FMI-Opendata-Python

A minimal Python library to pull basic weather data from the FMI open data service.

Motivation

I wanted a simple way to pull the temperature, pressure etc. data from selected cities. Could not find a suitable solution so I decided to write my own :)

Prerequisites

Get a personal API key from FMI to gain access to the FMI open data.

Example uses

Get the latest temperature from Helsinki

import fmiopendata

fmiod = fmiopendata.FMIOpenData()
fmidata = fmiod.get_data("Helsinki", "temperature")

Get the temperature, pressure and visibility from Espoo with given start time

import fmiopendata

fmiod = fmiopendata.FMIOpenData()
fmidata = fmiod.get_data("Espoo", "temperature,pressure,visibility", "2017-08-29T07:00:00Z")

Using the output

The data is currently returned as a list of custom objects (NamedTimeSeries). To print the data on the console:

for d in fmidata:
    print d.name, 'at', location
    for t, val in zip(d.t, d.data):
        print t.strftime("%Y-%m-%d %H:%M:%S"), val
