## current\_weather

`Read-only` · `Reaches outside Vistazo`

Current conditions (temperature, feels-like, humidity, precipitation, wind, sky) for a place — one record, good for a stat card. Give a place name like "Paris" or "Cherry Hill, NJ", or explicit latitude+longitude. Returns a `units` map for labels.

## forecast

`Read-only` · `Reaches outside Vistazo`

Daily weather forecast (sky, high/low/mean temperature, precipitation, max wind) for the next N days — one row per day, good for a line or bar chart. Same columns as historical\_weather, so past + forecast union onto one chart. Returns a `units` map for axis labels.

## historical\_weather

`Read-only` · `Reaches outside Vistazo`

Daily historical weather (sky, high/low/mean temperature, precipitation) for a past date range (ERA5 reanalysis, 1940–present) — one row per day, a time series to chart. Same columns as forecast. Use interval="monthly" to roll long ranges up to one point per month. Returns a `units` map for axis labels.
