OpenWeatherMap API vs Wunderground API?

Question

I don't see a lot of information available comparing the weather APIs that are available. What is the difference between OpenWeatherMap and Wunderground. I see that the paid version of Wunderground has some higher tiers with more features, but OpenWeatherMap's free tier allows a huge number of uses.

Are there implementation tradeoffs that aren't obvious?

Answer 1

I made small python script for WorldWeatherOnline historical weather data for my personal project. The result can be saved in pandas dataframe and csv files.

Install the package:

pip install wwo-hist

Import package

from wwo_hist import retrieve_hist_data
import pandas as pd  

Example code

frequency=3
start_date = '11-DEC-2018'
end_date = '11-MAR-2019'
api_key = 'YOUR_API_KEY'
location_list = ['singapore','california']

hist_weather_data = retrieve_hist_data(api_key,
                                location_list,
                                start_date,
                                end_date,
                                frequency,
                                location_label = False,
                                export_csv = True,
                                store_df = True)
