If you want to know what the weather was in a certain location at a certain date in the past, the Weather History API gives you the answer. Make queries based on coordinates, and the feed will provide you the observational data of the day. The standard response includes both daily summary values and hourly values. The Weather History API provides observational weather information from the past by showing measured weather parameters in a certain location at a specific date.
The API delivers all the measured weather parameters as both daily summary values and hourly values. The queries can be made based on a given day and coordinate point. The API will respond with observational data from the nearest relevant weather station or from weather forecast model data (augmented observation) in JSON format. Augmented observations are provided when the closest weather station with sufficient observations is too far away to give representative information.
The weather history service includes measurements from the following official weather stations.
The following parameters are available in one-hour time steps.
The daily summary parameters, the average, minimum and maximum values are based on the hourly observations of the day.
