Yosemite Park Weather in July

Averages By Month

July and August are the hottest months in Yosemite National Park with highs of 90°F. In July the sun is also shining for the longest amount of time - 12 hours on average each day. So the weather conditions are absolutely ideal for exploring the beautiful surroundings with a hike or bicycle ride. Even in July, temperatures can cool down to lows of 56°F - so it’s always a good idea to pack a light jacket. The rivers and lakes all around Yosemite National Park stay cool with average water temperatures of 57°F, even in summer. Fittingly for all the outdoor activities you may be planning is that it’s very dry in July with only 1 rainy day on average. Given the dryness, some of the typically stunning waterfalls might have less water flowing now.

July is a very busy time in Yosemite National Park so it’s advisable to book your trip well in advance. If you manage to secure a spot, you will be able to enjoy the whole of the park now as the winter road and trail closures have fully reopened. And you will also be able to see nature at its best with the wildflowers in full blossom too.

Best Time to Visit Yosemite Park

Yosemite National Park has something fantastic to offer throughout the year. A great time to visit might be between May and July when the rivers and lakes are filled to the top with meltwater and the waterfalls are most impressive. For walking and hiking the months between May and October are ideal as the vegetation will show its most stunning side.

In summer you might even want to go for a swim although the water in the rivers and lakes always stays relatively cold with highs hardly ever reaching 70°F. Spring and fall are particularly pleasant, never getting too hot or too busy. Winter in Yosemite National Park is great for anyone into winter sports - don’t forget the snow chains if driving!

Things to know about Yosemite Park

Yosemite National Park is one of the most popular national parks in the United States with around 4 million visitors each year. In July and August it can get very busy and weekends during that time especially get quite crowded with additional ‘local’ visitors from San Francisco and Los Angeles. But most of the visitors head to the area around Yosemite Valley as it’s easy to reach by car. You might find more peace during that time if you explore other areas of Yosemite.

A little bit about the park’s history: the US Senate protected the area of 1500 square miles back in 1890. In 1906 the National Park was extended to include Yosemite Valley and Mariposa Grove.

The Park has 4 entrances: 1 northwest, 1 west, 1 south and 1 from the east via the Tioga-Pass which is only open in summer. Whichever entrance you choose, you will have to pay different entrance fees depending on whether you are coming by car, motorcycle or by foot.

Besides some incredible nature, including North America’s tallest waterfalls, the park offers some remarkable flora and fauna. You will be able to see 37 different kinds of trees including mammut trees. Yosemite National Park is also the place to see never before seen herbs and wildflowers on the many beautiful fields. Some animals like grizzly bears and wolves have sadly been made extinct from the area but you can still see black bears, pumas, ground squirrels and many more…

Do stay alert given that there are some bears and pumas around! Bears aren’t actually that dangerous for humans. But when they are looking for food they can destroy whole tents and damage cars badly. That’s why in the national park you can only store food in special boxes. This is particularly important when camping! Encounters with pumas, aka mountain lions, on the other hand will be rare but you must follow certain rules to be safe. You should stop and slowly retreat or, in case of necessity, scream and shout but never run!
