Weather Skill

Get current weather and forecasts with Open-Meteo as the primary source and

wttr.in

as a fast human-readable fallback.

When to Use

Use this skill when the user asks things like:

• "What's the weather in Tokyo?"
• "Will it rain today in Cilacap?"
• "Temperature in London right now"
• "Forecast for the next 3-7 days"
• Travel planning with weather context

Do not use this skill for:

• Historical weather data
• Severe weather alerts or emergency warnings
• Aviation or marine weather
• Climate analysis or long-term trends
• Hyper-local sensor-grade measurements

Location

Always ground the request to a real location.

• If the user already gave a city/region/airport code, use it.
• If the follow-up omits the location, reuse the last grounded weather location.
• If no location can be grounded, ask briefly for one instead of guessing.

Open-Meteo (Primary)

Prefer Open-Meteo for current conditions and forecast data because it is structured, keyless, and easy to audit.

wttr.in (Fallback / Quick Readable Output)

Use

wttr.in

when you need a quick readable summary, a simple terminal forecast, or an image output.

Quick Response Rules

• For current weather: prefer Open-Meteo current data.
• For "will it rain?": prefer Open-Meteo hourly precipitation probability.
• For 3-7 day forecast: prefer Open-Meteo daily forecast.
• For quick terminal-friendly summary:

  wttr.in

  is acceptable as fallback.
• If the user asks for a concise answer, summarize the useful fields instead of dumping raw JSON.

Response Templates

Use short, grounded answers in the user's language unless they explicitly ask for a different language. Prefer concrete fields over vague wording.

[Location]: [Condition] [Temperature]
Feels like: [FeelsLike]
Wind: [Wind]
Humidity: [Humidity]

Rain / Next Few Hours

For [Location], rain chance in the next few hours is [Probability].
If relevant, mention the highest nearby precipitation window instead of guessing.

Daily Forecast

[Location] forecast:
- Today: [Condition], [Min]-[Max]
- Tomorrow: [Condition], [Min]-[Max]
- Next: [Condition], [Min]-[Max]

If Location Is Missing

Ask briefly for the city/region instead of guessing.
Example: "Kota atau wilayahnya di mana?"

Notes

• No API key is required.
• Open-Meteo should be treated as the default primary source.

• wttr.in

  is best treated as fallback, quick summary, or image output.
• Do not invent locations.
• For official warnings, use the relevant national meteorological authority instead of this skill alone.
