Frost is common in the winter months.  Snow is rare in the CBD (central business district) due to being on the leeward (eastern) side of the range, but the surrounding areas get annual snowfall through winter and often the snow-capped Brindabella Range can be seen from the CBD. The last significant snowfall in the city centre was in 1968. Canberra is often affected by foehn winds, especially in winter, evident by its anomalously warm maxima relative to altitude.
