Overview
inZOI features four seasons (Spring, Summer, Fall, Winter) that cycle every 28 in-game days, with each season lasting 7 days. Seasons affect weather, available activities, NPC behavior, and the overall atmosphere. Dowon experiences all four seasons with distinct temperature shifts, while Bliss Bay and Cahaya maintain warm climates year-round. Seasonal events were introduced starting in v0.5.0.

Move to Bliss Bay or Cahaya if you want to avoid cold-weather management entirely.
