@tungtrinh Hello, we do not show a 14-day forecast on Windy, so there is no 14-day forecast via API either. The 1-hour forecast is only available through Windy Premium and we do not plan to add it to the API.
@tungtrinh@Squshy Hello, we do not offer weather data in an excel sheets or in any form of a report. If you are interested in API, you can try the trial version at https://api.windy.com and generate your API test key.
Windy Premium is a different service than API. Premium, if necessary, can be used in news articles or other media, thus the mention of "Commercial use allowed."
