Summer Overnight Gear List

Printable Version

An average mid-summer day on Mount Washington has a high temperature of about 53°F and an overnight low of about 42°F. Freezing temperatures can occur during any month of the year. Average winds in summer are about 25 mph, with hurricane-force gusts possible. Thick, wet fog occurs on about 90% of the days in summer, and precipitation is measured on more than 50% of the days in summer.

Cotton clothing of any sort is unsuitable because of its tendency to absorb and hold moisture. Suggested materials are listed for each item:

  1. Wicking base layer: wool or synthetic long underwear tops and bottoms to pull moisture away from the skin
  2. Insulating mid-layer: midweight wool or synthetic tops and bottoms to wear over your base layer to provide insulation
  3. Insulating top layer: midweight wool, synthetic, or down jacket to layer over your base layer and mid-layer
  4. Wicking hiking pants: synthetic pants that can be worn over your base layer and insulating layer
  5. Rain jacket and rain pants: durable, rugged, waterproof top and bottom to protect from rain and wind (no lightweight plastic rain gear or ponchos)
  6. Sturdy hiking boots: rugged boots that fit well and are broken in
  7. Socks (2 pair): wool or synthetic socks (not cotton) that fit comfortably in your boots
  8. Hat: Wool or synthetic cap that covers your ears
  9. Mittens or gloves: insulated, windproof, and water resistant
  10. Glove liners: thin wool or synthetic gloves to use in lieu of insulated gloves when the weather is warmer
  11. Sunglasses: sturdy sunglasses with UVA and UVB protection
  12. Daypack: durable, water-resistant, or waterproof backpack that's large enough to hold your layers, water bottle, and camera. Approximately 20-30 liters (1220-1830 cubic inches) recommended size
  13. Water bottle or hydration pack: minimum 18 oz capacity
  14. Hiking poles, trekking poles, ski poles, or walking stick (optional)
  15. Loungewear and/or pajamas: a comfortable top and bottom to wear when you are indoors and sleeping. Since you will be going indoors and outdoors several times throughout the day, you will remain in your outerwear and do not need more than one change of clothes
  16. Slippers: something to wear indoors instead of your boots (optional)
  17. Camera and extra batteries (optional)
  18. Sunblock (optional)

Toiletries

Bring all necessary toiletries and medications, including an extra couple of days worth of medications in case adverse weather delays departure. There is nowhere to purchase toiletries or medications on the summit.

Bedding

A pillow and fitted sheet will be provided. You will need to bring your own blanket or sleeping bag. We suggest also bringing earplugs, as you will be sharing a bunkroom with fellow trip participants.

Special Equipment

If you are bringing a camera or other special equipment, remember to bring your charger and extra batteries. There is nowhere to purchase electronic equipment on the summit, and batteries die very quickly in the cold.

Other Gear

Personal gear not listed above should be kept to a minimum, as space in the vehicle and bunkrooms is very limited. Please pack just what you need on the mountain, and leave the rest in your car or hotel.
