The climatic patterns of Newfoundland and Labrador are discussed here season by season,
and are illustrated by maps and graphs. The map of Climate Zones below provides a spatial
framework for this study of the annual cycle.

Tundra climate - summers too short and cool to support
full tree growth. Precipitation decreases toward north. Mountains and
fjords create locally variable weather conditions, especially
Most continental of the province's climate regimes. Lengthy,
very cold winters with deep snow cover but relatively more settled weather
patterns. Upper Lake Melville area has relatively shorter winters and warmer,
Exposed to stormy or unsettled weather from Labrador Sea.
Heaviest precipitation normally south of Groswater Bay. Occasional
extremes of temperature during offshore wind directions in summer
Marine influence from Gulf of St. Lawrence normally
reduces temperature extremes but causes increased precipitation,
especially during fall and early winter, when snowfalls are most
frequent. Locally severe wind speeds descend from Long Range
Mountains during favorable winter weather patterns.
||Western Mountains and Central Uplands
Increasing elevation normally results in lower temperatures,
greater cloudiness and precipitation and stronger winds. Heavy winter
snow accumulations, especially toward west.
Northeast Coast and Central Lowlands
Driest area on island. Occasional very low winter
temperatures in valleys. Cool, late spring near the coast, where
sea ice often persists into May. Generally warm and
South Coast and Avalon
Relatively mild winters with considerable variation in snow cover.
Heavy rainfalls from October through December. Summers cooled by low clouds
and fogs near coasts, considerably brighter and warmer inland.
