Cool New Research Addition – Predict Cloud Cover

22 08 2010

Hey Folks

Somebody showed me a very cool site for predicting cloud cover.   It’s a tool for astronomers, but obviously it has great uses to Landscape photographers.   You can zoom in on specific parts of Australia (and other parts of the world too) and it gives you cloud cover predictions for several days in the future.  now I don’t know about you, but I reckon that is very cool.

To check it out just go to

Thanks to Bill Owens for this great research site.  I’ll be including this as part of my standard research now.

Very handy.

This could certainly avoid the immense frustration of turning up somewhere to be assaulted with a plain sky which is utterly boring and extremely difficult to photograph when facing the east in the morning.

That is a very great tool indeed, Brent. Super handy for us lazy seascapers who don’t want to get up at 4am to look out of the window in search of clouds.
No more wasted early rises, yes! :))

What a fantastic idea!

Glad you found the site useful Brent, it’s certainly a handy tool and worth checking before committing to a shoot.

I’ve found it to be mostly accurate, but on the very odd occasion, totally wrong 🙂

Great post! You have my undying gratitude.

Hi, As the author of SkippySky, I can tell you that the underlying weather model produces averages over a 3 hour period. The input data has a resolution of 0.25 degrees square, or about 15km by 15 km per single data point. You cannot expect pinpoint precision from broadbrush inputs…

I urge you to think in terms of trends in the data, and overlay that with your own local knowledge.

Having said that, many astronomers find the cloud forecasts to be quite accurate.

And yes, sometimes the damned computer model gets it all wrong in spectacular fashion!

Note especially that the contour colours represent 10% bands. e.g.
the dark blue represents 0..10% coverage – and 10% can look like a lot of cloud. Dark blue does NOT mean absolutely no clouds.
