Thursday the 30th sees the swell pushing into the 6ft range, which is getting a bit too much grunt for beginners, but with the cross-onshore wind it’s going to be a choppy mess. Probably more of a kite session than a surf session by then.
So to sum it up: if you’re keen, pencil in the morning of Thursday the 30th of July. Get there early for the offshore wind and clean lines. The rest of the month is a write-off.
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.
