Rain Limiter

Rain Limiter is a lightweight server-side NeoForge mod that gives server owners more control over Minecraft weather without completely disabling it.

Instead of allowing rain and thunderstorms to continue for long periods, Rain Limiter lets you define the maximum duration of rain, the maximum duration of thunderstorms, and the minimum amount of clear weather required before bad weather can return.

This makes it ideal for multiplayer servers, modpacks, building servers, roleplay servers, or anyone who finds Minecraft's weather a little too frequent.

Features

• Set a maximum duration for normal rain.
•  Set a separate maximum duration for thunderstorms.
• Set a minimum clear-weather period between storms.
• Change all timings while the server is running.
• Settings are saved and remain after server restarts.
• Lightweight and designed for minimal performance impact.
• Server-side only — players do not need to install the mod themselves.
• Operator-only configuration commands.
• Supports seconds, minutes, and hours.

Default Settings

By default, Rain Limiter uses:

• Maximum rain duration: 5 minutes
• Maximum thunderstorm duration: 5 minutes
• Minimum clear duration: 3 hours

These values can be changed at any time using the commands below.

How to Use

Rain Limiter is controlled using the /rainlimiter command.

You must have operator permissions or permission level 2 to change the settings.

View Current Settings

Use:

/rainlimiter status

This displays the currently configured rain, thunderstorm, and clear-weather durations.

Change Maximum Rain Length

Use:

/rainlimiter set rain <duration>

Example:

/rainlimiter set rain 5m

This limits normal rain to a maximum of 5 minutes.

Other examples:

/rainlimiter set rain 30s

/rainlimiter set rain 10m

/rainlimiter set rain 1h

Change Maximum Thunderstorm Length

Use:

/rainlimiter set thunder <duration>

Example:

/rainlimiter set thunder 3m

This limits thunderstorms to a maximum of 3 minutes.

Other examples:

/rainlimiter set thunder 1m

/rainlimiter set thunder 10m

/rainlimiter set thunder 30s

Change Minimum Clear-Weather Length

Use:

/rainlimiter set clear <duration>

Example:

/rainlimiter set clear 3h

This forces at least 3 hours of clear weather after rain or a thunderstorm ends before bad weather is allowed again.

Other examples:

/rainlimiter set clear 30m

/rainlimiter set clear 1h

/rainlimiter set clear 6h

Reset to Default Settings

Use:

/rainlimiter reset

This restores the default settings:

• Rain: 5 minutes
• Thunderstorms: 5 minutes
• Clear weather: 3 hours

Supported Duration Formats

Rain Limiter supports:

• s — seconds
• m — minutes
• h — hours

Examples:

30s

5m

3h

Example Setup

For short storms with long periods of clear weather:

/rainlimiter set rain 5m

/rainlimiter set thunder 2m

/rainlimiter set clear 3h

This allows normal Minecraft weather to continue functioning while preventing long or excessively frequent storms.

Installation

1. Install the correct version of NeoForge for Minecraft 1.21.1.

2. Place the Rain Limiter JAR into the server's mods folder.

3. Start or restart the server.

4. Use /rainlimiter status to confirm the current settings.

5. Adjust the timings using the commands above.

Rain Limiter is designed primarily as a server-side utility mod, so players joining the server do not normally need the mod installed on their client.
