Praia da Costa Nova is generally considered safe for swimming, particularly during the warmer months when lifeguards are typically on duty. The wide sandy expanse offers plenty of space for families. However, as with any ocean beach, conditions can vary, so it's always advisable to observe any posted flags or warnings and supervise children closely. The waves can sometimes be moderate, making it enjoyable for various water activities.

Praia da Costa Nova is beautiful any time of year, with its iconic striped houses providing a charming backdrop. For the best weather conditions for sunbathing and enjoying the beach, the summer months (June to September) are ideal. If you want to capture photos of the houses without large crowds, visiting during the shoulder seasons (spring or early autumn) or on weekdays can offer a more relaxed experience, though some services might have reduced hours.

Praia da Costa Nova is easily accessible by car from Ílhavo or Aveiro. There are often designated parking areas available, though during peak summer months and weekends, these can fill up quickly. Public transport options, such as local buses, also connect Costa Nova to nearby towns like Aveiro, making it feasible to visit without a car. Cycling paths are also popular for those staying in the vicinity.

Praia da Costa Nova offers a good selection of food and lodging options. You'll find numerous restaurants and cafes serving fresh seafood and traditional Portuguese cuisine, many with outdoor seating. For accommodation, there are guesthouses, holiday rentals, and a few hotels, some of which are located within the charming striped houses themselves, offering a unique stay. It's advisable to book in advance, especially during high season.

The striped houses of Praia da Costa Nova are incredibly unique due to their vibrant, vertical or horizontal stripes painted in bright colors like red, blue, green, and yellow on a white background.
