Install

# With uv (recommended)
uv tool install weathr

# With pipx
pipx install weathr

First-Run Onboarding

On your first launch (or at any time by running weather setup), weather launches an interactive onboarding flow. It detects your location using IP geolocation, asks to confirm your preferred city, and lets you pick your default unit system.

Your preferences are saved locally (config.toml). After setup, simply running weather displays your local forecast instantly.

Usage

# Check current weather + 6-day forecast for your saved location
weather

# Check weather for any city, landmark, address or postal codes
weather -l Tokyo
weather -l "Berlin, Germany"
weather -l 94103

# Specify total days of forecast (1 to 16 days)
weather -d 3
weather -l London -d 10

# Override unit system
weather --metric     # °C, km/h, mm
weather --imperial   # °F, mph, in

# Output JSON for scripting
weather --json
weather -l "Reykjavik" --json | jq .weather.current.temperature

# Verbose logging
weather -l "Berlin" -v

CLI Options & Subcommands

Default File Paths

Cache Management

weather maintains a fast binary msgpack cache to eliminate redundant network calls:

# View cache file location
weather cache path

# Remove expired entries (>1 week old)
weather cache prune

# Wipe the cache entirely
weather cache clear

Configuration Management

# Run interactive setup at any time
weather setup

# Display config file path
weather config path

Config file example (config.toml):

unit_system = "metric"
theme = "default"

[location]
latitude = 37.774929
longitude = -122.419416
display_name = "San Francisco, California, United States"

Optional: OpenWeather API Key

weather works out of the box with zero configuration using Open-Meteo. If you want OpenWeather as an automatic secondary fallback for Air Quality (AQI) data, obtain a free API key and set the OPENWEATHER_API_KEY environment variable:

Linux & macOS (Bash / Zsh)

echo 'export OPENWEATHER_API_KEY="your_api_key_here"' >> ~/.bashrc  # or ~/.zshrc
source ~/.bashrc  # or source ~/.zshrc

Windows (Powershell)

[System.Environment]::SetEnvironmentVariable('OPENWEATHER_API_KEY', 'your_api_key_here', 'User')
