<P> Tundra climates ordinarily fit the Köppen climate classification ET , signifying a local climate in which at least one month has an average temperature high enough to melt snow ( 0 ° C ( 32 ° F ) ) , but no month with an average temperature in excess of 10 ° C ( 50 ° F ) . The cold limit generally meets the EF climates of permanent ice and snows ; the warm - summer limit generally corresponds with the poleward or altitudinal limit of trees , where they grade into the subarctic climates designated Dfd , Dwd and Dsd ( extreme winters as in parts of Siberia ) , Dfc typical in Alaska , Canada , parts of Scandinavia , European Russia , and Western Siberia ( cold winters with months of freezing ) , or even Cfc ( no month colder than − 3 ° C ( 27 ° F ) as in parts of Iceland and southernmost South America ) . Tundra climates as a rule are hostile to woody vegetation even where the winters are comparatively mild by polar standards , as in Iceland . </P>
