Serene Seasons

Overview

Serene Seasons adds a complete four-season cycle to Minecraft's Overworld. Once installed, the world automatically begins cycling through Spring, Summer, Autumn, and Winter, each with its own visual atmosphere, temperature shifts, weather patterns, and crop fertility rules. Temperate biomes experience the classic four seasons, while tropical biomes like Deserts, Jungles, and Savannas cycle between a Wet Season and a Dry Season instead.

The mod adds three craftable items: the Season Clock for tracking the current season, the Season Sensor for Redstone automation, and Greenhouse Glass for year-round farming. Beyond that, everything is automatic. You can browse all items and recipes using the tabs at the top of this page.

A full year lasts 84 in-game days by default (7 days per sub-season, 3 sub-seasons per season, 4 seasons). Each season is divided into three phases: Early, Mid, and Late, creating smooth visual transitions between seasons. The sub-season duration and day length are both configurable.

The Four Temperate Seasons

Temperate biomes (Plains, Forests, Mountains, Taigas, and most standard biomes) experience the classic four-season cycle. Each season shifts biome temperatures, changes Grass and Foliage colors, and alters weather frequency. The visual transitions are gradual, thanks to the three sub-season phases.

Spring

Spring is the first season of the year. Grass and Foliage transition to a blue-green color, and temperatures begin warming up from Winter. Snow left over from Winter starts to melt as the season progresses. Rain is more frequent during Spring, making it a lush and damp season. Spring crops include Potatoes, Carrots, and Nether Wart, among others.

Summer

Summer brings the warmest temperatures. Grass and Foliage take on a yellow-green tint, and Thunderstorms become more common. This is the most productive farming season with the largest crop list, including Melon Seeds, Wheat Seeds, Sugar Cane, Cocoa Beans, and Cactus. New worlds start in Mid-Summer by default.

Autumn

Autumn turns Grass yellowish while Foliage gets a vibrant orange tint, most striking at its Mid-Autumn peak. Temperatures begin dropping, and by Late Autumn, colder biomes may start receiving Snow before Winter officially begins. Autumn crops include Carrots, Pumpkin Seeds, Wheat Seeds, and Beetroot Seeds.

Winter

Winter is the harshest season. Grass and Foliage fade to muted, desaturated tones. Biome temperatures drop significantly, causing Snow to fall in many biomes that never see it in vanilla Minecraft. Rivers and lakes can freeze. Precipitation is more frequent, but Thunderstorms cannot occur during Winter. Only a handful of crops grow naturally: Saplings, Nether Wart, Red Mushrooms, and Brown Mushrooms.

Tropical Seasons

Tropical biomes don't experience the standard four seasons. Instead, they cycle between a Wet Season and a Dry Season, each with three sub-phases. The affected vanilla biomes include Deserts, Jungles, Mesas, Savannas, and Mushroom Islands. Many Biomes O' Plenty, Traverse, and other modded biomes are also configured as tropical by default.

Wet Season

The Wet Season begins at the start of Winter and ends at the start of Summer (in temperate terms). Grass and Foliage turn a lush, vibrant green. During the Mid-Wet Season, rain can fall in tropical biomes that normally never receive precipitation, such as Deserts and Savannas. During the Early and Late phases, weather behaves as it does in vanilla.

Dry Season

The Dry Season begins at the start of Summer and ends at the start of Winter. Grass and Foliage take on a yellowish, sun-baked tint. During the Mid-Dry Season, rain is completely suppressed in all tropical biomes, even those that normally receive it. Only Summer crops are fertile in tropical biomes year-round due to the consistently high temperatures.

Crop Fertility System

Crop fertility is one of the most impactful features of Serene Seasons. Each crop is assigned specific seasons when it can grow. When a crop is in-season, it grows normally and responds to Bone Meal as expected. When a crop is out of season, it will not grow at all by default (configurable to grow slowly instead). Out-of-season crops can optionally be set to break and drop themselves if the crops_break config option is enabled.

You can check which seasons a crop is fertile in by hovering over the seed item in your inventory. The tooltip displays "Fertile Seasons:" followed by a color-coded list: green for Spring, yellow for Summer, gold for Autumn, and aqua for Winter. Crops that grow in all four seasons show "Year-Round" in light purple.

Biomes that are always snowy (with base temperatures below 0.15) restrict crops to only those listed as Winter-growable. This means if you build a base in a Snowy Tundra or Ice Spikes biome, only Saplings, Nether Wart, and Mushrooms will grow without Greenhouse Glass.

Growing Out-of-Season Crops

There are two methods to bypass seasonal crop restrictions. The first is Greenhouse Glass: place it within 7 blocks directly above your crops (the maximum height is configurable). Any crop beneath Greenhouse Glass will grow regardless of the current season. You only need one block of Greenhouse Glass anywhere in the column above the crop. The second method is using vanilla Bees. Bees pollinate crops regardless of season, making them a reliable year-round farming aid without needing to build a Greenhouse structure.

Craftable Items

Serene Seasons adds three craftable objects: the Season Clock, the Season Sensor, and Greenhouse Glass. Each serves a distinct purpose in tracking, automating around, or mitigating the effects of seasonal changes.

Season Clock

The Season Clock is crafted with 4 Nether Quartz surrounding a Redstone Dust in a plus pattern. It works similarly to a vanilla Clock but displays seasonal information instead of time of day. The clock face animates through the year cycle, and hovering over it in your inventory shows the exact current sub-season and day count. It also serves as a crafting ingredient for the Season Sensor.

Season Sensor

The Season Sensor is a Redstone device that emits a signal based on the current season. Craft it with 3 Glass blocks across the top, 2 Nether Quartz flanking a Season Clock in the middle, and 3 Cobblestone Slabs across the bottom. Right-click the placed sensor to cycle which season it detects: Spring, Summer, Autumn, or Winter. When the selected season is active, the sensor emits a Redstone signal in all four horizontal directions. The signal strength scales from 1 at the start of the season to 15 at the end, letting you build circuits that respond to seasonal progression.

Greenhouse Glass

Greenhouse Glass is crafted with 4 Glass blocks, 4 Cyan Dye, and 1 Wood Plank in an alternating pattern. When placed above crops (within 7 blocks by default), it allows out-of-season crops to grow normally. The block is translucent and functions as a building material, so you can create attractive Greenhouse structures. It has a hardness of 0.3 and is mined with a Pickaxe.

Redstone Automation with Seasons

The Season Sensor opens up creative possibilities for Redstone builds. Since the signal strength ramps from 1 to 15 over the course of a season, you can use comparators to trigger specific actions at different points within a season. For example, you could build a system that automatically switches crop farms between seasonal varieties, or activate snow-clearing mechanisms when Winter arrives.

A practical setup is to place four Season Sensors, one for each season, and connect them to different circuits. When Spring activates, one sensor powers a farm section planted with Potatoes and Carrots. When Summer arrives, a different sensor activates a Melon and Wheat farm. This kind of seasonal automation adds genuine depth to farm design.

Biome Compatibility

Serene Seasons classifies biomes into three categories through its biome_info.json configuration file. Standard temperate biomes receive the full four-season cycle. Tropical biomes (Deserts, Jungles, Savannas, Mesas, and many modded equivalents) use the Wet/Dry season cycle. Blacklisted biomes receive no seasonal effects at all.

By default, Mushroom Islands, Oceans, Deep Oceans, and Rivers are blacklisted from seasonal effects. Several modded biomes from Biomes O' Plenty (Mystic Grove, Ominous Woods, Wasteland), Thaumcraft (Magical Forest), and Abyssalcraft (all Darklands variants) are also blacklisted. A few biomes like BOP's Crag, Wasteland, and Volcanic Island have crop growth disabled entirely.

The mod ships with extensive default support for modded biomes. Biomes O' Plenty, Traverse, Conquest, and Climatic Biomes are all pre-configured with appropriate tropical or blacklisted classifications. If you're using a biome mod not on the list, you can add entries to biome_info.json manually.

Configuration

Serene Seasons is highly configurable through several config files. The main seasons.cfg controls timing, weather, visual effects, and dimension settings. The cropfertility config controls all farming-related behavior. The biome_info.json file controls per-biome seasonal behavior.

Timing Settings (seasons.cfg)

Day Duration defaults to 24,000 ticks (one Minecraft day) and can be set from 20 ticks upward. Sub Season Duration defaults to 7 days (range: 1 to max int). The Starting Sub Season for new worlds defaults to 5 (Mid-Summer), with 0 being random and 1-12 mapping to each sub-season from Early Spring through Late Winter.

Weather & Visual Settings

You can independently toggle Snow and Ice generation during Winter, seasonal weather frequency changes, and seasonal color shifts for Grass, Foliage, and Birch trees. All of these are enabled by default. The Whitelisted Dimensions setting controls which dimensions have seasons; by default only dimension 0 (the Overworld) is included.

Crop Fertility Settings

The seasonal_crops toggle enables or disables the entire fertility system. The crops_break option, when enabled, causes out-of-season crops to break and drop themselves rather than simply refusing to grow. The ignore_unlisted_crops option determines whether crops not explicitly listed in any season's fertility list are fertile year-round (true) or in every season except Winter (false). The crop_tooltips option toggles the in-inventory fertility display. The Greenhouse Glass maximum height defaults to 7 blocks.

Each season's crop list is fully customizable. You can add any mod's crop seeds or blocks to the Spring, Summer, Autumn, or Winter arrays. The mod ships with extensive default support for Pam's HarvestCraft, Simple Corn, and GrowthCraft crops.
