Bureau of Meteorology Grid Forecasts API

The Real-time Forecast Data API is a prototype API to our real-time forecast data, which will provide access to forecasts anywhere in the Australian region.

A detailed getting-started guide is available at https://developer.bom.gov.au/how-to-get-started which will walk you through the steps of obtaining an API key, registering your first application, and demonstrating a practical use of the API. The concepts you will need to be familiar with are REST APIs, using a "GeoHash" to provide location information as a part of the query, and using client-side code to work with the API. The type of data which is provided is forecast values in the JSON format.

The specific types of forecast information provided includes the temperature, and the amount of expected rainfall, on a per-three-hour basis. The daily maximum and minimum temperature are also available.
