Serene Seasons Plus Mod (1.21.11, 1.20.1) – Survive Harsh Winters Serene Seasons Plus Mod extends Serene Seasons with realistic snow piling and changing day lengths. Snow piles up in layers during snowfall and melts away layer by layer instead of disappearing at once. The mod also shifts day and night hours across the seasons when paired with compatible mods. It even includes a preset based on real-world winter weather in Montreal.

Features:
- Realistic Snow Piling: Snow builds up layer by layer during snowstorms instead of covering blocks all at once.
- Gradual Melting: Snow blocks lose one layer at a time as temperatures warm up instead of vanishing immediately.
- Per-Player Processing: Snow layers update around each active player rather than forcing updates across the entire world at once.
- Winter Depth System: Early winter snow resets the counter and sets a random average snow depth for different areas.
- Changing Day Lengths: Pairs with Better Days so day and night lengths shift throughout the year.
- Montreal Climate Preset: Matches real-world seasonal timing based on Montreal weather data.
- Works alongside Project Atmosphere so snow only gathers directly under snowy clouds.
