Swiss-Weather

Get current weather and forecasts from MeteoSwiss (official Swiss weather service). Use when querying Swiss weather data, local measurements from Swiss weather stations, or Swiss-specific forecasts. Provides real-time measurements (temperature, humidity, wind, precipitation, pressure) from 100+ Swiss stations and multi-day forecasts by postal code. Ideal for Swiss locations - more accurate than generic weather services for Switzerland.

Security Scan

The skill is internally consistent with its stated purpose: it fetches public MeteoSwiss CSV/JSON endpoints via included scripts and requires no credentials or special installs beyond the requests library or curl.

Purpose & Capability

Name/description and included scripts align: current_weather.py and current_weather_curl.sh pull the public CSV from data.geo.admin.ch; forecast.py calls a MeteoSwiss app endpoint. No unrelated services, credentials, or binaries are requested.

Instruction Scope

SKILL.md explicitly instructs running the provided scripts and installing requests; the scripts only fetch and parse public weather endpoints and print results. There are no instructions to read arbitrary local files, environment variables, or send data to unknown external endpoints.

Install Mechanism

No install spec (instruction-only); code files are shipped but nothing is downloaded or executed from arbitrary URLs. Dependencies are limited to the requests Python library or curl (already present on most systems).

Credentials

The skill requires no environment variables, credentials, or config paths. All network access is to MeteoSwiss/public data endpoints, which is proportional to the skill's functionality.

Persistence & Privilege

always is false and the skill does not request persistent/system-wide changes. It does not modify other skills or require elevated privileges.

Assessment

This skill appears coherent and low-risk: it fetches public MeteoSwiss data (CSV and an app JSON endpoint) and requires no credentials. Before installing, consider: 1) provenance — the package source/homepage is unknown, so verify you trust the publisher if provenance matters; 2) network access — the scripts make outbound HTTPS requests to meteoschweiz/data.geo.admin.ch and an app endpoint; ensure this is acceptable on your network; 3) dependency — forecast.py and current_weather.py require the requests library (pip3 install requests) or curl for the shell script; 4) the forecast API used is an app endpoint (User-Agent is set to mimic the official app) and is noted as unstable — expect possible breakage and prefer the CSV fallback for reliability. No credentials are requested and there are no signs of data exfiltration or unrelated behavior.

Why Use This

• Official Swiss data: Direct from MeteoSwiss government service
• Real measurements: 100+ automated weather stations across Switzerland
• No API key required: Free public data
• Swiss-optimized: Better coverage and accuracy for Switzerland than generic services
• Comprehensive: Temperature, humidity, wind, precipitation, pressure, sunshine, radiation

Quick Start

Current Weather by Station

Get real-time measurements from a specific Swiss weather station:

Option 1: Shell script (no dependencies)

scripts/current_weather_curl.sh --station RAG

Option 2: Python script (requires: pip3 install requests)

scripts/current_weather.py --station RAG

Example output:

Station: RAG
Time: 2026-01-15 11:40 UTC
Temperature (°C)........................ 8.6
Rel. humidity (%)...................... 56.3
Wind speed (km/h)...................... 6.8
Precipitation (mm)..................... 0.0

Popular stations:

• RAG - Rapperswil (Zurich region)
• BER - Bern
• ZRH - Zurich Airport
• BAS - Basel
• GVE - Geneva
• LUG - Lugano

List All Stations

scripts/current_weather_curl.sh --list
# or
scripts/current_weather.py --list

Returns 100+ Swiss weather stations with codes and last update time.

Forecast by Postal Code

Get multi-day weather forecast:

scripts/forecast.py 8640            # Rapperswil-Jona
scripts/forecast.py 8001 --days 7   # Zurich, 7-day forecast

Note: The forecast API may occasionally be unstable. If it fails, fall back to current weather measurements.

Station Selection

Choose the nearest station to your location:

• Major cities: BER (Bern), ZRH (Zurich), BAS (Basel), GVE (Geneva), LUG (Lugano)
• Zurich region: KLO (Kloten), RAG (Rapperswil), TAE (Tänikon)
• Central: LUZ (Lucerne), ALT (Altdorf), ENG (Engelberg)
• Mountains: SMA (Säntis), JUN (Jungfraujoch), PIL (Pilatus)

Tip: Avoid mountain stations for valley locations due to altitude differences.

See references/api_info.md for complete station list and details.

JSON Output

All scripts support --json flag for programmatic use:

Caching

Data updates every 10 minutes. Cache responses appropriately:

# Cache current weather for 5-10 minutes
# Cache forecasts for 1-2 hours

API Reference

See references/api_info.md for:

• Complete API documentation
• All available data fields
• Weather icon codes
• Warning levels and types
• Alternative data sources
• Technical details

Dependencies

pip3 install requests

Data Source

• Provider: MeteoSwiss (Federal Office of Meteorology and Climatology)
• Authority: Official Swiss government weather service
• Update: Every 10 minutes (current weather)
• Coverage: 100+ automated stations across Switzerland
• URL: https://data.geo.admin.ch / https://www.meteoschweiz.admin.ch

Troubleshooting

Forecast API fails: The MeteoSwiss app API occasionally changes. If forecast.py fails, use current weather measurements instead, or check references/api_info.md for alternative methods.

Station not found: Use --list to see available stations. Station codes are 3-letter abbreviations (case-insensitive).

Missing data: Some stations don't measure all parameters. Look for - or N/A in output.
