Weather

You can check weather for any location worldwide. No API key needed.

Current weather

# Quick one-line weather
curl -s "wttr.in/CITY?format=3"

# Detailed current conditions
curl -s "wttr.in/CITY?format=%l:+%c+%t+(feels+like+%f)+💧%h+💨%w"

# Full forecast (3 days, colored terminal output)
curl -s "wttr.in/CITY?lang=pt"

# Compact forecast
curl -s "wttr.in/CITY?format=v2&lang=pt"

JSON format (for structured data)

# Full weather data as JSON
curl -s "wttr.in/CITY?format=j1" | jq '{
  location: .nearest_area[0].areaName[0].value,
  country: .nearest_area[0].country[0].value,
  temp_c: .current_condition[0].temp_C,
  feels_like_c: .current_condition[0].FeelsLikeC,
  humidity: .current_condition[0].humidity,
  description: .current_condition[0].weatherDesc[0].value,
  wind_kmph: .current_condition[0].windspeedKmph,
  wind_dir: .current_condition[0].winddir16Point,
  visibility_km: .current_condition[0].visibility,
  uv_index: .current_condition[0].uvIndex
}'

# 3-day forecast
curl -s "wttr.in/CITY?format=j1" | jq '.weather[] | {
  date: .date,
  max_c: .maxtempC,
  min_c: .mintempC,
  avg_c: .avgtempC,
  sun_hours: .sunHour,
  description: .hourly[4].weatherDesc[0].value
}'

Moon phase

curl -s "wttr.in/Moon"
curl -s "wttr.in/Moon?format=j1" | jq '.weather[0].astronomy[0]'

Open-Meteo API (alternative, more precise)

# Current weather by coordinates (no API key needed)
curl -s "https://api.open-meteo.com/v1/forecast?latitude=LAT&longitude=LON&current=temperature_2m,relative_humidity_2m,wind_speed_10m,weather_code" | jq '.current'

# 7-day forecast
curl -s "https://api.open-meteo.com/v1/forecast?latitude=LAT&longitude=LON&daily=temperature_2m_max,temperature_2m_min,precipitation_sum,weather_code&timezone=auto" | jq '.daily'

# Get coordinates from city name (geocoding)
curl -s "https://geocoding-api.open-meteo.com/v1/search?name=CITY&count=1" | jq '.results[0] | {name, latitude, longitude, country}'

Tips

• Replace CITY with the city name. Use + for spaces: New+York.
• Use lang=pt for Portuguese, lang=en for English.
• wttr.in accepts airport codes (GRU, JFK), coordinates (48.8,2.3), and city names.
• The user's timezone and location may be in USER.md — use them as defaults.
• If the user doesn't specify a location, ask or use their default.
• Open-Meteo is better for precise forecasts and historical data.
