It’s warming up in Yosemite National Park this weekend. Make sure you are prepared. 🌡️
Yosemite is experiencing a heat wave, with temperatures reaching over 100°F (37.8°C) in Yosemite Valley this weekend. Stay cool and safe by checking off our summer safety list:
🛟 If you plan to swim, choose popular beaches along the shores of the Merced River in Yosemite Valley, or Tenaya Lake in Tuolumne Meadows. Always use caution when walking near rivers, waterfalls, and other water sources—rocks are extremely slippery, and currents can remain dangerous even when water levels are low.
💧 If you feel thirsty, you’re already dehydrated. Drink water before, during, and after your activities. Free water stations are available throughout the park for refilling bottles. Take advantage of them whenever possible. Don’t forget to eat salty snacks, too!
🐾 Protect your pets by checking pavement temperatures. If the sidewalk is too hot to touch with your hand, it’s too hot for their paws. Don’t leave your dog in the car.
🌅 Hike early in the morning or later in the evening when it’s coolest. Take frequent breaks in the shade, and wear sun-protective clothing along with a wide-brimmed hat.
👵 Check on family members who may be more vulnerable to heat-related illnesses, especially the elderly, young children, and those with medical conditions.
💫 Recognize the signs of heat exhaustion and heat stroke: fatigue, dizziness, nausea, and confusion. If someone shows confusion, loses consciousness, or has a body temperature above 103°F (39.4°C), call or text 911 immediately.
