As the previous poster stated "...summer is over..."! Snow can come at any time.
During our time in Zermatt this year from 5 September to 15 September snow was a fairly common occurrence depending on the altitude. Regarding Gornergrat specifically, during the previous mentioned time frame there were three days when snow was present in quantities to allow the making of snowballs and snowmen!
