The Best Weather APIs for 2024

TL;DR:

  • Weather APIs provide developers access to current, forecasted, and historical weather data.
  • The best weather APIs for 2024 are judged based on functionality & scope, compatibility & ease of implementation, responsiveness & reliability, and cost.
  • The top weather APIs in 2024 include Tomorrow.io, OpenWeatherMap, MeteoGroup, Weatherstack, Weatherbit, Weather2020, AerisWeather, Accuweather, and Visual Crossing.
  • The all-around best Weather API for 2024 is Tomorrow.io’s Weather API, offering 80+ data layers and a top-rated interface.

Accurate, actionable weather forecasts are vital to the success of many organizations.

In fact, there are entire industries where weather conditions directly impact day-to-day operations, including shipping, on-demand, energy, and the supply chain (to name just a few).

Take utilities, for example. According to McKinsey, a typical utility company sees up to $1.4B in storm damage costs and lost revenue due to outages from storms over a 20-year period.

With actionable weather forecasts, businesses can better prepare for weather events, save money, and improve operations all in the same process.

With the shutdown of Dark Sky Weather API, many people have sought after a better weather API for their weather data needs. But how do you know what’s the right choice for you?

Whether you’re building an app, adding weather data to your software platform, or embedding data into a home assistant, you may be looking for very different capabilities from a free weather API.

That’s where we can help!

Depending on your priorities, some APIs will be a better fit than others.

We looked at all the top weather APIs on the market in 2024 to help you choose the right one and get started faster.

Scroll down to learn what to consider when choosing the best weather API for your project or business this year.

What is a Weather API?

A weather API is an application programming interface that allows software developers to access and integrate weather data from various providers into their own applications and websites.

Weather APIs are similar to map APIs in terms of integration and versatility of data sources. Each service provider collects, aggregates, and processes meteorological and other relevant weather data then offers access to it via API.

As a developer, you likely already use APIs to perform different tasks and functions in your apps or across your site.

This data includes information such as:

  • Temperature
  • Humidity
  • Wind Speed
  • Precipitation
  • Cloud cover
  • Visibility
  • …and more

For example, if you are building a web or mobile app that needs to pull weather forecast data, the right weather API makes this easy. With this data, you can generate updates and alerts in web and mobile apps, creating solutions uniquely suited to your needs.

From on-demand weather forecasting to planning business operations, the use cases for a weather API are immense.

How to Choose a Weather API

With the number of weather APIs out there, there are a few things to consider before making your selecting.

You should be aware that each has unique capabilities, varying costs, and different degrees of reliability. Some even target specific markets or communities with unique features for agricultural applications or air quality monitoring.

Here’s what we recommend you consider.

Functionality and Scope

While most major weather APIs provide similar core functionality, they can vary in aspects like:

  • Data resolution and accuracy
  • Length of historical records
  • Date/time formats

Selecting an API that provides the specific weather data your app needs (e.g., marine conditions, weather on Mars) without unnecessary features is essential.

Free APIs often have limitations like:

  • Number of API calls
  • Functionality depth

So if building a commercial app that needs advanced weather data for a business use case, additional costs for premium APIs with more robust capabilities may be warranted.

Compatibility and Ease of Implementation

Most weather APIs today are based on RESTful architecture, with a handful offering a SOAP alternative. Be sure to pay attention to those subtle differences in date and time formats and well-tested compatibility with the app framework and language you’re coding in.

Another thing to take note of is the quality of API documentation.

While some services have in-depth tutorials and guides, others expect you to figure it out yourself or come armed with previous experience implementing weather APIs.

Depending on your level of expertise, you may want more documentation to effectively set things up.

Responsiveness and Reliability

You need a weather API to not only do what you want and well, but you want it to be fast and available. There are several sources for information on uptime and response speed of available weather APIs, but the information there is inconsistent or inaccurate.

The best way to find out which APIs are reliable and fast enough to make it into the production version of your app is to try them. Fortunately, most offer a free trial option or a freemium subscription.

Cost

Once you’ve determined the needs and scope of your project and narrowed down your list of potential weather API providers, it’s time to consider the price tag.

The features, uptime, capacity, and responsiveness offered by the free API services are inferior to those of paid options. That said, even the highest-priced APIs will become a significant expense only if and when your app’s number of API requests is exceptionally high.
