Weather Skill

Provides weather information for locations around the world using the free Open-Meteo API.

When to Use

• User asks about current weather
• User asks about temperature
• User asks about weather forecasts
• User mentions weather-related queries

Available Operations

1. Get Current Weather: Retrieve current conditions for a location 2. Format Weather Data: Present weather in a user-friendly format

Instructions

When a user asks about weather:

1. Identify the location from the user's query 2. Look up the latitude and longitude for that location (common cities below) 3. Use the Open-Meteo API to get weather data 4. Present the weather information in a friendly format

Common City Coordinates

Weather Code Meanings

Resources

ALWAYS read this documentation before making an API request so you have the right parameters:

• references/api_reference.md - Complete Open-Meteo API documentation

Examples

Example 1: Simple Query

User asks: "What's the weather in New York?" Response: Use coordinates (40.71, -74.01), call Open-Meteo API, format response with temperature and conditions.

Example 2: Temperature Query

User asks: "How hot is it in Miami?" Response: Use coordinates (25.76, -80.19), get temperature_2m, convert to Fahrenheit if needed.

Notes

• Open-Meteo is free and requires NO API key
• Temperature is in Celsius by default (add temperature_unit=fahrenheit for F)
• All times are in the specified timezone

Tips

1. Always include timezone for accurate local times 2. Use temperature_unit=fahrenheit for US users 3. Combine multiple variables in one request to reduce API calls 4. Cache responses when possible (weather updates every 15 minutes)
