Comparing the Temperature Data
Average Highs – Phoenix Hotter
When it comes to average high temperatures, Phoenix takes the crown as the hotter city compared to Las Vegas. With scorching summers and mild winters, Phoenix boasts an average high of around 100 degrees Fahrenheit (38 degrees Celsius) during the summer months.
This is slightly higher than Las Vegas, which sees average highs in the mid-90s (around 35 degrees Celsius). The intense heat in Phoenix can be attributed to its location in the Sonoran Desert, where the lack of vegetation and the abundance of concrete contribute to the urban heat island effect.
Average Lows – Phoenix Milder
While Phoenix may be hotter in terms of average highs, it also enjoys milder average low temperatures compared to Las Vegas. During winter nights, Phoenix experiences lows in the mid-40s to mid-50s (around 7 to 12 degrees Celsius).
In contrast, Las Vegas can dip down to the mid-30s (around 1 to 3 degrees Celsius). This difference can be attributed to the higher elevation and cooler desert nights in Phoenix.
Record Temps – Las Vegas Hotter
When it comes to record-breaking temperatures, Las Vegas takes the lead in being the hotter city. While both cities experience extreme heat, Las Vegas has seen higher temperatures historically. In 1937, Las Vegas recorded its highest temperature of 117 degrees Fahrenheit (47 degrees Celsius), while Phoenix reached a maximum of 122 degrees Fahrenheit (50 degrees Celsius) in 1990.
These scorching temperatures remind us of the blistering heat that these desert cities can experience.
Precipitation – Las Vegas Drier
When it comes to rainfall, Las Vegas is known for its arid climate. The city receives an average of just 4.2 inches (10.7 cm) of rainfall annually, making it one of the driest cities in the United States.
Phoenix, on the other hand, receives slightly more precipitation with an average of 8.3 inches (21.1 cm) per year. However, both cities experience very little rainfall and rely heavily on irrigation and water management systems to support their populations.
Elevation & Topography – Impacts on Heat
The difference in elevation and topography between Phoenix and Las Vegas also plays a role in their respective temperatures. Phoenix sits at an elevation of around 1,100 feet (335 meters) above sea level, while Las Vegas is situated at approximately 2,000 feet (610 meters) above sea level.
The higher elevation in Las Vegas contributes to slightly cooler temperatures compared to Phoenix. Additionally, the surrounding mountain ranges in both cities can affect temperature patterns, with the Spring Mountains providing some relief to Las Vegas from the intense desert heat.
Heat Waves, Monsoons and Dry Heat
Phoenix Heat Waves
Phoenix, Arizona is known for its scorching heat, with summer temperatures often exceeding 100 degrees Fahrenheit. The city experiences frequent heat waves, which are prolonged periods of excessively hot weather.
These heat waves can last for several days or even weeks, pushing the temperature well beyond the normal range. In fact, Phoenix holds the record for the highest number of days with temperatures above 100 degrees Fahrenheit in a year.
During a heat wave, Phoenix residents and visitors are advised to take precautions to stay safe and cool. This includes staying hydrated, seeking shade, and limiting outdoor activities during the hottest parts of the day.
Air conditioning is a necessity in this desert city, and many local businesses and public spaces offer refuge from the sweltering temperatures.
Las Vegas Heat Waves
Las Vegas, Nevada is another city notorious for its extreme heat. Like Phoenix, it experiences frequent heat waves during the summer months. However, while the average temperatures in Las Vegas are slightly lower than those in Phoenix, the city still sees its fair share of scorching hot days.
During a heat wave in Las Vegas, it is important for residents and visitors to take similar precautions as those in Phoenix. Staying hydrated and seeking air-conditioned spaces are essential. Many hotels and casinos in Las Vegas have extensive air conditioning systems, providing relief from the intense heat for both locals and tourists.
Monsoon Season Cooling
Both Phoenix and Las Vegas experience a monsoon season, which brings relief from the intense heat. The monsoon season typically occurs in the summer months and is characterized by heavy rainfall, thunderstorms, and high humidity.
During this time, the temperatures in both cities can drop significantly as the rain cools the air. The monsoon season also brings much-needed moisture to the desert landscapes, rejuvenating the flora and fauna.
However, it is important to note that monsoon storms can also bring flash floods and strong winds, so it is crucial to stay informed and take necessary precautions.
The ‘Dry Heat’ Debate
When discussing the heat in Phoenix and Las Vegas, the term “dry heat” often comes up. Both cities are known for their low humidity levels, which can make the high temperatures feel more bearable. However, the notion of “dry heat” being more comfortable is subjective and varies from person to person.
Some people find the dry heat of the desert more tolerable, as the lack of humidity allows sweat to evaporate quickly, providing a natural cooling effect. Others may find the dryness uncomfortable, as it can lead to dry skin, dehydration, and respiratory issues.
Ultimately, whether one prefers dry heat or not is a matter of personal preference.
