Announcing Updates to the OpenWeather One Call API 3.0

"Nothing is more simple than greatness; indeed, to be simple is to be great." - Ralph Waldo Emerson

The OpenWeather One Call API 3.0 is a complete, sophisticated yet simple, weather API that can be used within a range of applications to give accurate, useful and wide ranging weather data. 

The functionality of this already feature-rich product has been significantly broadened by OpenWeather to also provide an incredible 1.5 year ahead daily aggregation forecast. For the first time, users can gain an insight into daily aggregated weather data, including six types of temperature, cloud cover, precipitation, pressure, wind speed etc. for up to 1.5 years ahead. This ground-breaking new feature can open new horizons for users involved in a wide variety of industries and scenarios.

In addition to the 1.5 year ahead daily aggregation forecast, OpenWeather has added the ability for users to retrieve timestamped weather data up to a 4 days ahead. With this feature, nuanced forecast data can be discovered for any global location, for any single timestamp for the next 4 days (as well as over 40 years in the past). This means that 4-day timestamped forecast weather data such as UVI, clouds, pressure, visibility, wind, humidity, sunrise etc. can now be at the fingertips of users.

Importantly, these two innovative new features come at no additional cost to the user, and are included in the existing pricing plan of the One Call API 3.0, which even included 1,000 free API calls per day.    

These changes have been seamlessly blended by OpenWeather into the existing One Call API 3.0 endpoints, meaning that developers can instantly leverage this dramatically expanded functionality with little development time. 

Although the applications for these improvements are limited only by our imagination, possible scenarios might be:    

Insurance Industry:

The versatility of this single product can be used by insurers in differing areas of their business. The time machine aspect can provide weather data for any particular timestamp, meaning that claims can be easily verified using weather information such as sunrise and sunset, visibility, temperature, wind etc. The same OpenWeather product can be used to provide historical data to help insurers build their own internal data models, along with the far-reaching 1.5-year forecast data that the models can then be applied to. This would enable insurers to limit their weather exposure, as well as giving them a competitive advantage within the industry.

Retail Industry:

The well known uncertainties that surround the fickle buying patterns of the world’s population can be greatly reduced by having clear, succinct and far-reaching weather forecast data. Now, with the new developments around the OpenWeather One Call API 3.0, retailers, manufacturers, and logistics organizations can coordinate their efforts by having easy access to the new 1.5 year daily aggregated weather forecast data. The time that seasonal products will gain in demand can now be forecast in advance, allowing for greater understanding about the timing of changes between the seasons, and the relative demand for products. 

This not only helps retailers and manufacturers maximize their revenues and reduce their risk, effectively manage inventory and warehouses, but also ensures that the consumer has access to the products they need, when they need them.

With over 100 billion garments being produced by the fashion industry every year, these changes could be used to reduce the 92 million tons of clothing that is disposed of in landfills. Helping reduce waste, carbon emissions, and the environmental impact on local communities and wildlife has never been so important. 

One Call API 3.0 contains 3 endpoints to provide access to the data: 

1. Current Weather and Forecasts:

This Current and forecasts weather data endpoint provides:

• Minute step forecast for one hour

• Hourly step forecast for 48 hours

• Daily step forecast for 8 days

• Government weather alerts

2. Timestamp Weather Data:

This weather data for any timestamp allows users to receive weather data for a specific timestamp in the past or future. The timestamp can be chosen from the 1st of January 1979 to get historical data till 4 days from now for getting weather forecasts.

3. Daily Aggregation

This daily aggregation endpoint provides access to aggregated weather data for a particular day from 2nd January 1979 up until 1.5 years forecast ahead.
