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:
A chance of rain/snow showers today then mostly sunny and clear for the rest of the week and into next on Mt Whitney.

Latest Trail Conditions as of September 8th
Pretty clear with a few water crossings up to Trail Camp at12,000 feet. Next, the 99 switchbacks going up to Trail Crest, mostly melted out, except for a bit of an icy patch in the cables section, any other snow patches up the switchbacks have a well worn boot path through them. On the backside of Whitney, things will go fine until near the end, where a bit of scrambling up the rock will enable you to avoid a lingering snow and ice field just before the Summit.
