The weather in the park has been sunny to partly cloudy. In Yosemite Valley, daytime highs have been in the 50s with overnight lows in the 30s.

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. Firearms are prohibited in Yosemite National Park. You may enter the park 24 hours a day.
