Nether Weathers

The Nether has an atmosphere of its own. Nether Weathers brings changing weather to all five Nether biomes, with drifting ash, falling spores, rising souls, colored fog, and immersive soundscapes.

From quiet sporefall in a Crimson Forest to a dense soulstorm sweeping through a Soul Sand Valley, each biome has its own weather identity. Clear periods give way to light weather or heavier storms, with effects that gradually build and fade.

Weather shaped by the biome

Weather fills the Nether’s open caverns without needing access to the sky. Effects become sparse in tunnels and low-ceiling areas, while soul particles can rise from the depths below you.

More than particles

Biome-colored fog makes each storm feel distinct, with heavier weather reducing visibility. Occasional colored flashes illuminate the atmosphere during storms, without spawning destructive lightning.

Continuous Nether ambience blends across biome boundaries, accompanied by particle-inspired sounds: ember crackles, fungal noises, escaping souls, and volcanic pops. The soundscape uses Nether ambience rather than Overworld rain audio.

Weather transitions smoothly, allowing particles, fog, and sound to build up and fade away naturally.

Make it your own

Open the settings through Mod Menu, or use /netherweatherconfig.

Set your preferences globally, then give individual biomes their own overrides. Customize:

• Light and heavy weather particle density.
• Fog strength and colored storm flashes.
• Ambient weather, particle accent, and thunder volume.
• Wind strength.
• Automatic wind or a fixed direction.

Settings apply without restarting. Keep the default atmosphere, turn storms into a subtle background effect, or adjust each biome to suit your style.

Natural cycles and command support

Nether weather runs independently of Overworld weather. Clear periods naturally alternate with lighter weather and less frequent heavy storms, and the current weather and remaining duration are saved with the world.

The familiar vanilla commands work when executed in the Nether:

/weather clear
/weather rain
/weather thunder
/weather thunder 60s

You can also use /netherweather clear, /netherweather rain, or /netherweather thunder to control Nether weather from another dimension, and /netherweather query to check its current state.

Weather commands require operator permissions.

Multiplayer

The server controls the weather cycle and synchronizes it with players. Each player can customize their own particles, fog, wind, and audio without changing the shared weather state.

Install the matching version of Nether Weathers and its required dependencies on both the server and participating clients.
