Praia do Guincho (Guincho Beach) is a popular Atlantic beach located on Portugal's Estoril coast, 5 km from the town of Cascais, and is located in the municipality of Cascais, more precisely in the parishes of Cascais and Alcabideche, in the District of Lisbon. Guincho is nearby small villages like Areia, Charneca, Figueira do Guincho and historical Biscaia.
The beach has preferred surfing conditions and is popular for surfing, windsurfing, and kitesurfing. Strong northern winds are predominant during summer time (June–August) as well as smaller north-west swells, making this beach ideal for windsurfing and kitesurfing. During winter (especially December), the predominant winds are from the east, and swells increase in size, making it a perfect spot for surfing, with multiple beach-breaks providing powerful lefts and rights. There are also several surfcamps and surfschools in the area that provide accommodation and services including rentals, repairs and surfing classes.
