syksyä
Syksyä is the partitive singular form of the Finnish noun syksy, which denotes autumn, the season between summer and winter in Finnish-speaking regions. The term refers to the period when temperatures cool, daylight hours shorten, and nature prepares for winter. In Finland, autumn commonly spans September through November in meteorological terms, while astronomical autumn runs from late September to late December. The season is known for autumn colors (ruska) as leaves turn yellow, orange, and red in many deciduous trees, and for increased rainfall and early frosts in the north.
Foliage changes and foraging are characteristic of the season: forests show ruska, berries ripen, and mushrooms
