Zomato Weather Union: Real-Time Weather Data for 60 Indian Cities via Public API

As extreme weather events become more frequent and unpredictable, nowcasts are becoming more crucial than traditional forecasts, especially with phenomena like urban heat islands. These days, even the best-laid plans can fall apart if weather isn't factored in.

Zomato is offering real-time weather data from 60 Indian cities through a free public API called Weather Union, gathered via a crowd-supported weather infrastructure.

I've extracted the latitude and longitude of the weather stations that Zomato has provided in PDF format and shared the CSV file on GitHub.

About half of these locations use an Automated Weather System, while the rest have Rain Gauge Systems that only track rainfall. 

For stations with rain gauges, the API provides data only on rainfall, and fields like temperature, humidity, and wind speed return null values.

I’ve created a simple code sample using Zomato's public API, which you can check on GitHub. 

The sample also includes an external link that dynamically constructs a URL to fetch color-coded IMD alerts via Thejesh’s API.

I used AI assistants to help create the CSV file and the code sample.

I'll keep updating this write-up with my findings while I continue experimenting with the API.
