In Summer, all rains will be thunderstorms. Instead of snowing, it will only rain in snowy biomes, but they won’t defrost. Wheat will also grow 1.5x faster than in any other season, as if absorbing all that yummy heat. When in a desert biome, exposed to the sun, and not wearing protection (leather), you’ll get hurt every so often from dehydration and burns. Summer rain will destroy most of the plants generated from Spring. Just like the Spring, it will defrost the ice/snow generated from Winter in non-snowy biomes. Finally, days are longer and nights are shorter(disabled).
Grass and Leaves have a modified color. Red and yellow flower textures change to accompany the color of the grass in Autumn. You’ll also get bonus wheat while harvesting.
It’s always snowing in Winter, except in the Desert. In already cold biomes such as Tundras, Taigas, and Ice Deserts, the temperature drops even further, and can cause frostbite and slow you down, unless you have on protection (full leather armor). Lastly, days are shorter and nights are longer(disabled).
Tall grass and plants (even custom plants, if added to the config) will grow on grass blocks affected by direct sunlight.
