DayZ Weather Editor (cfgweather.xml)
Set up your DayZ server's weather without touching raw XML: pick a preset like always sunny or rare light rain, fine-tune clouds, rain, snow, fog, wind and thunderstorms with sliders, watch the animated sky preview react — and download a ready-to-use cfgweather.xml for Chernarus, Livonia or Sakhal.
No issues found — the configuration looks plausible.
Tip: values above about 20 % are already very dense; 50 % and more is horror-movie visibility.
Server path: mpmissions/dayzOffline.chernarusplus/cfgweather.xml · Stop the server before uploading; changes apply after a restart.

Ready-made presets: always sunny, rare light rain, changeable, permanent storm, dense fog and more — adapted to each map (snow instead of rain on Sakhal).
See it before your players do: an animated sky scene plus a simulated 4-hour weather timeline show what your values actually mean in game.
Safe output: plausibility checks catch impossible settings, and the export matches the official file format including its comments.
How it works
Choose your map and a preset as a starting point. The simple mode covers everything most servers need: cloud range, rain or snow amount, fog, wind and thunderstorms — all as sliders with live feedback.
The pro mode exposes every raw value of cfgweather.xml (current, limits, timelimits, changelimits, thresholds and storm) with plain-language explanations, so you can tune transition speeds and windows exactly.
Download cfgweather.xml and upload it into mpmissions/<your mission>/ while the server is stopped, then restart. The editor exports reset="1" enable="1" so the file actually takes effect.
Frequently asked questions
Where does cfgweather.xml go on my DayZ server?
Into your mission folder: mpmissions/dayzOffline.chernarusplus/ for Chernarus, mpmissions/dayzOffline.enoch/ for Livonia and mpmissions/dayzOffline.sakhal/ for Sakhal. Stop the server before replacing the file and restart afterwards — weather changes only apply after a restart.
Why does my cfgweather.xml have no effect?
The vanilla file ships with enable="0", which switches it off completely — the server then uses its scripted default weather. Set enable="1" and also reset="1", otherwise weather stored in the mission storage can override your start values. This editor exports both flags enabled by default.
How do I get weather that is always sunny?
Use the always-sunny preset: it pins overcast, fog and precipitation to 0, keeps wind gentle and makes lightning impossible (storm threshold above 1.0). This limits-with-min-equal-max pattern is exactly how the community locks weather permanently.
How do I set up rare, light rain?
Use the rare-light-rain preset: rain intensity is capped around 35 %, and rain only becomes possible when cloud cover is high (thresholds min around 0.65) while the allowed cloud range mostly stays below that. Long timelimits keep the weather calm between showers.
Does snowfall work on Chernarus or Livonia?
No — snowfall is a feature of winter maps like Sakhal. The vanilla files explicitly keep snowfall at 0 on Chernarus and Livonia, and rain at 0 on Sakhal. The editor switches the precipitation channel automatically depending on the selected map and warns you if a config mixes them up.
