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/stations/normals

Parameters

Just add the station’s ID through the station parameter. Please note that not all weather stations provide climate normals for all periods.

Parameter	Description	Type	Required	Default
station	The weather station ID	String	Yes	undefined
start	The start year (YYYY) of the period	String	No	null
end	The end year (YYYY) of the period	String	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
month	The integer number of the month (1 to 12)	Integer
tavg	The mean temperature in °C	Float
tmin	The average minimum temperature in °C	Float
tmax	The average maximum temperature in °C	Float
prcp	The average total precipitation in mm	Integer
pres	The average sea-level air pressure in hPa	Float
tsun	The average sunshine duration in minutes	Integer

More information about the data format is available here.

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/stations/normals?station=10637&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 response should look like that:
