The climate is a hot issue and weather forecasting technology is suddenly cool. The urgent need for innovative weather and environmental conditions forecasting solutions is obvious whether you believe in climate change or not. In fact, climate is not only the topic of discussion around the water cooler. There are businesses, entire industries in fact, where weather conditions have a direct impact on day-to-day business operations. Industries like logistics, aviation, competitive outdoor sports, public safety, mining and agriculture (to name just a few), are directly impacted by the weather. . For these industries weather forecasting accuracy can mean the difference between ending a fiscal year in profit or loss For example, according to the National Air Transportation Association, in the last week of January 2014 alone, were cancelled in the United States. . 7,000 flights Every flight delay costs $78 per minute ! In the UK, experts estimate the cost of bad weather to to the economy as a whole at 1 billion GBP / day However, at least . Inaccurate weather forecasts can cost millions of dollars and even human lives. So it’s no wonder so many developers are choosing to include weather forecast updates and alerts in web and mobile apps, and create solutions that are uniquely suited to the needs of enterprises. some of the costs can be prevented with accurate weather forecasts Even the fitness band on my wrist is alerting me of potential weather hazards as I type this post. But that’s just the tip of the proverbial iceberg. For enterprises, the features of existing weather forecasting apps are far from enough. Many of these organizations turn to in-house development of custom apps to collect, process and display weather and environmental data relevant to enterprise operations, optimally also drawing weather data from multiple reliable sources. How to Choose a Weather API for Your App If you are building a web or mobile app that needs to pull weather forecast data and historical information from large databases, you will need to use an API (Application Programming Interface). It’s simply more affordable and efficient than developing and maintaining your own. As a developer you should be accustomed to employing APIs to perform different tasks and functions in your apps. . Each service provider collects, aggregates and processes meteorological and other relevant data, then offers access to it via API (among others) for free or for a cost. There are quite a few such service providers, each with a unique set of capabilities, a varying cost and different degree of reliability. Some even target specific markets or communities with unique features for agricultural applications and air quality monitoring. Weather APIs are similar to map APIs in terms of integration and versatility of data sources With the broad selection available, choosing one (or more) weather API for your app can be challenging. So what should you consider before you scroll down to our list of recommended weather data API providers? Functionality & Scope Like any API you integrate with your mobile or web app, the weather API you choose needs to do what you want and it needs to do it well. . However, before you request an API key for each available service offering the functionality you need, be sure to define your scope as well. Overall, the majority of APIs will give you similar data, but will vary in resolution, the length of time back in historic weather records, as well as day and time formats For example, your app users are only interested in marine weather conditions or (yes, that’s a thing), there are specific APIs that will give you the data you need without any unnecessary features or capabilities packaged in. the weather on Mars That said, it’s worth noting that free APIs can only give you so much and are limited not only in the number of API calls but also the functionality provided. The bottom line is that additional functionality comes with additional costs, which becomes especially relevant if your commercial app targets a vertical or business with specific needs that go beyond your general weekly forecast and current weather data. Compatibility & 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, as well as well-tested compatibility with the app framework and language you’re coding in. Another thing to take note of is documentation. . While some services have in-depth tutorials and guides, others expect you to figure it out yourself or come armed with previous experience in implementing weather APIs Responsiveness & Reliability You need it to not only do what you want and well, but you want your weather API of choice to be fast and available. There are a number of sources for information on uptime and response speed of available weather APIs, but the information there is not very consistent or accurate. . Fortunately, the majority of them offer a free trial option or freemium subscription. Which leads us to another important criteria: the price. 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 Cost Once you’ve figured out your needs and scope, and narrowed down your list of potential weather API providers, it’s time to consider the price-tag. As one can expect, . That said, even the highest priced APIs will become a significant expense only if and when the number of API requests made by your app is extremely high. the features, uptime, capacity and responsiveness offered by the free API services is inferior to those of paid options Top 8 Weather APIs for 2020 1.
