Cloud Free Night displays ACCESS and GFS model forecast maps over specific Australian regions and New Zealand, and forecast meteograms for a variety of locations, summarising the weather forecast over the next five days. The official forecasts from the Australian Bureau of Meteorology and links to local (WeatherWatch, Skippy Sky, OzForecast) and overseas (Meteologix, Yr, Clear Outside, meteoblue, 7Timer!) weather forecasts, are available to enable further comparison of these weather predictions.

Cloud Free Night displays high-definition Himawari-8 satellite images and synoptic charts from the Australian Bureau of Meteorology, and cloud camera images over Australia and New Zealand. The satellite imagery are displayed at their original resolution and zoomed over specific areas of Australia and New Zealand. The cloud camera images include those from aviation weather cameras, all sky cameras and webcams around Australia.
