Weather Union provides powerful APIs for integrating live weather data into your applications. With a wide range of endpoints, you can access current weather data at specific locations. This guide will walk you through the various APIs offered by Weather Union and provide examples of how to use them in Python.

What is Weather Union & Its Features

Weather Union is a comprehensive weather data provider that offers a variety of APIs to access live weather information. Some key features include:

• Current weather data at specific locations
• Weather forecasts for multiple days
• Historical weather data
• Global coverage with precise data
• Easy integration with different platforms using simple HTTP requests

Limitation: Currently available across 45 large cities, these weather stations will expand in other Indian cities “very soon”. You can see on the website for available cities.

Weather Union API with Python

This section covers how to use the Weather Union APIs in Python. We’ll start with fetching current weather data using latitude and longitude and then show examples with different locations.

Note: You can get the latitude and longitude of any available city by search on google.

Example 1: Current Weather Data at a Latitude and Longitude

This API allows you to fetch current weather data at a given latitude and longitude within a 2 km radius of Weather Union’s weather device. The response includes information such as temperature, humidity, wind speed, and more.

Request:

GET /get_weather_data?latitude=28.555596&longitude=77.345713
Headers:
- x-zomato-api-key: your-api-key

Example Response:

{
  "status": 200,
  "message": "Successful response fetched",
  "device_type": 1,
  "locality_weather_data": {
    "temperature": 25,
    "humidity": 50,
    "wind_speed": 5,
    "wind_direction": 180
  }
}

Here’s how you can use Python’s requests library to access the Weather Union APIs:

import requests

url = 'https://weatherunion.com/gw/weather/external/v0/get_weather_data'

# Nigdi, Pune
params = {
    'latitude': 18.6492,
    'longitude': 73.7707
}

headers = {
    'x-zomato-api-key': 'fade2f8ba0d62fd74e9156f02249e448'
}

response = requests.get(url, params=params, headers=headers)

if response.status_code == 200:
    weather_data = response.json()
    print(weather_data)

Output:

Example 2: Current Weather Data for Another Location

Let’s fetch weather data for another set of coordinates to illustrate flexibility.

import requests

api_key = 'generated-api-key'

# Noida, UP
latitude = 28.5355
longitude = 77.3910

url = f'https://www.weatherunion.com/gw/weather/external/v0/get_weather_data?latitude={latitude}&longitude={longitude}'
headers = {
    'x-zomato-api-key': 'fade2f8ba0d62fd74e9156f02249e448'
}

response = requests.get(url, headers=headers)
data = response.json()
print(data)

Output:

Conclusion

Weather Union APIs provide a convenient way to access live weather data for various applications. By integrating these APIs into your projects, you can enhance user experience and make informed decisions based on real-time weather information.
