Weather

Use the most reliable location match first. For Chinese city names or other non-Latin input, prefer wttr.in with the original query because it resolves native names directly. Use Open-Meteo for structured current conditions and forecasts only after you have confirmed the exact city.

Accuracy Rules

  • Always restate the matched location, region/country, and observation time in the final answer.
  • Do not trust the first geocoding hit blindly. Check country, admin1, admin2, and population.
  • For Chinese city queries, do not send Hanzi directly to Open-Meteo geocoding unless the top result is obviously correct. Prefer wttr.in with the original Chinese name, or geocode the English/pinyin city name instead.
  • If multiple plausible matches remain, ask a follow-up question or state the assumption clearly.
  • Use timezone=auto when calling Open-Meteo so the reported time matches the location.

wttr.in (best for direct city-name queries)

Quick current conditions:

bash
curl -s "https://wttr.in/London?format=%l:+%c+%t+%h+%w"

Chinese city example:

bash
curl -s "https://wttr.in/%E6%88%90%E9%83%BD?format=%l:+%c+%t+%h+%w"
curl -s "https://wttr.in/%E4%B8%8A%E6%B5%B7?format=%l:+%c+%t+%h+%w"

JSON output if you need more detail:

bash
curl -s "https://wttr.in/Chengdu?format=j1"

Tips:

  • URL-encode spaces: New York -> New+York
  • URL-encode non-ASCII text before sending the request
  • Use ?m for metric units and ?u for US units

Open-Meteo (best for structured forecasts)

  1. Geocode the city and verify the returned location metadata:
bash
curl -s "https://geocoding-api.open-meteo.com/v1/search?name=Chengdu&count=3&language=en&format=json"
  1. Query current weather and today's forecast with the verified coordinates:
bash
curl -s "https://api.open-meteo.com/v1/forecast?latitude=30.66667&longitude=104.06667&current=temperature_2m,relative_humidity_2m,weather_code,wind_speed_10m&daily=weather_code,temperature_2m_max,temperature_2m_min&forecast_days=1&timezone=auto"

Important:

  • For Chinese inputs like 成都, geocoding name=%E6%88%90%E9%83%BD may return smaller homonym locations first. Prefer Chengdu after verifying it matches Sichuan, China.
  • If geocoding looks suspicious, fall back to wttr.in for the original city name instead of presenting a likely wrong result.
