Where do D&D 3.5 weather rules come from?
The Dungeon Master's Guide gives guidance for climate, season, temperature extremes, wind, and precipitation when you need day-to-day weather during overland travel or downtime.
Weather Generator
Roll daily weather for wilderness travel and downtime using Dungeon Master's Guide climate and season guidance. Set climate, season, and optional supernatural skies, then share a seed to reproduce the same month.
How it works
What does supernatural weather mean here?
Optional rare events replace the normal sky with a fantastical description while keeping the day's temperature and wind. Frequency controls how often those days appear in a generated month.
Can I reproduce the same month of weather?
Yes. Keep the seed, climate, season, and supernatural setting the same. Climate, season, and seed sync to the URL so you can share a link and get the same daily table again.
