Each cell is one month: the share of days with 30 cm or more of modelled natural snow at mid-mountain over the last 11 winters, from brown (often thin) to deep blue (snow-sure). Blank means almost none.

None of the 5 resorts Cirque models in Australia has had a month that was snow-sure in 9 of the last 11 winters. The best single month was August at Perisher (6 of 11 winters). Treat natural snow here as a bonus and check snowmaking.
