Cloud Free Night is an online weather forecast information service for the benefit of the Australia & New Zealand astronomy and photography communities. It is unique in offering a comparison of the widely available forecasts from the United States GFS global model with higher resolution forecasts from the Australian Bureau of Meteorology ACCESS model.

*** LATEST NEWS *** ACCESS-C, ACCESS-R and GFS model forecasts are only available for the next three days. Currently unable to download ACCESS-G global model data from the Bureau of Meteorology. Forecast maps and meteograms for Days 4-10 are not available. All other products are being generated as expected"

Cloud Free Night displays forecast maps over specific Australian regions and New Zealand, and meteograms summarising the forecast over the next three days for particular locations. The maps allow you to toggle between the GFS and ACCESS models at any point while the meteograms present detailed cloud information or a summary comparison of the two models.

Cloud Free Night displays the latest Himawari-8 satellite images and synoptic charts from the Australian Bureau of Meteorology, and the most comprehensive set of links to cloud camera images around Australia. The high-definition satellite images are available over many areas covering the Australia and New Zealand regions. The synoptic charts include the satellite image as background. The cloud camera images include those from aviation weather cameras, webcams and all sky cameras.

Cloud Free Night is operated by a small team from the Australia astronomy community.

We would like to hear of your experience in using, or suggestions to improve, the Cloud Free Night service.
