Mt Whitney

Whitney Portal Sign
Weather on Mt Whitney varies greatly during the year and can certainly be unpredictable at times. Temperatures at the lower elevations are generally warm. At higher elevations in the night, even in the summer months temperatures can fall below freezing. Typical winter temperatures above 9,500 feet range from -14 degrees F to 12 degrees at night and from 15 - 50 degrees F during the day.

Ninety five percent of total precipitation (which includes both rain and snow) falls between the months of October and May, with more than half falling in January, February, and March. The frequency of summer showers increase at higher elevations and correspondingly there are more cloudy days. But even though these thundershowers are of short duration they are still a danger to the hiker/climber on the summit or high ridges on Mt Whitney and other Sierra Peaks. That being said, if you detect a thunderstorm developing, vacate the summit and high ridges at once. The first recorded fatality on Mt Whitney was due to lightning.

Snow is one of the most spectacular features in the Sierra Nevada (the second snowiest mountain range on the continent) but due to the fact that Mt Whitney resides in the southern portion of the Sierra Nevada, it does not get nearly the amount of snow pack that the Palisade or Mammoth Lakes region do.

Quick summary of Mt Whitney weather and road access for the next 7 days:
Sunny and mostly clear for the next seven days on Mt Whitney.

The Whitney Portal access Road is open. The quota system for hiking/climbing Mt Whitney is in force until the 1st of November, so you will need a permit for hiking or climbing Mt Whitney.

"Therefore everyone who hears these words of mine and puts
them into practice is like a wise man who built his house on
the rock. The rain came down, the streams rose, and the winds
blew and beat against that house; yet it did not fall, because
it had its foundation on the rock. But everyone who hears these
words of mine and does not put them into practice is like a
foolish man who built his house on sand. The rain came down,
the streams rose, and the winds blew and beat against that
house, and it fell with a great crash."
