The two primary weather streams that affect skiing in Kashmir originate in the northwest and the southwest. During the early months of the ski season, the snow is coming from the Arabian Sea and carries a relatively high moisture content. As the season progresses, the northern weather stream begins to dominate. As the two streams begin to mix, the drier air from the northwest of Kashmir combines with the southern stream and it begins to snow, A LOT. Gulmarg receives more snow than anywhere else in India and is known for the champaign (extra dry) powder that it receives as the season progresses. A single storm can easily deposit more than a few meters of snow. Its high elevation in Kashmir keeps the snow around for many later months of the year, making late season ski days possible!
The ski season in Kashmir typically starts in early December and goes until sometime in April. 2011 experienced an unusually dry early season but has since adjusted to more normal levels. Much snow can easily be found on the summit above Gulmarg in late March and in April, though the base area has very little to show. This part of the season offers a nearly empty mountain with great upper conditions for those who are aware of this secret.
