Is there a "best" time of year to visit Yosemite? It depends what you're
looking for. The descriptions below represent average conditions.
Weather varies year by year, sometimes dramatically, and that affects
the wateralls, wildflowers, and road openings. Summer (June
through September)
See lots of the park...and other visitors
Areas to visit: All areas of the park are usually accessible
by car by late May or early June, although services along the Tioga Road
often open a bit later in June.
Climate: Warm to hot, with occasional rain (usually as
afternoon thundershowers, especially at the higher elevations).
Yosemite Valley & Wawona (4,000 ft / 1,200 m): 87°F (31°C) / 51°F (10°C)
Tuolumne Meadows (8,600 ft / 2,600 m): n/a
Rivers & Waterfalls: Most of the water flowing in Yosemite
comes from snowmelt in the high country, so runoff decreases during the
dry summer. Peak runoff typically occurs in May or June, with some
waterfalls (including Yosemite Falls) often only a trickle or completely
dry by August. Other waterfalls, including Vernal, Nevada, and
Bridalveil, run all year, however their flow can be very low by late
summer.
Wildflowers:
Yosemite Valley & Wawona- Most blooming occurs in June, with redbud,
Sierra onion, lupine, Mariposa lily, pentstemon, and flowering dogwood
beginning in May.
Tuolumne Meadows- The season begins in late summer for subalpine
flowers. Beginning around July, look for little elephant's heads,
gentian, pentstemon, yarrow, and shooting stars.
Fall (October & November)
See lots of the park, but few people
Areas to visit: All areas of the park usually remain open
through October, and sometimes into November. However short-term
closures may occur due to snow. Along the Tioga Road, services often are
not available after September and overnight parking is not permitted
after October 14th. Yosemite Valley and Wawona remain accessible by car
all year, however tire chains may be required, depending on conditions.
Climate: Quite variable, with weather ranging from hot to
cold, dry to rainy or snowy.
Yosemite Valley & Wawona (4,000 ft / 1,200 m): 54°F (12°C) / 35°F (2°C)
Tuolumne Meadows (8,600 ft / 2,600 m): n/a
Rivers & Waterfalls: Water levels tend to be very low, with
waterfalls (including Yosemite Falls) containing little or no water.
Some waterfalls, including Vernal, Nevada, and Bridalveil, run all year,
however their flow slows to a trickle by fall.
Fall colors: Yosemite is not known for having spectacular fall
colors because most of the trees are evergreen. Still, big-leaf maples,
black oaks, and other deciduous trees tend to be showy around
mid-October.
Winter (December through March)
A season of snow & solitude
Areas to visit: While Yosemite Valley and Wawona remain
accessible by car all year, the Tioga Road is closed (usually sometime
in November). Once closed for the season, vehicles are not permitted
between Crane Flat and Tioga Pass, including in the Tuolumne Meadows
area. The road to Glacier Point is also closed (usually sometime in
November). However from mid-December though early April, the Glacier
Point/Badger Pass Road is plowed to the Badger Pass Ski Area where both
downhill and cross-country skiing is popular. Tire chains are often
required on park roads. When they are, you must carry and know how to
use them, regardless of the type of vehicle you are driving.
Climate: Winter in Yosemite is snowy and cold, though sunny
and chilly days are not uncommon.
Yosemite Valley & Wawona (4,000 ft / 1,200 m): 53°F (12°C) / 28°F (-2°C)
Tuolumne Meadows (8,600 ft / 2,600 m): n/a
Rivers & Waterfalls: Water levels tend to be low, but once
some snow and rain have fallen, Yosemite Falls begins flowing again
(though not at springtime levels).
Spring (April & May)
The perfect season for waterfalls!
Areas to visit: While Yosemite Valley and Wawona remain
accessible by car all year, the Tioga and Glacier Point Roads remain
closed due to snow, often until late May. Tire chains sometimes are
required even during spring. When they are, you should carry and know
how to use them, regardless of the type of vehicle you are driving.
Climate: Highly variable, with sunny and relatively warm days,
but still an occasional winter storm.
Yosemite Valley & Wawona (4,000 ft / 1,200 m): 69°F (21°C) / 39°F (4°C)
Tuolumne Meadows (8,600 ft / 2,600 m): n/a
Rivers & Waterfalls: As warmer weather begins to melt the
snow, even the smallest creeks are rushing with water. You may see many
small, unnamed waterfalls and cascades all along the Valley rim. Larger
creeks and rivers, along with the better known waterfalls, tend to reach
peak runoff in May or June.
Wildflowers: It's too early for wildflowers in the park,
though you might see California poppies and other species at lower
elevations on your way to Yosemite. Redbud and dogwood also tend to
bloom in May.
