Climate Normals

Climate normals are long-term averages of historical weather observations. Usually, these means are calculated over a period of 30 years (“reference period“). However, any other time series of sufficient length can be used to calculate climate normals.

Climate normals represent the typical monthly weather at a given location. The averages can also be used for calculating anomalies of current weather and climate conditions.

Endpoint

Climate normals are provided through this endpoint:

GET https://meteostat.p.rapidapi.com/point/normals

Parameters

In order to query data for any location you’ll need to specify the lat and lon parameters. You will probably also want to add the alt parameter to your request to make the output more precise. If you do not set the alt parameter, Meteostat will detect the elevation using its own elevation model.

Parameter	Description	Type	Required	Default
lat	The latitude of the geographic location	Float	Yes	undefined
lon	The longitude of the geographic location	Float	Yes	undefined
alt	The elevation of the geographic location	Integer	No	null
units	The unit system of the meteorological parameters	String	No	metric

The units parameter takes one of the following values:

• metric (Celsius, Millimeters, Kilometers per hour)
• imperial (Fahrenheit, Inches, Miles per hour)
• scientific (Kelvin, Millimeters, Meters per second)

Response

The data array of the response contains twelve objects (one per month) for every period. Each of these objects includes the following properties. Please note that all units mentioned below refer to the default units setting.

Parameter	Description	Type
start	The first year (YYYY) of the period (if not specified)	Integer
end	The last year (YYYY) of the period (if not specified)	Integer
month	The month	Integer
tavg	The average daily air temperature in °C	Float
tmin	The average daily minimum air temperature in °C	Float
tmax	The average daily maximum air temperature in °C	Float
prcp	The monthly precipitation total in mm	Float
wspd	The average wind speed in km/h	Float
pres	The average sea-level air pressure in hPa	Float
tsun	The monthly sunshine total in minutes (m)	Integer

Example

The following example requires the cURL command-line interface. Alternatively, you can use an API client like Postman.

curl --request GET \
	--url 'https://meteostat.p.rapidapi.com/point/normals?lat=59.9127&lon=10.7461&alt=26&start=1961&end=1990' \
	--header 'x-rapidapi-host: meteostat.p.rapidapi.com' \
	--header 'x-rapidapi-key: {key}'

Please replace {key} with your personal API key.

Data Response

The data output returns one object per month. Have a look at this example:
