# SwissWeather Get current weather measurements and forecasts from MeteoSwiss, the official Swiss Federal Office of Meteorology and Climatology. ## 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)** ```bash scripts/current_weather_curl.sh --station RAG ``` **Option 2: Python script (requires: pip3 install requests)** ```bash 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 ```bash 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: ```bash 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. ## Available Data ### Current Weather Measurements Updated every 10 minutes from automated stations: - **Temperature** (°C) - Air temperature at 2m height - **Humidity** (%) - Relative humidity - **Wind** - Speed (km/h), direction (°), gust peak - **Precipitation** (mm) - Recent rainfall - **Pressure** (hPa) - Station level, sea level - **Sunshine** (min) - Duration of sunshine - **Radiation** (W/m²) - Global solar radiation - **Dew point** (°C) ### Weather Forecasts Multi-day forecasts by Swiss postal code: - Daily temperature (min/max) - Weather conditions with icons - Precipitation amount and probability - Hourly forecasts (when available) ## 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: ```bash scripts/current_weather.py --station RAG --json scripts/forecast.py 8640 --json ``` ## Advanced Usage ### Multiple Stations Show all current measurements: ```bash scripts/current_weather.py --all ``` ### Find Nearest Station 1. List all stations: `scripts/current_weather.py --list` 2. Identify closest by name/location 3. Use that station code ### Caching Data updates every 10 minutes. Cache responses appropriately: ```bash # 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 ```bash 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. ## Related - **swiss-transport**: Swiss public transport schedules and connections - **weather**: Generic weather service (wttr.in) - use swissweather for Switzerland
