Subpolar oceanic climate (Cfc)

Subpolar oceanic climate (Cfc)


CfcC = Warm temperate  f = No distinct dry season  c = Cool summer

Subpolar oceanic climates (Köppen climate classification Cfc) occur poleward of or at higher elevations than the maritime temperate climates and are mostly confined either to narrow coastal strips on the western poleward margins of the continents, or, especially in the Northern Hemisphere, to islands off such coasts. They occur in both hemispheres, most often at latitudes from 60° north and south to 70° north and south, specifically along the south coastal areas of Alaska, Iceland, Scandinavia and Argentina. Snowfall is more frequent and commonplace but severe weather is rare. Subpolar oceanic climates have long but relatively mild (for their latitude) winters and cool and short summers (average temperatures of at least 10°C for one to three months). The summers are shorter and cooler than temperate oceanic climates, but the winters are not as cold as the more inland Boreal comiates.


Flight planning and safety considerations

Maintain awareness of snowfall forecasts and runway clearance operations. Consider carrying contingency fuel in case of unexpected delays to approach while snow clearance operations are in progress. While severe weather is rare, be mindful of the risk of in-flight icing and the impact on aircraft performance, especially in the climb. Pay attention to temperature error correction when operating in low ambient temperatures.
