Guessing the 2007 Peak Snow Depth

Fun with numbers

Guessing the 2007 Snow Depth

Perisher Valley historical averages
MonthRain/Snow fall
Mar 125mm
Apr 120mm
May 155mm
Jun 200mm
Jul 200mm
Aug 250mm
Sep 245mm


All rain/snow for 06 was well below average.

March was 46% below average in 06, and snow depth was 81cm, also about 50% of the long-term average.

I'd say the March rainfall indicates the season peak depth.

*Very low rainfall, and quite warm.


From the March rainfall, I'd say the snow depth in 2007 will be (145/125 * 120) = 139.2cm.
