Introduction
I thought these statistics could be interesting for climbers. Here are some climate statistics for several mountains in the United States (arranged from coldest to warmest for lack of any better way to do it).
There are only a few mountain tops with weather statistics and most of them are located in the Eastern USA. There have been at one time several peaks in the Western US with weather data, but few of the weather stations below are currently operating, though the data is still available if you dig hard enough for it.
Temperatures
Denali is not surprisingly by far the coldest of all the mountain tops in the United States. In fact, during summer Denali is still colder than any location in the lower 48 is during winter. It is also the coldest place in the world outside Antarctica.
Obviously Mount Rainier is by far the coldest of all these mountain tops in the lower 48. Interestingly though, Mount Rainier is about the same temperature in winter as Pikes Peak or Mount Washington. It is however, much colder in summer.
Mount Evans and Pikes Peak are much farther south than Mount Rainier, but I assume that the Pacific air on Mount Rainier keeps the mountain “milder”, temperature wise in winter than it would otherwise be. Mount Rainier is by far a much wetter and stormier mountain (precipitation wise) than Pikes Peak. Average annual precipitation at the summit is around 85 inches, which is significantly lower than the average of 117 inches of precipitation at Paradise Ranger Station at 5500 feet. Mount Washington averages near 99 inches, but the summers are too “warm” for glaciers to form. Locations such as White Mountain Peak (California), White Mountain 2 (California), Pikes Peak (Colorado), and Climax/Fremont Pass (Colorado) sit in rain shadows, and are thus very dry considering the altitude. The mountains around Alta and Snowbird (such as Mount Baldy with an estimated average annual snowfall of 732 inches) Utah are probably the snowiest locations in the Rocky Mountains and snowfall compares well to the snowiest locations in the Cascades, though water content is much lower, and permanent snow and glaciers are almost non-existent, with only a few small remnants remaining.
White Mountain Peak in California is colder than Mt Washington on average, but is a little warmer than Mount Washington in winter. It is still warmer than one might expect, but part of that may be attributed to the fact that temperatures in the area have been on the hot side since data has been available. On average, White Mountain 2 at a lower elevation is as cold as Mount Washington. However, it is also “warmer” in winter and cooler in the summer than Mount Washington.
Mount Mitchell is much warmer than these other peaks, but interestingly the all time record low (-34) is almost as cold as the other locations (except Denali). Mount Washington has recorded temperatures down to -47, Mount Blue Sky (Mount Evans) down to -40, Pikes Peak down to -39, Mount Mansfield down to -39, Mount Rainier down to -36, and White Mountain 2 down to -35. All these mountains only have a span of 13 degrees between their all time record lows.
As far as extremes on Denali go, an old minimum gauge thermometer left on the summit of plunged to -95. Since the thermometer sat on the ground, it isn't official, but temperatures have been thought to drop at least to -77. Another thermometer was placed at 15,000 feet by the U.S. Army Natick Laboratory, and was there from 1950 to 1969. The coldest temperature recorded during that period was −100. In the summer, it is likely that the summit never reaches freezing.
Records for Mount Mitchell, Mount Washington, and Mount Mansfield span many decades, while the other mountains have record for much less time.
The longest period for a high elevation Western US mountain top belongs to White Mountain 2 where data was collected for 25 years. Some of the mountain passes in Colorado have records for longer than this. If you count Western Texas as part of the Western US, Mount Locke has a very long period of record, but it isn't as high as many other mountains in the Western US. It is about as high as the highest mountains in the Eastern US though and makes an interesting comparison.

Wind Speed
Unfortunately, wind speed data is hard to obtain for most of these mountains. Of all these mountains, Mount Washington is the only one with long term wind data. Other than wind data for Mount Washington, I could also find it for Pikes Peak, Mount Evans, and Longs Peak in Colorado; White Mountain Peak in California; and Camp Muir in Washington. Longs Peak and Mount Washington are about the same in wind speed and both are significantly windier than Pikes Peak. Mount Evans compares fairly well with Longs Peak and Mount Washington, but the extreme wind speeds are much lower.
Denali might be the windiest place in all of North America. The Denali Pass weather station averaged 18 m/s or 40.3 mph 1994-1996 and 2003-2004. This is windier than any place known in the Lower 48. Computer models have predicted that maximum wind gust on Denali have exceeded 300 mph (such as during the
storm that wiped out the Wilcox Expedition), but of course such a figure is a calculated estimate rather than an actual measurement. On day in February 1995 had sustained (not just gusts) of 154 mph. The summit of Denali is probably windier than Denali Pass.
Mount Rainier might be the windiest place in the lower 48, but average wind speeds come from an interpolation, rather than measured data. Mount Washington had a record wind gust of 231 mph on April 12 1934. Longs Peak had a record wind gust of 201 mph in 1981, but the station only lasted a short time and has a lot of missing data. 2000 feet lower than Longs Peak, Trail Ridge, north of Longs Peak has recorded gusts of 157 mph, also in 1981. Unfortunately, Long Peak doesn’t have any actual temperature measurements compiled (at least that I know of); only wind, so wind chills are hard to compare. More than likely, Long Peak is similar in temperatures to Pikes Peak and Mount Evans, but a little colder.
Temperatures below are only estimates based on readings from the other 14er weather stations and comparing it to Longs Peak's location. During the period of record, Pikes Peak had an estimated maximum wind gust of 150 mph, but the anemometer blew away 112 mph. Mount Evans has recorded wind speeds of 123 mph (some sources report a gust of 150+ mph, but I can't find when this was recorded), which is significantly less than that of Mount Washington or Longs Peak, but the period of record for the maximum wind gust was only 1994-1996. Had the period of record been longer, the maximum wind gust would likely be higher.
Hidden Peak (Utah) next to Mount Baldy has recorded wind speeds of 124 mph on November 8 1986, but wind readings are only taken sporadically. White Mountain Peak is about in the average range between all these mountain tops, but has recorded winds over 150 mph on several days. The highest wind speed recorded was 162 mph on December 19 2008.
Supposedly Grandfather Mountain recorded a 200 mph wind gust in January 2006, but this is not an official figure since the roof of the building on which the gauge was placed was suspected to have an amplifying effect. The highest official wind speed on Grandfather Mountain was 121 mph in December 2012. Grandfather Mountain must have data for average wind speed somewhere, but I have been unable to find it.
The Camp Muir wind data comes from actual data from the weather station at Camp Muir, but no period of record is given. The Mount Rainier wind data is an interpolation of the Camp Muir data. It seems no wind data is available for the other summits listed below. It would be interesting to see how windy the other high peaks in the Cascades or California are compared with the Rockies or Appalachians.

Sources: Statistics are from the book Skywatch West by Richard A Keen, page 247 and are based on weather balloon data. Unfortunately only January and July info is available. The -23F figure for July comes from the Weather Station located at 19,000 feet.
The below are interpolated from the Denali Pass Weather Station which operated 1990-2007. Temperatures were interpolated with the average temperature drop expected between Denali Pass and the summit. A 10 degree (F) average diurinal was assumed. This data shows "warmer" temperatures than the Skywatch West source/weather balloon data summarized above, though record highs (even at 18,200 feet) never approached the 30F estimate above during the period of record, so the 30F estimate in Skywatch West is likely too high. For some reason, the record lows at Denali Pass are quite a bit "warmer" than the ones at the weather station at 19,000 feet as well (which recorded temperatures in the -70s on multiple occasions). Stay tuned for average monthly wind speed calculations.

Source: Remote sensor 1998-2014(?). May not be operating currently-I can't find it online anymore? The nearby weather station at the top of the Collins Lift at 10,443 (625 lower than Mount Baldy) is still operating and has wind speed data too. Next to Mount Baldy and only 75 feet lower, Hidden Peak also has a weather station that records current temperatures, at least during ski season. Snowfall statistics are estimates for Hidden Peak at Snowbird Ski Resort. See also pg. 19 of Utah's Weather and Climate (1996). Pg 19 November through April snowfall for Snowbird Summit (Hidden Peak, ~11,000 feet) = 634 inches.

Source: Both the Western Regional Climate Center and the Hawaii Atlas have weather data for Mauna Kea. Unfortunately, the data averages from either source does not match well. The data from the atlas was here used because it is the most complete. Average precipitation values are higher and low temperatures lower than the WRCC averages, which only includes data from a short time span. The all time records were taken from the WRCC, but several values in the database have been deemed inaccurate (such as the oft report record low of 12F in May 17 1979) and were thus purged from the above report. Period of Record: 1972-1982; sporadic
