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.
Latest Trail Conditions as of October 10th
The trail is in good condition (with only a slight snow dusting here and there) and still lots of people are going to the Summit without any problems. Permits are in force, so make sure you have one so you don't get turned around.

Matt 7:24-27 "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."
