Code Examples and Tutorials

Ready to get your hands dirty? Let's look at some code examples and tutorials to help you get started with the NOAA Weather API. These examples will demonstrate how to make requests to the API and parse the data.

Python Example:

import requests
import json

# Replace with your desired location
latitude = 37.7749
longitude = -122.4194  # San Francisco

# Construct the API request URL for current conditions
url = f"https://api.weather.gov/points/{latitude},{longitude}"

try:
    # Send the request and get the response
    response = requests.get(url)
    response.raise_for_status()  # Raise an exception for bad status codes
    
    # Parse the JSON response
    data = response.json()
    
    # Extract the forecast URL from the response
    forecast_url = data['properties']['forecast']
    
    # Get the forecast data
    forecast_response = requests.get(forecast_url)
    forecast_response.raise_for_status()
    forecast_data = forecast_response.json()
    
    # Extract and print the forecast
    forecast_periods = forecast_data['properties']['periods']
    for period in forecast_periods:
        print(f"\n{period['name']}:")
        print(f"  {period['shortForecast']}")
        print(f"  Temperature: {period['temperature']} {period['temperatureUnit']}")

except requests.exceptions.RequestException as e:
    print(f"An error occurred: {e}")
except (KeyError, IndexError) as e:
    print(f"Error parsing the JSON response: {e}")
except Exception as e:
    print(f"An unexpected error occurred: {e}")

This Python code snippet retrieves the current weather forecast for a specified location. It uses the requests library to make an API call to get the forecast data, and then parses the JSON response to extract and print the forecast details. The code includes error handling to manage potential issues such as network problems or invalid data. The use of clear variable names and comments makes the code easy to understand and adapt for different locations.

JavaScript Example:

// Replace with your desired location
const latitude = 37.7749;
const longitude = -122.4194; // San Francisco

// Construct the API request URL for current conditions
const url = `https://api.weather.gov/points/${latitude},${longitude}`;

fetch(url)
    .then(response => {
        if (!response.ok) {
            throw new Error(`HTTP error! status: ${response.status}`);
        }
        return response.json();
    })
    .then(data => {
        const forecastUrl = data.properties.forecast;
        return fetch(forecastUrl);
    })
    .then(response => {
        if (!response.ok) {
            throw new Error(`HTTP error! status: ${response.status}`);
        }
        return response.json();
    })
    .then(forecastData => {
        const forecastPeriods = forecastData.properties.periods;
        forecastPeriods.forEach(period => {
            console.log(`\n${period.name}:`);
            console.log(`  ${period.shortForecast}`);
            console.log(`  Temperature: ${period.temperature} ${period.temperatureUnit}`);
        });
    })
    .catch(error => {
        console.error('There was an error:', error);
    });

This JavaScript code achieves the same result, but uses the fetch API to retrieve and parse weather data. It first gets the forecast URL, then retrieves the forecast data, extracting the necessary information. It also includes error handling using try...catch blocks to manage any issues with the API requests or data parsing. This example demonstrates how to use the NOAA Weather API to get weather data for a specific location in a JavaScript environment, which is frequently used for web applications. These code examples provide a solid foundation for getting started with the NOAA Weather API. Experiment with different parameters, endpoints, and programming languages to build your own weather applications. Remember to always consult the API documentation for the most up-to-date information and best practices.
