ᚠ Salomea — Valheim Forecast

Weather is deterministic in Valheim: it depends only on world time, not the seed. This reads the live clock off the server and computes the rest.

Weather changes every 666 s of world time; a day is 1800 s. Highlighted column is the period in progress. Each cell is the exact weather for that period, not a chance — Valheim's weather is fully determined by world time. Algorithm and biome weights match the game's EnvMan weighted roll, seeded with the weather period through Unity's xorshift128.
