Winter in Yellostone Basics
The basic rule of thumb is to keep warm (but don’t sweat) and keep hydrated. The best dressed Yellowstone visitor always layers! Several, easily adjustable layers of clothing allow you to adjust to rapid changes in weather and temperatures. Many people don’t realize that weather conditions can vary from one part of the park to another.
You clothing should handle cold down to -35 to -40 degrees F. Be sure your clothing includes a windproof, hooded outer layer with wool or other insulated garments underneath. Wool or synthetic trousers and long underwear will help to keep your legs warm and dry in deep snow. (Snowmobile suits made of high quality technology materials can be rented by at snowmobile rental companies.) If skiing or taking a snowcoach tour, pack a pair of lightweight wind or rain-pants for provide extra warmth on windy days. Avoid cotton jeans and sweatshirts that do not allow sweat to evaporate.
The majority of heat is lost through the extremities so go the extra length for your hands, feet, and head. Wear a face mask-style stocking cap or parka hood when you need maximum protection. When snowmobiling, make sure that you have a baklava or head sock on under your helmet. We have ones with extra thickness around the neck area or just make sure to wear a warm, turtleneck type long underwear and/or sweater.
Thick wool socks and gaiters over boots help to keep your feet warm and dry. Wear gloves or wool mittens with shells that breathe to allow moisture to escape from sweaty hands. Good boots, rated to -40°, are essential when snowmobiling.
Yellowstone’s high altitude and dry climate require a little extra packing. Always pack extra water and continue sipping it during the day. I know that sounds funny when surrounded by millions of gallons of frozen water, but the dry climate drains moisture quickly from people without realizing it and you get cold quicker. The added water helps.
Remember, high altitude sunlight reflected from snow is much more intense than at lower elevations; snow-blindness may occur if sunglasses are not worn. Wear dark glasses on sunny days. We even wear them on gray days. Apply sunscreen lotion to exposed skin to avoid sunburn.
