The weather in the park has alternated between mostly sunny and variable cloudiness, with rain and snow. In Yosemite Valley, daytime highs have been in the 50s with overnight lows in the 30s. In Tuolumne Meadows, the daytime highs have been in the 40s, the overnight lows have been in the single-digit numbers to the low teens, and there are 78 inches of snow. Even at this time of year, bears may break into cars in parking lots and campgrounds in search of food. Do not leave food in your car.
Bears can smell food in vehicle trunks and can break in.
All food, ice chests, and aromatic items should be stored in metal food storage boxes or hard-sided cabins. Keep a clean car and campsite, and throw away all trash. Once bears become conditioned to human food, they may become unnaturally aggressive and must be killed. You may enter the park 24 hours a day. Reservations are not needed to enter the park.
