From the impact of the jet stream to the city’s weather-related tourism and events, we’ll delve into the intricacies of Las Vegas’s weather in May.
The typical high and low-pressure systems that affect the region in May are a crucial factor in understanding the city’s weather. The article will discuss the average temperature range and how it changes throughout the day, as well as the relative humidity and dew point levels during this month.
Weather Patterns in Las Vegas during May
Las Vegas, known for its hot desert climate, experiences a significant change in weather patterns during May. The month marks the beginning of the wet season in the region, with a gradual increase in temperatures and precipitation.
Typical High- and Low-Pressure Systems
The weather in Las Vegas during May is influenced by two dominant high-pressure systems: the subtropical high-pressure belt and the polar front jet stream. The subtropical high-pressure belt, located over the region’s southwest, brings hot, dry air from the desert southwest, resulting in scorching temperatures. On the other hand, the polar front jet stream, located over the Pacific Ocean, introduces cooler, more moist air into the region, causing an increase in precipitation.
Atmospheric Conditions
During May, Las Vegas typically experiences an average high temperature of 84°F (29°C) and an average low temperature of 62°F (17°C). The atmosphere is characterized by high atmospheric pressure, low humidity, and an increasing amount of sunshine throughout the month. The dry desert air makes it challenging for the region to retain moisture, resulting in a moderate 6.9 inches (17.5 cm) of rainfall on average during May.
Impact of Jet Stream
The polar front jet stream plays a significant role in shaping Las Vegas’ weather during May. The jet stream brings a trough of low pressure, which, when combined with the subtropical high-pressure belt, creates a region of low pressure that moves from west to east. This process contributes to the occurrence of thunderstorms and showers in the region.
- Temperature extremes: Las Vegas typically experiences an average of one heatwave and two cold fronts during May.
- Precipitation patterns: The region receives most of its rainfall during thunderstorms and showers, which usually last for short periods.
- Atmospheric circulation: A complex interplay between the subtropical high-pressure belt, the polar front jet stream, and the low-pressure trough contributes to the varied weather patterns in Las Vegas.
The jet stream’s influence on Las Vegas’ weather makes it challenging to predict short-term weather conditions. However, understanding its impact on the region’s atmospheric circulation helps meteorologists make more accurate long-term forecasts.
Temperature and Humidity in Las Vegas in May
May in Las Vegas brings warm temperatures, but the highs don’t usually reach extreme levels. The desert landscape and dry air contribute to this relatively stable climate. The overall temperature during the month averages in the mid-60s to low 80s Fahrenheit (18-29°C), but daily fluctuations can be significant.
Average Temperature Range
The average high temperature in Las Vegas during May is around 84°F (29°C), while the average low is around 61°F (16°C). This variation in temperature is typical for the region, with temperatures often rising to the mid-80s (29-30°C) by the middle of the month. However, even though the average temperature fluctuates, the temperature can sometimes reach extreme highs during a heat wave.
Relative Humidity and Dew Point Levels
Las Vegas in May experiences a relatively low relative humidity, ranging from 10% to 30% during the day. This low humidity is due to the dry desert air. However, the dew point temperature, which is the temperature at which the air becomes saturated with moisture, can reach as high as 50°F (10°C). This difference between the relative humidity and dew point levels contributes to the dry atmosphere.
Extreme Heat Waves in May
Las Vegas has experienced several heat waves in May, with the hottest temperatures occurring in the first two weeks of the month. A notable heat wave in May 2016 brought temperatures over 100°F (38°C) for several days, with the highest temperature reaching 109°F (43°C) on May 18th. This heat wave was one of the deadliest in Las Vegas history, with several fatalities reported due to heat-related illnesses.
Precipitation and Storms in Las Vegas in May
Las Vegas, known for its arid desert climate, experiences a relatively dry May, with precipitation being a rare occurrence. However, when it does rain, it can come in the form of sudden and intense thunderstorms. These storms can bring flash flooding, hail, and even tornadoes, making them a significant concern for residents and visitors alike.
Average Rainfall and Snowfall in Las Vegas during May
Las Vegas typically receives very little rainfall in May, with an average of less than 0.5 inches (13 mm) throughout the month. Snowfall is extremely rare, with the city’s average elevation of 2,000 feet (610 meters) being too low to support significant snow accumulation. The few instances of snow in Las Vegas occur when a strong cold front moves through the area, bringing temperatures down and causing snow to fall at higher elevations.
Historical Accounts of Severe Thunderstorms in Las Vegas, Weather in las vegas on may
Las Vegas has experienced its fair share of severe thunderstorms in May. One notable example is the “Las Vegas Flood of 2004,” where a severe thunderstorm brought heavy rainfall, causing the Virgin River to overflow and flood parts of the city. The flash flooding resulted in significant damage to property and infrastructure, prompting authorities to issue evacuation orders.
Formation of Dry Lines and Haboob Storms in Las Vegas
The dry line is a region where a dry air mass meets a moist air mass, creating a boundary that can lead to the formation of thunderstorms. In Las Vegas, the dry line often forms when a dry air mass from the east meets a moist air mass from the Gulf of California. This interaction can lead to the development of haboob storms, characterized by strong winds, blowing dust, and reduced visibility.
Severe Thunderstorm Examples in Las Vegas
Severe thunderstorms in Las Vegas can range from small cells to large complexes, bringing heavy rainfall, hail, lightning, and strong winds. Some notable examples include:
- The 2018 severe thunderstorm outbreak, which produced several tornadoes and caused significant damage in the Las Vegas Valley.

Atmospheric Conditions and Health Risks in May
During the month of May, Las Vegas experiences a mix of sunny and dry conditions, which can have a significant impact on the atmospheric conditions and health risks in the region. On one hand, the high temperatures and intense sun exposure can lead to heat-related illnesses and skin damage, while on the other hand, the pollutants and particulate matter in the air can exacerbate respiratory problems and other health issues. It is essential to understand the atmospheric conditions and health risks associated with this time of year in order to take necessary precautions and protect one’s health.
Particulate Matter (PM) and Ozone (O3) Levels
The particulate matter (PM) and ozone (O3) levels in Las Vegas during May are a cause for concern. PM refers to tiny particles in the air that can come from natural and human-made sources, such as dust, pollen, and vehicle emissions. Prolonged exposure to high PM levels can lead to respiratory problems, cardiovascular disease, and even cancer. The O3 levels, on the other hand, are formed when nitrogen oxides and volatile organic compounds react with sunlight, resulting in ground-level ozone formation. The high O3 levels can exacerbate respiratory problems, such as asthma, and reduce lung function.
- According to the US EPA, the PM2.5 levels in Las Vegas during May can range from 10 to 30 micrograms per cubic meter.
- The O3 levels in Las Vegas during May can exceed the National Ambient Air Quality Standard (NAAQS) of 65 parts per billion (ppb) by up to 20%.
UV Radiation and Skin Cancer
The high UV radiation levels during May in Las Vegas increase the risk of skin damage, premature aging, and skin cancer. UV radiation is composed of two types: UVA and UVB rays. UVA rays can cause wrinkles and skin aging, while UVB rays are responsible for causing sunburns and increasing the risk of skin cancer. The high altitude and clear skies in Las Vegas make it an ideal location for UV radiation to penetrate the atmosphere, increasing the risk of skin damage.
