The weather of the province's coastal area has two well-defined seasons:
The sunny season, with temperatures of around 30°C (86.4°F), during daytime.
The "sunless" season (May–December), during which the sun is covered by clouds. The extreme humidity causes a sensation of cold during this season, even if the temperature never gets lower than 11°C (51.8°F).
The coast of Cañete, with beaches such as Asia, Chilca, Puerto Viejo, León Dormido,Costa del Campo, Totoritas, Chocaya, Chepeconde, Puerto Fiel, Gallardo and Cerro Azul, is one of the province's main touristic attractions. The pleasant valley of Lunahuaná, a paradise for adventure sports lovers, is just half an hour from San Vicente de Cañete. The main attraction is the fast running Cañete River, which features rapids up to Class IV. Each year, the valley hosts a festival involving rafting, trekking, gliding, mountain biking and fishing competitions. There are a few annual festivals in Cañete. The most important ones are Festival of Black Art in late August and Adventure Sports Festival in Lunahuaná, held in February.
