March can be a magical month at Jackson Hole if it's snowing—and it often is. In addition, the resort has long gone out of its way to attract more people to its slopes in March, when its skier days typically dip compared with previous months.
Jackson Hole has not traditionally been a ski area that people seek out for spring break, which can make a great bet for those looking for uncrowded ski runs. The ski area puts on a big concert at the end of the season, called the Rendezvous Spring Festival, usually luring a major act to play on the last weekend in March or the first weekend in April. The concert is free and it's usually mild at night compared with the lower temperatures of January and February.
Jackson receives copious amounts of snow throughout the winter, it's one of the best places to go seeking powder. March is no exception—skiers can find themselves amidst epic snow cycles all the way through April. When it's not snowing, however, skiers are usually rooting for corn skiing and sunshine at Jackson Hole.
Without good amounts of north-facing terrain, the resort can't keep snow chalky and cold during the warmer months of March. So if it's not warming up during the day, loosening up the snow, the skiing substrate can be very hard and downright icy if it clouds up. There are rare days in the spring when patrol won't open skiing from the top of the Tram when cloudy snowless days follow a string of warmth and sun.
What matters when it comes to snow for March skiing:
Ski areas with higher elevations and more northerly latitudes can keep snow colder when thawing temperatures in March or during warming events degrade other resorts' snowpacks. Aspects have the same affect, so the snow at a ski resort with more east or south-facing slopes will suffer more quickly as the sun grows stronger into March and the later spring.
For that reason, ski resorts with more north-facing terrain will be able to shelter snow more thoroughly into and through March. The most important factors for good snow preservation in spring tend to be elevation and north aspects, so the ski resorts with the highest elevations and the highest percentage of north-facing slopes tend to be those that preserve their snow best. More explanation on this topic can be found on our snow rankings page.
Lots of east and south exposures coupled with cold temperatures at night can put ski slopes into a nasty freeze-thaw process, wherein the ski resort becomes an ice rink overnight and doesn't revert to being skiable until the sun thaws things out. If the sun doesn't come out, however, skiers can be stuck with terrible conditions for days on end.
So, quite simply, in March, look for resorts with high elevations and high percentages of north-facing terrain (~50%+).
