Aequinoctium - Weathers and Seasons
by Arindel

This is a backport of the Skyrim Special Edition version of this mod.
Because effects like Godrays, SSR or Ambient Occlusion are missing, the mod will not look the same.

A soft, fantasy/realistic hybrid weather overhaul featuring seasonal weathers, shorter days during winter and interior rain sounds. Aequinoctium strongly emphasizes the visuals with each season having their own looks and feels, making the experience fresh every season.

About seasons
Each season has a specific set of weathers and each set look differently to create a certain mood that matches the season.

Spring - This is the most balanced in terms of colors, looks the most natural and weathers have balanced chances. May or may not snow.
Summer - Summer is hot and the warmer sunlight reflect that. The rain storms start occurring until the first month of autumn, but how often they'll occur is based on a randomized chance. It will not snow at all except in snowy regions.
Autumn - During autumn you will experience more dread looks, as if everything look depressing. Overcasts and rains will occur much more often. Snow is a possibility.
Winter - Winter is coming or so they would say. The weathers look more livelier than autumn, but colder. Snow start falling down and days are getting shorter.

What does randomized chances mean?

At the beginning of each month the weathers chances are changed through script. For example, in September the rain storms can achieve a chance between 0% and 25%. That means there's always a possibility of storms never occuring. However, the next September may actually get some rain storms.
There's more like this such as with snowing during spring or how often overcast/rain weathers occur during autumn.

Does this provide snow accumulation or trees changing based on season?
Unfortunately, no. I don't know for sure if it's even possible, but if it is, I don't have the experience to make this.

How does seasons work exactly?
Through script which changes each weather's chance according to the month. It's a simple concept.
For as minimum impact as possible on performance, the script is triggered only in 3 ways. On Load Game, Player Sleep and through a hidden player ability that triggers the script when month changes.


NOT compatible with the following:
  • Other weather mods
  • Mods that make nights darker (these are fundamentally weather mods)
  • Mods that add new sounds such as Sounds of Skyrim or Audio Overhaul (those change the same areas used for seasonal weathers)
