OpenMeteo Weather (openmeteo-sh)
Current weather and forecasts (up to 16 days) via openmeteo CLI. No API key required.
Quick reference
openmeteo weather --current --city=Berlin --llm
openmeteo weather --current --forecast-days=2 --city=London --llm
openmeteo weather --forecast-days=7 --forecast-since=5 --city=Rome --llm
openmeteo weather --current --lat=48.85 --lon=2.35 --llm
Location (pick one)
--city=NAME — city name (auto-geocoded)--city=NAME --country=CODE — disambiguate (e.g. Portland --country=US)--lat=NUM --lon=NUM — direct coordinates
Options
--current — current conditions--forecast-days=N — forecast length, 1–16 (default 7)--forecast-since=N — start from day N (1=today, 2=tomorrow). Must be <= forecast-days.--hourly-params=LIST — override hourly variables (comma-separated)--daily-params=LIST — override daily variables (comma-separated)--current-params=LIST — override current variables (comma-separated)--temperature-unit=UNIT — celsius (default) / fahrenheit--llm — always pass this
Variables
Defaults are sensible for general weather. Override only when needed.
Current & hourly:
temperature_2m — air temp, Capparent_temperature — feels-like, Cprecipitation — rain+showers+snow, mmprecipitation_probability (hourly only) — chance of precipitation, %weather_code — condition, auto-resolved to textwind_speed_10m — wind, km/hwind_gusts_10m — gusts, km/hcloud_cover — cloud cover, %snowfall — snowfall, cmuv_index (hourly only) — UV index
Daily:
temperature_2m_max / temperature_2m_min — max/min temp, Cprecipitation_sum — total precipitation, mmprecipitation_probability_max — max precipitation chance, %weather_code — dominant conditionwind_speed_10m_max — max wind, km/hsunrise / sunset — timessnowfall_sum — total snowfall, cm
Rules
- Always pass
--llm.
- Quote all user-provided values in shell commands:
--city="New York", --city="St. Petersburg". Only known-safe tokens (numbers, single ASCII words) may be unquoted.
- Never use
help subcommand or --raw — work only with what's described here.
- No location specified -> use the user's default city/country if known from session context.
- Summarize results naturally — never paste raw output.
- Use
--forecast-days=1 for today, =2 for tomorrow — minimize token waste.
- Use
--forecast-since=N to skip to a specific future day.
- For targeted questions, override params to fetch only what's needed.
- When the user switches cities ("and what about London?"), carry over all params used in prior weather queries this conversation — including any added in follow-ups. The new city gets the union of all previously requested params.
Examples
"What's the weather like?" -> openmeteo weather --current --city=Berlin --llm
Summarize: "Clear, -12C (feels -17C), wind 9 km/h."
"When will the rain stop?" -> openmeteo weather --forecast-days=2 --city=Berlin --hourly-params=precipitation,precipitation_probability,weather_code --llm
Find when precipitation hits ~0. Answer: "Should stop around 14:00."
"Do I need an umbrella?" -> openmeteo weather --forecast-days=1 --city=Berlin --hourly-params=precipitation,precipitation_probability,weather_code --llm
"Yes — 70% chance between 11:00-15:00, up to 2mm."
"Weather this weekend in Rome?" -> openmeteo weather --forecast-days=7 --forecast-since=5 --city=Rome --daily-params=temperature_2m_max,temperature_2m_min,weather_code,precipitation_sum --llm
Present only Sat/Sun: "Saturday: 14/8C, partly cloudy. Sunday: 16/9C, clear."
"Temperature outside?" -> openmeteo weather --current --city=Berlin --current-params=temperature_2m,apparent_temperature --llm
"-5C, feels like -9C."
