High Voltage

A weather overhaul that makes storms more immersive, atmospheric, and dangerous.

High Voltage expands Minecraft's weather system with custom precipitation, atmospheric fog, biome-specific climates, environmental hazards, and dynamic storm effects.

The mod includes a complete set of built-in weather profiles out of the box, so no configuration is required. Simply install the mod and experience a more varied and immersive world.

For players, High Voltage is a weather overhaul.

For pack makers, it's a fully data-driven weather framework.

Vanilla+ Weather

High Voltage is designed to feel like a natural extension of Minecraft's weather system.

Instead of adding tornadoes, survival mechanics, or complicated weather simulations, High Voltage focuses on making storms more interesting, atmospheric, and biome-specific while staying true to vanilla gameplay.

You'll still recognize Minecraft's weather but now different regions of the world can have their own identity.

A snowy biome might experience freezing blizzards.

A swamp might become covered in dense fog.

A forest storm might bring increased lightning activity.

The goal isn't to replace Minecraft's weather with an entire overhaul.

It's to make it feel like it was always meant to be this way.

Features

Built In Weather Overhaul

High Voltage comes with its own weather profiles and environmental effects, adding variety to storms across the world without requiring any setup.

Different biomes can experience unique weather conditions with their own visuals, atmosphere, and gameplay effects.

Custom Precipitation

Weather is no longer limited to vanilla rain and snow.

High Voltage supports:

• Custom precipitation textures
• Colored precipitation
• Variable fall speeds
• Landing particles
• Landing sounds
• Rain-like or entirely custom weather behavior

Atmospheric Fog

Storms can dramatically alter visibility using custom fog rendering.

Examples include:

• Dense blizzards
• Coastal mist
• Swamp haze
• Volcanic ash clouds
• Magical fog banks

Dynamic Weather Effects

Weather can directly impact gameplay.

Built-in effects include:

• Freezing
• Burning
• Damage over time
• Status effects
• Lightning events
• Entity summoning
• Attribute modification
• Sound events
• Command execution

Storms become more than visual decoration, they become hazards.

Biome-Specific Climates

Each biome can have its own weather profile.

A snowy mountain may experience blizzards while a nearby swamp is covered in thick fog.

Weather becomes part of a biome's identity instead of a global effect.

Datapack Support

Everything used by High Voltage's built-in weather system is exposed through data-driven codecs.

Modpack creators and datapack authors can:

• Create entirely new weather profiles
• Customize existing profiles
• Add custom weather effects
• Change precipitation visuals
• Configure fog behavior
• Control lightning frequency
• Target specific biome groups

No coding required.

Weather profiles are loaded from:

data/<namespace>/weather_profiles/

Documentation: High Voltage Documentation

Built In Diagnostics

High Voltage includes datapack error reporting.

When a weather effect fails to load, the game can automatically detect:

• Missing effect types
• Invalid IDs
• Misspelled parameters
• Unexpected fields
• Parsing failures

Making weather profile creation significantly easier to debug.

Perfect For

• Vanilla+
• Adventure packs
• RPG modpacks
• Fantasy worlds
• Custom dimensions
• Biome overhauls

Whether you want a weather overhaul or a fully customizable climate system, High Voltage provides both.
