Hi
The first half of this year was disastrous for cloud cover down this way. The same pattern is evident in the RDO Moorook data (which is a wonderful resource). The plot below of Moorook Jan-Jun monthly average clear nights is self explanatory - over about a decade, we have gone from about 2 nights in 3 being clear to about 1 in 3. Included a linear regression - if it keeps up this trend, we will not have any clear nights at all within another decade
. Hopefully, if the clouds are all here, they are not somewhere else.
