Wedding Weather for Las Vegas Weddings this Weekend
Las Vegas' climate is typical of the Mojave Desert, in which it is located, marked with hot summers, mild winters, abundant sunshine year-round, and very little rainfall.
High temperatures in the 90s °F are common in the months of May, June, and September and temperatures normally exceed 100 °F (38 °C) most days in the months of July and August, with very low humidity, frequently under 10%.
The hottest temperature ever recorded is 117 °F (47 °C) set twice, on July 19, 2005, at McCarran International Airport and July 24, 1942, at present-day Nellis Air Force Base.
Winters are cool and windy, with the majority of Las Vegas' annual 4.49 in (114 mm) of rainfall coming from January to March.
Winter daytime highs are normally around 60 °F (16 °C) and winter nighttime lows are usually around 40 °F (4 °C).
The coldest temperature ever recorded is 8 °F (-13 °C) set on January 25, 1937, at present-day Nellis Air Force Base. Showers occur less frequently in the Spring or Autumn.
July through September, the Mexican Monsoon often brings enough moisture from the Gulf of California across Mexico and into the southwest to cause afternoon and evening thunderstorms. Although winter snow is usually visible from December to May on the mountains surrounding Las Vegas, it rarely snows in the city itself.
Las Vegas is situated on the arid floor within Clark County.
Correspondingly the environment is dominated by desert vegetation and wildlife; however, the setting is also subject to torrential flash floods which the infrastructure of storm sewers has not been able to contain.
The rapid pace of urban development beginning in the 1980s has produced more impervious surface and exacerbated the inherent flooding issue.
Enabling the rapid population expansion was a major addition to the city's sewage treatment capacity, an event removing a major constraint to population growth in the 1970s.
The sewage treatment expansion resulted from a U.S. Environmental Protection Agency grant funded 208 program to analyse and forecast growth and environmental impacts through the year 2010.
