What to Pack By Season

Here is a handy general guide for what to pack in each season in Yosemite. It is meant to provide a quick overview but suggestions vary by your planned activity type and the current weather conditions expected during your visit.

Spring/Summer (April-September)

Spring/Summer is a beautiful time to explore. Early spring can be wet with cool evening temps and the occasional spring storm. Summer is very warm in the valley but can still be cool in the higher elevation parts of the park.  Summer time is consistently sunny with temperatures as high as low-nineties  (32°C) with a low of mid-fifties (13°C). Early spring can be high forties  (9°C) to low sixties  (18°C).

Spring/Summer Packing List

  • T-shirts and tanks
  • Shorts/Skorts
  • Well-worn hiking shoes or boots (waterproof boots maybe needed for early spring hiking as some trails may still have standing water or patches of snow)
  • Hiking socks
  • Hiking trousers or sport leggings (not denim or jeans)
  • Waterproof lightweight jacket or windbreaker (for cool evenings)
  • Sunhat with wide brim
  • Warm hat (for cool evenings)
  • Daypack, sunscreen, mosquito repellent, sunglasses and refillable waterbottle. Also a headlamp is a good idea in case you stay to watch the sunset on the trail and need to hike back in the dark.

Autumn (October/November)

Autumn is one of the best seasons for hiking Yosemite. The days are still generally warm and sunny but the nights are cool. Colors start to change around the valley floor but the first snows have not yet arrived meaning many areas of the park that are congested during the summer time or snowed in during the winter are accessible and relatively quiet. The seasons are transitioning so you may need to pack a little more to make sure you are ready for sunny warm days or rainy, cool ones. See spring/summer packing list above for ideas on what to pack, but consider bring a heavier waterproof jacket in addition to several layers.

Winter (December-March)

Winter in Yosemite is one of the most beautiful times to explore the Valley Floor. The high granite walls are dusted with snow and the meadows glisten with icy frost in the morning. You may encounter snow on the trails in the valley or you may not, it can vary greatly by year. However, it is almost certain some roads such as Tioga Pass and Glacier Point will be closed as will some hiking trails. Mirror Lake Trail, Upper Yosemite Falls Trail and the trail to Vernal Falls footbridge are generally good winter trails for those who still want to hike. Snowshoeing, downhill and cross country skiing, and ice skating are also popular winter activities. Temperatures range from mid-twenties (-2°C) at the lowest, to high fifties (13°C) on sunny days.

Winter Packing List

  • Warm hat that covers your ears
  • Fleece or other warm scarf
  • Gloves (waterproof, if planning to ski or snowboard)
  • Warm leggings or thermal underwear to wear under trousers
  • Light trousers (denim and jeans are not recommended)
  • Waterproof shoes or boots
  • Light layers, including short-sleeved shirts and sweaters/jumpers.
  • Heavy winter coat
  • Daypack, sunscreen, sunglasses and refillable waterbottle
