Weather Data Fetcher

Fetch daily weather (historical and forecast) by location name or coordinates via Open-Meteo. No API key needed. Scripts: fetch_historical.py (historical), fetch_forecast.py (forecast).

When to invoke

Use this skill when the user asks for:

Historical weather data for a location or coordinates
Weather forecast for the next days
Precipitation or evapotranspiration data for garden planning

Location vs coordinates

Provide either:

Location: positional or --location / -l (e.g. "Oslo, Norway") — geocoded via Open-Meteo
Coordinates: --lat and --lon (both required)

Days: --days N — history default 10 (max 30), forecast default 7 (max 15).

`weather_fetch_historical`

Run scripts/fetch_historical.py. Observed weather (Open-Meteo archive API). Default 10 days, max 30 (--days N).

python scripts/fetch_historical.py "Oslo, Norway"
python scripts/fetch_historical.py "Oslo, Norway" --days 20 --format json --kc 1.05
python scripts/fetch_historical.py --location "London, UK" --format csv
python scripts/fetch_historical.py --lat 59.91 --lon 10.75 --days 30

`weather_fetch_forecast`

Run scripts/fetch_forecast.py. Forecast weather. Default 7 days, max 15 (--days N).

python scripts/fetch_forecast.py "Oslo, Norway"
python scripts/fetch_forecast.py "Paris, France" --days 15 --format json --kc 1.0
python scripts/fetch_forecast.py --lat 59.91 --lon 10.75 --days 14 --format csv

Output columns

Column	Description
---	---
`date`	YYYY-MM-DD
`temp`	Mean daily temperature (°C)
`precip`	Total daily precipitation (mm)
`et0_fao`	FAO-56 reference evapotranspiration (mm/day), after `kc`
`evaporation`	Estimated crop evaporation (mm)
`agg_precip`	Cumulative precipitation
`agg_evaporation`	Cumulative evapotranspiration

kc (crop coefficient): multiplier applied to ET₀. Default 1.0.

Technical notes

Historical: Open-Meteo archive API (observation/reanalysis); hourly → daily (temp = mean, precip/ET = sum).
Forecast: Open-Meteo forecast API; same daily aggregation.
Geocoding: location names resolved via Open-Meteo Geocoding API when not using --lat/--lon.

Troubleshooting

Symptom	Fix
---	---
Location not found	Try a simpler string (e.g. `"Oslo"`) or use `--lat` and `--lon`
Provide either location or both --lat and --lon	Give a location (positional or `--location`) or both `--lat` and `--lon`
API failure	Check internet access; retry — Open-Meteo is free and usually reliable
