weather

# Weather Two free services, no API keys needed. ## wttr.in (primary) Choose one request that matches the user's scope. Do not fetch current conditions separately when a today or forecast request already includes them. Platform notes: - On Windows PowerShell, use `curl.exe`; bare `curl` may resolve to `Invoke-WebRequest`. - On macOS and Linux, use `curl`. Current conditions only: ```bash curl -s "https://wttr.in/London?format=3" # Output: London: ⛅️ +8°C ``` Custom current conditions format: ```bash curl -s "https://wttr.in/London?format=%l:+%c+%t+%h+%w" # Output: London: ⛅️ +8°C 71% ↙5km/h ``` Today's weather, including current conditions (use this single request for questions about today's weather): ```bash curl -s "https://wttr.in/London?1&m" ``` Full forecast: ```bash curl -s "https://wttr.in/London?T&m" ``` On Windows PowerShell, replace `curl` with `curl.exe` in the commands above. Format codes: `%c` condition · `%t` temp · `%h` humidity · `%w` wind · `%l` location · `%m` moon Tips: - URL-encode spaces: `wttr.in/New+York` - Airport codes: `wttr.in/JFK` - Units: `?m` (metric) `?u` (USCS) - Today only: `?1` · Current only: `?0` - PNG (macOS/Linux): `curl -s "https://wttr.in/Berlin.png" -o weather.png` - PNG (Windows PowerShell): `curl.exe -s "https://wttr.in/Berlin.png" -o weather.png` ## Open-Meteo (fallback, JSON) Free, no key, good for programmatic use: ```bash curl -s "https://api.open-meteo.com/v1/forecast?latitude=51.5&longitude=-0.12&current_weather=true" ``` Find coordinates for a city, then query. Returns JSON with temp, windspeed, weathercode. Docs: https://open-meteo.com/en/docs
