World Weather and Climate

🌍 World Weather and Climate Mod

World Weather and Climate Mod (WWCM) brings a persistent calendar, dynamic climate, seasonal conditions, and meaningful weather effects to Minecraft 1.20.1.

Instead of treating weather and seasons as purely visual systems, WWCM turns them into a living part of your world. Track the current date, season, climate, humidity, soil fertility, weather conditions, and special events through an elegant in-game HUD or the interactive Calendar item.

WWCM can work completely standalone or integrate with Serene Seasons when installed.

✨ Features

📅 A Complete World Calendar

WWCM adds a persistent calendar system to your Minecraft world. The calendar automatically progresses as the world advances and keeps track of:

The length of a year is configurable, with 365 days by default. The calendar is managed by the server and synchronized with all connected players.

📆 Seasonal Phases

Every season is divided into three phases: Early, Mid, and Late. This allows the climate to gradually change throughout the year instead of simply switching from one season to another.

🌦️ Dynamic Climate

The climate of your world changes throughout the year according to the current month and season. WWCM deliberately avoids exposing raw numerical climate values. Instead, the player receives clear qualitative information.

🌡️ Temperature

💧 Humidity

🌱 Soil Fertility

This makes climate information immediately understandable without requiring the player to interpret temperatures, percentages, or other numerical values.

☀️ Seasonal Climate Conditions

Certain periods of the year can produce active climate conditions that directly affect the world.

🏜️ Droughts

Droughts can occur during specific climatic periods and have three levels: Drought, Moderate Drought, and Severe Drought.

During a drought:

🌧️ Rainy Periods

Rainy periods also have three levels: Humid Period, Heavy Rain Period, and Extreme Rain Period.

During rainy periods, WWCM can force and intensify actual rainfall in the world. Extreme rainy periods may also produce thunderstorms. All of these effects can be individually configured.

🌱 Climate Affects Gameplay

Climate isn't just information on a screen. WWCM connects environmental conditions to actual gameplay systems.

Soil Fertility → Crop Growth

Soil fertility directly influences crop growth. Fertile conditions accelerate crop growth, normal conditions provide normal growth, and infertile conditions slow crop growth.

Drought → Farmland

Drought conditions affect farmland moisture. During droughts, farmland loses moisture more quickly and is prevented from being naturally rehydrated by rainfall or nearby water.

Rainy Periods → Actual Weather

Rainy periods influence the actual weather of the world. Depending on the current conditions, WWCM can increase rainfall, force rainfall, intensify rainy periods, or trigger thunderstorms during extreme conditions.

These gameplay effects can be enabled or disabled independently.

🌎 Hemisphere System

WWCM supports both hemispheres. You can configure your world as:

Seasonal climate patterns are automatically inverted between hemispheres. This allows the same calendar system to represent different seasonal cycles. The selected hemisphere is stored persistently in the world.

🌿 Serene Seasons Integration

WWCM is designed to work alongside Serene Seasons. When Serene Seasons is installed, WWCM automatically integrates its calendar and seasonal systems.

With Serene Seasons installed:

Without Serene Seasons:

WWCM uses its own built-in seasonal system. Serene Seasons is completely optional. You can use WWCM as a standalone calendar and climate system without requiring another seasonal mod.

🖥️ Climate HUD

WWCM includes a fully configurable in-game HUD. The HUD provides a quick overview of the current state of the world without requiring the player to open a menu. It can display:

The HUD uses colors and visual hierarchy to make important information immediately readable.

⚙️ HUD Configuration

Press F8 to open the HUD configuration screen. You can:

The HUD supports 6 different positions: Top Left, Top Center, Top Right, Bottom Left, Bottom Center, and Bottom Right. It can also be completely disabled if you prefer a cleaner interface.

🗓️ The Calendar Item

WWCM adds a dedicated Calendar item to the Creative inventory. Right-click the Calendar to open a complete calendar interface.

The GUI displays:

📆 Calendar

🌦️ Climate Panel

The Calendar item also features dynamic artwork. When Serene Seasons is installed, the Calendar uses the corresponding official monthly artwork, providing 12 different visual variations throughout the year.

🎉 Events & Special Dates

WWCM includes a built-in event system for special dates. The calendar automatically recognizes:

Date | Event

January 1 | New Year's Day

March 15 | Harvest Day

Easter | Easter

June 21 | Winter Solstice

September 4 | Fish Day

September 21 | Peace Day

October 31 | Halloween

December 21 | Summer Solstice

December 25 | Christmas

Easter is calculated dynamically using the Gregorian Easter algorithm rather than being assigned to a fixed date.

🎊 Custom Events

Server administrators can create their own commemorative dates. This can be used for:

Custom events are stored persistently in the world and appear automatically on the calendar when their date arrives.

⌨️ Commands

WWCM provides the /calendar command family:

/calendar

Displays current year, date, season, day of the year, day of the week, and events of the day.

/calendar set

Changes the world's current date. Synchronizes with Serene Seasons automatically if installed.

/calendar add

Advances the calendar by the specified number of days.

/calendar reload

Reloads the WWCM configuration without restarting the server.

/calendar dates make

Creates a custom commemorative date.

/calendar dates list

Lists all custom dates currently registered in the world.

/calendar climate

Displays the current season and active climate conditions.

/calendar hemisphere set south

Sets the world to the Southern Hemisphere.

/calendar hemisphere set north

Sets the world to the Northern Hemisphere.

/calendar hemisphere

Displays the currently configured hemisphere.

⚙️ Configuration

WWCM generates the configuration file at:

config/wwcm-common.toml

The configuration is divided into four main sections:

[calendar]

Controls starting year, day, month, year duration, leap-year behavior, and default hemisphere.

[hud]

Controls HUD state (enabled/disabled), display format, position, and scale.

[climate]

Controls the dynamic climate system, seasonal variations, droughts, rainy periods, and fertility cycles.

[effects]

Controls gameplay effects like farmland drying during droughts, crop growth based on fertility, and weather/rain parameters.

🎮 Multiplayer & Server Support

WWCM is built natively for multiplayer environments. The calendar and climate state are managed by the server and synchronized with connected clients.

All players share the exact same:

Supported environments: Dedicated servers, LAN multiplayer worlds, and single-player worlds.

🔧 Technical Compatibility

Minecraft Version: 1.20.1

Mod Loader: Forge 1.20.1

Forge Version: 47.x+

Serene Seasons: 1.20.1 (Optional)

WWCM works independently as a complete solution, but enhances its presentation when paired with Serene Seasons.
