Apprendre Accessing Weather Data | Exploring Public Data APIs

The Open-Meteo API is a free and easy-to-use service that allows you to access weather forecasts and current weather data without needing to register or obtain an API key. You can retrieve weather data by simply specifying the geographic coordinates (latitude and longitude) of your location. This makes the API ideal for quick experiments and learning how to work with real-world weather data in Python.


              12345678910111213141516171819
            
import requests

# Set the coordinates for New York City
latitude = 40.7128
longitude = -74.0060

# Prepare the API endpoint and parameters
url = "https://api.open-meteo.com/v1/forecast"
params = {
    "latitude": latitude,
    "longitude": longitude,
    "current_weather": True
}

# Make the GET request to the Open-Meteo API
response = requests.get(url, params=params)

# Print the JSON response
print(response.json())

In the code above, you use three key parameters to request weather data from the Open-Meteo API:

Latitude: specifies the north-south position of your location;
Longitude: specifies the east-west position of your location;
Current_weather: set to True to request the current weather data for the given coordinates.

These parameters allow you to pinpoint any location on the globe and retrieve up-to-date weather information for that spot.

import requests

latitude = 40.7128
longitude = -74.0060

url = "https://api.open-meteo.com/v1/forecast"
params = {
    "latitude": latitude,
    "longitude": longitude,
    "current_weather": True
}

response = requests.get(url, params=params)
data = response.json()

# Extract temperature and wind speed from the current weather data
temperature = data["current_weather"]["temperature"]
wind_speed = data["current_weather"]["windspeed"]

print("Temperature:", temperature, "°C")
print("Wind speed:", wind_speed, "km/h")

When interpreting weather data fields from the API response, it is important to pay attention to the units. For example, temperature is provided in degrees Celsius (°C), while wind speed is given in kilometers per hour (km/h). Understanding these units ensures that you can present and analyze the weather data correctly. Other fields, such as wind direction, are typically expressed in degrees, where 0° means north, 90° is east, 180° is south, and 270° is west.

2. What type of data structure does `response.json()` return in Python?
