Carson Pass Weather Resources


This weather page is concerned with providing weather information to hikers and backpackers on or near the Pacific Crest and Tahoe to Yosemite Trail routes through Carson Pass and The Carson Pass Management Area South of the Lake Tahoe Basin.

These Weather Resources cover the Highway 88 Corridor across Cason Pass. Carson Pass lays just South of the Lake Tahoe Basin and on the North end of the Mokelumne Wilderness

Besides the weather information we will find links to the maps, miles, resupply, permit, and elevations information for the PCT and TYT here, and to our North and South.

It's time to hit the trail.

Real Time Ground Reporting Stations

Planning our gear selection for our hike South from Lake Tahoe we have referred to a reasonable selection of real-time ground reporting stations that inform about temp, wind, rain, snow, and humidity.

This real-time data gives us both current and historical knowledge of the range of temperatures we can expect to experience at various points down the trail.

This information establishes our gear selection range.

Trail Guide Information


This Weather Page, like the trail guide it is a part of, covers the High Sierra Trails from Meeks Bay along the Western Shore of Lake Tahoe down to the Mount Whitney Portal.

Therefore the trail guide splits into two branches departing the South Lake Tahoe Basin near Carson Pass. The Tahoe to Yosemite Trail route tracks Southwest around Carson Pass on its way over Round Top onto the low Western Flank of the Sierra Nevada along the rough passage through Summit City Creek.

The Pacific Crest Trail hikes through Carson Pass passing along the Eastern fringe of the whole Round Top Massif following the high Eastern flank of the Sierra Nevada Crestline South to Ebbetts Pass.

Be Ready for the Range: Basic Facts Basic High Sierra Weather Resources for the Backpacker

The Sierra Crest is noted for having the capacity to produce four seasons of weather during a single Summer Day.

Rain, snow, hail, fog, lightening, and a bit of sunshine can all happen in quick sequence.

The High Sierras are noted for rapid changes in weather and temperature, and the sudden appearance of harsh weather trends. You may experience anything from intense heat to bitterly cold Summer snow storms. Or you may not.

In any case, weather must be considered and proper gear preparations made to deal with the range of weather BEFORE entering the High Sierras.

Long Distance Backpackers who were on the High Sierra Crest in early August of 2009 experienced just such a series of Summer Snow Storms.

Temperatures dropped to the high teens and low twenties, snow and hail fell which partially obscured the trails, and all of those who entertained the misconception that the Sierras only have fine weather during the Summertime were bitterly disappointed. Luckily for the many backcountry travelers who were not properly prepared, those storms blew apart, rather than consolidated and deepened.

Weather considerations should guide your gear selection.

Weather Preparations for Backcountry Travel

All Seasons

Always check the National Weather Service Satellites, Maps, and Forecasts

The NWS Satellites will give you an orbital view of potiential storm activity far off the coast of California. Combined with the NWS Maps and Forecasts, you can anticipate weather. Note: especially check the 28km infrared and water vapor animations.

Check the National Weather Service Maps

NWS Maps Note: Especially Check the 24 to 48 Hour fronts and Precipitation Maps.

Consult the National Weather Service Home Page

The National Weather Service Home Page displays large and small scale weather warnings which may pertain to your High Sierra backpacking plans.
