What is Weather?
The Weather skill provides a seamless way for an AI agent to retrieve real-time meteorological information using high-performance command-line tools. By leveraging free, no-registration services like wttr.in and Open-Meteo, this skill allows users to check atmospheric conditions, humidity, wind speeds, and moon phases for any location worldwide. It is specifically optimized for terminal environments, making it a versatile utility within the Openclaw Skills library.
Whether you need a quick one-line summary of the current temperature or a detailed multi-day forecast, this skill handles the heavy lifting of network requests and data formatting. It serves as a reliable bridge between an AI agent and global weather stations, ensuring that climate data is always just a simple command away.
Weather Use Cases
- Checking local weather conditions before scheduling outdoor tasks or travel.
- Integrating real-time climate data into automated daily briefing scripts or status reports.
- Fetching weather forecasts for specific airport codes or geographic coordinates during research.
- Programmatically accessing JSON weather data for data analysis tasks using Openclaw Skills.
How Weather Works
- The skill identifies the target location via city name, airport code, or latitude/longitude coordinates.
- It initiates a curl request to the primary service (wttr.in) using specialized format codes.
- The service processes the request and returns data in the requested format, such as text, PNG, or JSON.
- If the primary service is unavailable, the skill can fallback to Open-Meteo for programmatic JSON data.
Weather Setup
To use this skill, ensure that curl is installed on your system. No API keys or external authentication are required.
# Verify installation by fetching a quick weather summary
curl -s "wttr.in/London?format=3"
Weather Data Schema & Taxonomy
The skill utilizes specific format codes to organize and display weather metadata. Data can be retrieved in tabular or line formats:
| Attribute | Description | Code |
|---|---|---|
| Location | The specified city, airport, or coordinate name | %l |
| Condition | Current weather status emoji and description | %c |
| Temperature | Current temperature in C or F | %t |
| Humidity | Relative humidity percentage | %h |
| Wind | Wind speed and direction | %w |
| Moon | Current moon phase | %m |
Weather Advanced Features
- Multi-format support including plain text for consoles, JSON for apps, and PNG for visual reports.
- Global unit compatibility with metric (?m) and USCS (?u) system toggles.
- Geographic precision using airport codes (JFK, LHR) or raw coordinates.
- Data filtering to limit output to specific timeframes like "Today only" (?1) or "Current only" (?0).
- Fallback mechanisms for high-reliability data retrieval within Openclaw Skills workflows.
