Getting Started With Meteomatics Weather API

Meteomatics provides a REST¹-style API to retrieve historic, current, and forecast data globally. This includes model data and observational data in time series and areal formats. Areal formats are also offered through a WMS²/WFS³-compatible interface. Geographic and time series data can be combined in certain file formats, such as NetCDF.

How Does It Work?

The URL for an API query has the following structure:

api.meteomatics.com/validdatetime/parameters/locations/format?optionals

Your First Query

After you receive your login username and password you can immediately start using and exploring the Weather API.
By clicking on the following example link, for the current air temperature in Berlin, you will be prompted to enter your login details.

https://api.meteomatics.com/__replace__0T00:00:00Z/t_2m:C/52.520551,13.461804/html

You can also use our URL creator tool which will guide you through the step by step process.
Looking at the example from above:

api.meteomatics.com/__replace__0T00:00:00Z/t_2m:C/52.520551,13.461804/html

• __replace__0T00:00:00Z - current date and time (Z is the time zone designator for UTC time)
• t_2m:C - parameter with units (temperature at two meters above ground in degrees Celsius)
• 52.520551,13.461804 - latitude, longitude (in decimal degrees)
• html - output format

Use a Time Interval

Let’s get the temperature for a ten day interval with temporal increments of one day:

api.meteomatics.com/__replace__0T00:00:00Z--__replace__3T00:00:00Z:PT1H/t_2m:C/52.520551,13.461804/html

• start date: __replace__0T00:00:00Z
• end date: __replace__3T00:00:00Z
• time step: PT1H - time step (1 hour)

Let's Add More Parameters

For more than one parameter type them separated by commas:

api.meteomatics.com/__replace__0T00:00:00Z--__replace__3T00:00:00Z:PT1H/t_2m:C,precip_1h:mm,wind_speed_10m:ms/52.520551,13.461804/html

• t_2m:C - temperature at two meters in degree Celsius
• precip_1h:mm - precipitation during the last hour in mm
• wind_speed_10m:ms - wind speed at 10 m in m/s

Get Parameters On a Grid

Interested in a specific area? No problem, just adapt the coordinates. For example, let’s get the coordinates of a rectangle with a fixed resolution:

api.meteomatics.com/__replace__0T00:00:00Z/t_2m:C/50,10_40,20:0.02,0.04/html

• 50,10 - latitude max, longitude min (upper left corner of the rectangle)
• 40,20 - latitude min, longitude max (lower right corner of the rectangle)
• 0.02,0.04 - resolution (latitude direction: 0.02°, longitude direction: 0.04°)
• html - output format (png or csv also possible)

Output Formats

You can change the output format to your desired format. Just replace html in the query above:

png, xml, JSON, netcdf...

api.meteomatics.com/__replace__0T00:00:00Z--__replace__3T00:00:00Z:PT1H/t_2m:C/52.520551,13.461804/json

• json - json format
