According to the [[United States Census Bureau]], the city has a total area of {{convert|77.151|sqmi|km2}}, of which {{convert|0.003|sqmi|km2}} (0.72%) is covered by water.<ref name="CenPopGazetteer2023"/> St. George lies in a desert valley, with most of the city lying below 3,000 feet (900 m) in elevation. It is situated near a geological transition zone where the Colorado Plateau and Great Basin converge. The [[Beaver Dam Mountains]]/Utah Hill lie to the west, the [[Red Cliffs National Conservation Area]] and [[Pine Valley Mountains]] to the north, the western edge of the Colorado Plateau and Zion National Park to the east, and the [[Arizona Strip]] to the south. The [[Virgin River]], the Santa Clara River and the seasonal [[Fort Pearce Wash]] flow through the St. George valley and converge near the western base of [[Webb Hill]] near the city center.

The city uses street numbers rather than names, such as "East 100 South". Exceptions have been made for streets with curves or those not fitting into the traditional grid system. Some roads have names along with numerals, such as "400 East" which is also known as "Flood Street".<ref>{{cite web

===Climate===
St. George's arid climate is significantly warmer on average than the rest of the state, and more closely resembles nearby Las Vegas. The climate is cold [[desert climate|arid]] (''BWk''), though the average yearly temperature falls around 1°F below the hot arid classification. St. George has long, hot summers and relatively mild winters. The monthly average temperature ranges from {{convert|42.1|°F|C}} in December to {{convert|87.8|°F|C}} in July. On average, 60 afternoons have high temperatures over {{convert|100|°F|C}}, with an average window of June 29 through August 13, and 122 days with high temperatures over {{convert|90|°F|C}} with the average window fluctuating between late April and early October. About 60 mornings have low temperature drops to the freezing mark, with the historical average window between November 12 and March 14.

The highest temperature statewide was {{convert|118|°F|C}}, which was recorded in south St. George, near the Arizona border on July 4, 2007, breaking the previous record holder, at {{convert|117|°F|C}}, also set in St. George on July 5, 1985.<ref name = NOAA/> The record high minimum temperature is {{convert|89|F|C}} set on July 15, 1970, and July 3, 2013. Nighttime freezes are common during the winter due to radiational cooling. Both the record low temperature of {{convert|&minus;11|°F|C}} and record low maximum temperature of {{convert|17|°F|C}} were set on January 22, 1937; the record low temperature occurred again on January 26, 1937, both during the record cold month of January 1937 across the Western United States.<ref name = NOAA/>

The city has abundant sunshine year-round and averages about 300 sunny days per year, with an average {{convert|8.80|in|mm}} of precipitation annually.<ref name = NOAA/> The wettest "rain year" has been from July 2004 to June 2005 with at least {{convert|15.66|in|mm}} (some days were missing) and the driest from July 1973 to June 1974 with {{convert|3.89|in|mm|1}}. Record-breaking widespread flooding occurred during January 2005 when area creeks and rivers far exceeded their banks and washed out homes and some neighborhoods. The wettest month has been January 1993, when {{convert|4.74|in|mm}} fell. Precipitation is fairly evenly distributed throughout the year, except for a markedly drier period from April through June, which occurs after the Pacific storm season ends, but before the southwest monsoon begins, usually in mid-July. Precipitation mostly comes from the Pacific Ocean from late fall through early spring. The storm track usually lifts north of the city by mid-April. The monsoon brings localized and often intense thunderstorms from early July through mid-September. The greatest rainfall in 24 hours was {{convert|2.40|in|mm}} on August 31, 1909.<ref name = NOAA/>

The St. George valley occasionally receives wet or slushy snowfall in the winter, but what accumulates usually melts off by the mid- to late morning; the normal seasonal snowfall is {{convert|1.4|in|cm}}.<ref name = NOAA/> The earliest snowfall was measured on October 29, 1971, and the latest on April 11, 1927.<ref name = NOAA/> The record single-day snowfall is {{convert|10.0|in|cm}}, which was set on January 5, 1974. With the city having elevations ranging from {{convert|2500|to about|3500|ft|m}}, some areas such as Diamond Valley and Winchester Hills typically receive more snowfall and colder temperatures than the rest of the lower valley.
The most recent major snow event was on December 8, 2013, when between {{convert|6.0|and|8.0|in|cm}} virtually shut down the city, making it the third-heaviest snowfall in the city's history. Also significant about the storm was how low temperatures dropped and remained so for several days with daytime highs failing to reach the freezing mark, and one nighttime low temperature of {{convert|1|°F|C}}, recorded at the airport, was the coldest in the city in over 100 years. The cold spell killed or severely damaged much of the area's non-native vegetation, such as the [[Washingtonia robusta|Mexican fan]] palm trees.
