Sitting right on the Atlantic coast west of Lisbon, Cascais gets steady sea breezes that keep it slightly drier than the hills of nearby Sintra, though winter storms sweeping in off the ocean can still bring sudden, sharp downpours. The exposed coastline means wind-driven rain and swell often arrive together during the wet season. IPMA maintains coastal radar coverage along this stretch of the Estoril coast.
