An oceanic climate (also known as a marine or maritime climate) is characterized by cool summers and cool winters, with a narrow annual temperature range and few extremes due to maritime influence. Oceanic climates can be found between 35° and 60° north and south of the equator, primarily on the western sides of continents and in isolated locations.

Oceanic climates have a monthly mean temperature below 22 °C (72 °F) in the warmest month, and above 0 °C (32 °F) (or −3 °C (27 °F)) in the coldest month. Precipitation is evenly dispersed throughout the year, as the constant influx of stable maritime air means that oceanic climates lack the hot,dry summer of the Mediterranean climate, or the humid summers of the humid subtropical climate.

Oceanic climate dominates in much of Western Europe, the Pacific Northwest region of the United States and Canada, parts of central Mexico, southeastern South American and southeastern Australia including Tasmania and New Zealand.
