Best time to observe in Melbourne?!

Summer. We actually see sunshine and clear skies, and better seeing than in winter. April thru to Sept is essentially permanently overcast and ice cold wintry hell with an endless precession of cold fronts. You may get the odd clear night here and there, usually seperated by weeks and often falling on a full moon plagued by crap seeing. Transparency however tends to be best during the cold half of the year. Those occasional cold clear nights in winter without the moon are tops for galaxy and nebula observation.

Skippy sky is good with cloud forecasts, but do yourself a favour and ignore their seeing predictions. Skippy sky's seeing predictions is based on the presence of the jetstream, and doesn't take into account any lower level atmospheric activity.
