Introducing the OpenWeather History API Full Archive

Posted on 25 Oct 2021

There is barely an industry that is not affected by our climate. From agriculture to construction, logistics to retail. Having direct API access to finely-detailed, long-term archival weather information for a specific location has never been so important.

The OpenWeather History API Full Archive gives up to 40 years of detailed weather data for any specified global location.

The World Bank has recently announced their support for “Climate-Smart Agriculture”, whose aim is to increase productivity and resilience, while reducing emissions on a global scale. Direct API access to the OpenWeather long-term climate data would enable organisations that supply agricultural data and applications to target any global location, without the need to know the location in advance.

Understanding long-term weather and climate data also benefits all stages of the building construction lifecycle, from site selection and initial design to the final build. Dublin’s latest construction project, the €750m LinkedIn campus, has achieved a staggering 70% reduction in energy consumption for the final building, while also contending with demanding weather conditions for the building works. Access to the detailed, site-specific, historic weather data through the OpenWeather API interface can be incorporated to the latest Building Information Modelling software solutions.

The OpenWeather API can be used within internal applications to give consistently accurate and detailed weather data for analytics and Machine Learning. The long-term nature of the data (40 years), coupled with geographical accuracy can give the retail industry valuable insights into the effects of weather and climate on consumer behaviour for specific locations.

The OpenWeather 40 years full archive consists of three distinct stages:

  • The first API is called, specifying the required geographic coordinates. Our system will return the location ID, and start the calculations (learn more here).

  • The second API is called to check the status of the calculations… and see a full list of registered locations (learn more here).

  • When the calculations are complete (due to the volume of data, this will normally take about 30-40 mins per location), the third API is called with the location ID, and the required time period (up to 40 years) to retrieve the historical weather data. You can export the whole 40-year archive as well, if you like (learn more here).

The data returned by the API includes precipitation (rain/snow volume), air temperature, feels like, wind speed and direction, pressure, humidity, cloudiness, and many others. An example of the API response can be seen here:
