An increasing number of developers are interested in creating a weather forecasting app. The first thing they should do is obtain help from a free weather API JSON, like the one offered by weatherstack. With this API, developers can acquire accurate weather data to integrate into their apps. These APIs will also provide real-time information, which is essential in making weather predictions. People search these forecasts to plan for outdoor activities, prepare for severe weather alerts, and understand climate patterns. These APIs pull data from reliable sources like weather stations, satellites, and meteorological organizations. This ensures the information’s accuracy and timeliness. With weatherstack’s API, integrating this data into your app has become a rather easy task. This guide will explore the process of using weatherstack’s API to create a fully functional weather forecasting app.

How to Find a Good Weather API?
Developing a reliable weather forecasting app requires a good-quality weather API. It’s best to begin by exploring APIs from reliable sources like the National Weather Service or Weather Channel. APIs that offer real-time weather information, air quality indexes, and UV indexes are particularly desirable. Many apps, such as Carrot Weather and weatherstack, use these APIs to provide detailed meteorological data and smart forecasts. Make sure that the API supports both Android and iOS devices. This will allow you to reach a much broader audience than if you were focused only on one OS. Additionally, check if the API offers a free app tier or premium subscription for more advanced features. Only a few APIs offer premium features such as lightning detection, live radar, and historical weather data. Therefore by selecting a reliable API, you can improve your app’s accuracy and user experience, making it one of the best weather apps available.
Is It Reliable to Use APIs for Building a Weather Data App?
Using APIs for building a weather data app is highly reliable and advantageous. APIs provide a standardized way to access and retrieve data from external sources, such as weather data providers.
Here are some reasons why using APIs for building a weather data app is reliable:
- Weather APIs, like weatherstack API, connect you to rather reputable weather data providers like Weather Underground and NOAA weather radar.
- Weather conditions can change rapidly, and APIs make sure that your app reflects the latest weather updates. Therefore you can obtain real-time values for temperature, humidity, wind speed, and more.
- APIs provide a consistent format and structure for weather data. This makes it easier for developers to parse and display the information in their app.
- Reputable weather APIs often provide detailed documentation, including guides, tutorials, and support channels.
How to Use Weatherstack?
First, you must sign up for a weatherstack account. If you are a new user, you can select the free option. This option allows you to obtain real-time weather information and up to 250 calls per month. Afterward, you have to generate an API key to make requests.
Weatherstack Endpoints
Depending on your subscription, you can call different weatherstack endpoints to obtain different types of valuable data. Some of the more popular endpoints are given below.

Let’s start building our weather forecast data app through the weatherstack API.
Styling The App
We aim to create a simple app with background changes according to the weather conditions. First of all, we create an index.html file with the following template:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0"> <meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Weather app</title>
<link rel="stylesheet" href="styles.css" />
<!-- Google Fonts -->
<link rel="preconnect" href="https://fonts.gstatic.com">
<link
href="https://fonts.googleapis.com/css2family=Lora:ital,wght@0,700;1,600&display=swap" rel="stylesheet">
</head>
<body>
<div class="container">
<img src="" alt="" srcset="" id="weather-icon">
<div id="location">Unable to Fetch Weather</div>
<div class="desc">No Information Available.</div>
<div class="weather">
<div class="c">Error</div>
<div class="circle"></div>
<div class="f">Error</div>
</div>
<div class="info">
<h4>Sunrise: <span class="sunrise">No Information Available</span></h4>
<h4>Sunset: <span class="sunset">No Information Available</span></h4>
</div>
</div>
<script src="scripts.js"></script>
</body>
</html>We can connect this file to the styles.css file and the js file. Let’s start styling it as under:
* {
margin: 0;
padding: 0;
box-sizing: border-box;
}
body {
font-family: 'Lora', serif;
}
.container {
height: 100vh;
width: 100vw;
display: flex;
align-items: center;
justify-content: center;
flex-direction: column;
background: rgb(251, 242, 133);
background: radial-gradient(
circle,
rgba(251, 242, 133, 0.6334908963585435) 0%,
rgba(224, 196, 91, 0.8407738095238095) 35%,
rgba(230, 224, 113, 1) 100%
);
}
.weather {
display: flex;
align-items: center;
margin: 15px 0;
font-size: 1.5rem;
}
#location {
font-size: 3rem;
font-weight: 800;
font-style: italic;
}
.desc {
font-size: 1.25rem;
text-transform: capitalize;
}
.circle {
background-color: black;
border-radius: 50px;
height: 15px;
width: 15px;
margin: 0 15px;
}
After the styling part, we move to the API to get the weather data.
Getting Weather Data From a Weather API
First, you must subscribe to a weather API like weatherstack and generate an API key. Once you get the API key, you can return to your coding process.
Coding the JavaScript
Create a scripts.js file and add a variable “API” that will help us fetch the API key. We will use the following endpoint in our weather forecasting app.
https://api.weatherstack.com/forecast
? access_key = YOUR_ACCESS_KEY
& query = New York
& forecast_days = 1
& hourly = 1The code inside the JS file should look like this:
// Weatherstack API. Do not share it publicly.
const api = '66869939e0b182ac2d6************'; //Replace with your API
const iconImg = document.getElementById('weather-icon');
const loc = document.querySelector('#location');
const tempC = document.querySelector('.c');
const tempF = document.querySelector('.f');
const desc = document.querySelector('.desc');
const sunriseDOM = document.querySelector('.sunrise');
const sunsetDOM = document.querySelector('.sunset');
window.addEventListener('load', () => {
let long;
let lat;
// Accessing Geolocation of User
if (navigator.geolocation) {
navigator.geolocation.getCurrentPosition((position) => {
// Storing Longitude and Latitude in variables
long = position.coords.longitude;
lat = position.coords.latitude;
const base = `https://api.weatherstack.com/forecast
? access_key = YOUR_ACCESS_KEY
& query = New York
& forecast_days = 1
& hourly = 1`;
// Using fetch to get data
fetch(base)
.then((response) => {
return response.json();
})
.then((data) => {
const { temp } = data.main;
const place = data.name;
const { description, icon } = data.weather[0];
const { sunrise, sunset } = data.sys;
const iconUrl = `https://openweathermap.org/img/wn/${icon}@2x.png`;
const fahrenheit = (temp * 9) / 5 + 32;
// Converting Epoch(Unix) time to GMT
const sunriseGMT = new Date(sunrise * 1000);
const sunsetGMT = new Date(sunset * 1000);
// Interacting with DOM to show data
iconImg.src = iconUrl;
loc.textContent = `${place}`;
desc.textContent = `${description}`;
tempC.textContent = `${temp.toFixed(2)} °C`;
tempF.textContent = `${fahrenheit.toFixed(2)} °F`;
sunriseDOM.textContent = `${sunriseGMT.toLocaleDateString()}, ${sunriseGMT.toLocaleTimeString()}`;
sunsetDOM.textContent = `${sunsetGMT.toLocaleDateString()}, ${sunsetGMT.toLocaleTimeString()}`;
});
});
}
