# meteostat.Normals
Query climate normals for one or multiple weather stations or a single geographical point.
# Parameters
The loc parameter is required. You can pass one (String) or multiple Meteostat weather station identifiers (Tuple or List), a meteostat.Point or a DataFrame returned by the meteostat.Stations.fetch method.
By default, Meteostat returns data for all available reference periods. If you want to retrieve climate normals for a specific period, please specify a start and end year.
| Parameter | Description | Type | Default |
|---|---|---|---|
| loc | Weather station(s) or Point | DataFrame, Point, String, List or Tuple | undefined |
| start | The first year of the period | Integer | None |
| end | The last year of the period | Integer | None |
# Attributes
Attributes allow the configuration of general settings and behaviour.
| Parameter | Description | Type | Default |
|---|---|---|---|
| cache_dir | The path of the cache directory | String | ~/.meteostat/cache |
| cache_subdir | The subdirectory of the cache | String | Normals |
| autoclean | Remove outdated files automatically from cache | Boolean | True |
| max_age | Maximum age of a cached file in seconds | Integer | 86400 |
| processes | Maximum number of processes used for data processing | Integer | 1 |
| threads | Maximum number of threads used for data processing | Integer | 1 |
You can disable caching completely by setting max_age to 0.
When changing attributes, make sure to do so before creating a class instance:
from meteostat import Normals
Normals.cache_dir = '/my/path/goes/here'
data = Normals('10637')
