How to Create a Great Weather Dashboard With a Weather API – Part 3 (Weather Forecast)

by | Sep 26, 2023

Accurate weather predictions are helping businesses for many purposes today. Weather forecasting data obtained with weather observations has recently become a very valuable resource. We can see accurate weather forecasts in the weather dashboard of almost every website with high user traffic.

Every weather dashboard with accurate weather forecasts is the most effective step in increasing user satisfaction today. It is also one of the simplest steps. Today, businesses and developers can use many accurate forecast provider services. They can use one of these providers to provide accurate forecasts to their users or analyze these data. This article will discuss the importance of accurate weather forecast data and its use cases. Then, we will develop a stunning, accurate weather forecast dashboard.

What is the Importance of Accurate Weather Forecasts?

Accurate weather forecasts are of great importance in a number of industries and even in our daily lives today. Here are some reasons why accurate weather forecasts are important:

  • Safety: Accurate weather forecasts can directly help keep people and property safe by predicting dangerous weather conditions such as natural disasters. For example, knowing about a rapidly approaching storm or hurricane can help the public take early action, minimizing potentially dangerous situations.
  • Transportation and Travel: Weather forecasts are one of the primary factors influencing trip planning. Accurate forecasts can help travelers plan their flights or road trips and make necessary adjustments based on that data.
  • Agriculture: The agricultural sector is one of the fields of activity that is greatly affected by weather conditions. Accurate weather forecasts can provide farmers with information on which crops to plant or harvest.
  • News and Media: Weather forecasts are information that is often presented in the news. Accurate forecasts keep the public informed of possible weather changes and conditions.
  • Natural Resource Management: Weather forecasting is essential for protecting and managing natural resources such as water management, forest fires, flood control, and environmental management.

Create a Stunning, Accurate Weather forecast Dashboard in a Web App

In this part, we will develop a stunning weather forecast dashboard with HTML, CSS, and JavaScript. The data in this dashboard will be obtained from the weatherstack API.

The weatherstack API is a very powerful weather forecast API that provides highly accurate weather forecast data for the next 14 days from today for millions of locations. It is the most accurate forecast provider in the market. This API can provide the weather forecast both hourly and daily. It is actively used by 75,000 companies today. Many weather apps get weather data from the weatherstack API.

In addition, this API provides its users with unique documentation. With this documentation, developers and businesses can easily have a lot of information about the API, such as API authentication, HTTPS encryption, and API error codes. Finally, its documentation provides sample integration codes for programming languages such as PHP, Python, and Node.js.

Before we integrate the weatherstack API into the web application and start using it, let’s sign up for one of the ‘Professional’ or ‘Business’ subscription plans and get an API key.

After obtaining the API key, let’s open an HTML file in the file path where we will develop the application and put the following codes in this file:

            tempetureDiv.textContent = `${avgTemp}°C`;

      .catch(error => {
        console.error("Error fetching data:", error);

With this application, we created a weather dashboard using the future 4-day weather forecast data and current weather data of the New York location. Before running the application, let’s put our own API key in the ‘YOUR-API-KEY’ field and run the application.

The weather forecast dashboard we see after running the application is as follows:
