Minecraft wiki entry for Rain, associated text: Rainfalls darken the world, causing the light from the sun to decrease by 3, bringing it to light level 12 in full daylight. Moonlight, however, is not reduced, and remains at light level 4. The sky itself darkens, even in biomes where it does not rain, and in Java Edition, celestial bodies (the sun, moon, and stars) are no longer visible.[2] In Bedrock Edition, the sun and moon are still visible in biomes with no rain. While flying, rain also decreases visibility on land. The clouds darken from white to a light gray, although clouds themselves do not precipitate. Although the sun is not visible during rain, the glow associated with sunrise and sunset is still visible.
