Cloud Free Night is a non-profit online weather forecast information service, for the benefit of the Australian and New Zealand astronomy community. 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. The Cloud Free Night website has also been optimised for mobile devices.

Testimonial"I use your service very frequently for my photography... and recommend your service as the best tool to understand if there will be good cloud for sunrise/sunset and of course astrophotography... Thanks for creating a wonderful platform for us to get a greater insight into what the clouds are doing. Your service has helped me create some of my best images, and I am very grateful..."

This is the best way to appreciate the value of all the features in Cloud Free Night.
Cloud Free Night provides forecast maps over specific Australian regions and New Zealand, and meteograms summarising the forecast over the next ten days for particular locations. The maps allow you to toggle between the GFS and ACCESS models at any point while the meteograms (time-series graphs) present detailed cloud information or a summary comparison of the two models.
Cloud Free Night displays the latest radar images and high-resolution Japanese Himawari-8 satellite images via the Australian Bureau of Meteorology, including animation of the most recent images. The radar images are presented without location names using a modified colour palette for greater clarity. The high-definition satellite images are conveniently matched to the forecast map regions.
Cloud Free Night is a personal project of Robert Dahni (retired Meteorologist) with the advice and support from Phil Hart and the Australian and New Zealand astronomy community. Please contact us if you would like a meteogram for your home town location or your club's observing site. We would also like to hear your suggestions to enhance the Cloud Free Night service or the website experience.
