Mount Shasta is located at 41°18'52" North, 122°18'41" West (41.314542, -122.311510),<ref name="GR1">{{cite web|url=https://www.census.gov/geographies/reference-files/time-series/geo/gazetteer-files.html|publisher=[[United States Census Bureau]]|access-date=April 23, 2011|date=February 12, 2011|title=US Gazetteer files: 2010, 2000, and 1990}}</ref> along [[Interstate 5]] south of [[Weed, California|Weed]] and north of [[Dunsmuir, California]].

According to the [[United States Census Bureau]], the city has a total area of {{convert|3.8|sqmi|km2}}, of which {{convert|3.8|sqmi|km2}} is land and only 0.10% of it is covered by water.

The area hydrology consists of an unnamed stream in the south part of town which joins Big Springs Creek, which then flows south as Cold Creek to join the headwaters of the South Fork of the [[Sacramento River]].<ref>[[U.S. Geological Survey]], ''Weed 15 Minute Quadrangle'', U.S. Government Printing Office, Washington DC (1954)</ref> The typical depth to [[groundwater]] is quite shallow in the predominant alluvium.<ref>''Phase I Environmental Site Assessment,301 West Lake Street'', Mount Shasta, California, Earth Metrics Incorporated, San Mateo, California, Report Number 10363, December 18, 1989</ref>

The settlement is on the distal gently sloping southwest flanks of Mount Shasta, with the chief surficial soils being [[Quaternary]] [[alluvium]]. This alluvium is adjacent to and probably underlain by [[volcanic]] clastic rock deposited by Mount Shasta in the course of its development. Groundwater elevation is approximately at the elevation of the underlying native black [[peat]] soil. Where it occurs this peat, of approximately two feet thickness, is underlain by stream deposit sands and gravels.

=== Climate ===
Mount Shasta to the east forces moisture out of the air as it rises and cools, and the dip in the [[Klamath Mountains]] allows more moisture to reach inland, so the city receives more precipitation than the semiarid region to the north. This means that in the winter, the city gets nearly {{convert|103|in|m|2|disp=or}} of snowfall despite its low {{convert|3600|ft|m}} elevation.<ref>[http://www.skimountaineer.com/CascadeSki/CascadeSnowSitesInfo.html Information about Cascade Snowdepth Measurement Sites], Skiing the Cascade Volcanoes, April 2005, accessed April 23, 2013</ref> Other towns in the region get much less snow,<ref>[http://skimountaineer.com/CascadeSki/CascadeSnow/SnowdepthComparison.gif Cascade Snow Depth Comparison], Skiing the Cascade Volcanoes, April 2005, accessed April 23, 2013</ref> for example [[Yreka, California|Yreka]] averages only {{convert|11.8|in|m|2|disp=or}}, and much cooler [[Klamath Falls, Oregon|Klamath Falls]] only {{convert|35.9|in|m|2|disp=or}}. The [[Köppen climate classification]] is ''Csb'', or warm-summer Mediterranean climate. It can be very warm and cold according to the Californian summer anex. The USDA [[Hardiness zone#Selected U.S. cities|hardiness zone]] is 7b.

The record high temperature was {{convert|106|F|C}} on July 29, 2022, and the record low temperature was {{convert|-13|F|C}} on December 22, 1990.<ref name = "WB">[http://www.weatherbase.com/weather/weather.php3?s=389540&cityname=Mount-Shasta-California-United-States-of-America Mount Shasta, California Monthly - Weather Averages Summary], Weatherbase, accessed April 23, 2013</ref> The wettest “rain year” was from July 1997 to June 1998 with {{convert|76.24|in|mm|1}} and the driest from July 1976 to June 1977 with {{convert|13.06|in|mm|1}}. The most rainfall in one month was {{convert|27.48|in|mm|1}} in January 1995, including {{convert|5.97|in|mm|1}} on January 9.
