Las Vegas Weather

Nevada is in the Southwestern desert

Las Vegas and the state of Nevada are located in Southwestern United States east of the Sierra Nevada Mountains in California. The entire state lies in the rain-shadow desert formed by the mountain range and receives very little rainfall.

The climate is extremely hot and dry. Most of the state only receives an average of four inches (10 cm) of rainfall per year, with more than 250 days of sunshine. Summers are quite hot with temperatures frequently exceeding 100 degrees F (40 C). In the winter months, daytime temperatures are usually a quite comfortable 60 - 70 deg. (15 - 20 C) with chilly nights. Early spring and late autumn are the best times to visit as the days are quite warm and the nights very pleasant.

Las Vegas is a great oasis

Las Vegas is located at the southern tip of Nevada in a broad flat basin surrounded by barren mountains. The city itself forms a huge oasis in this desert valley. Palm trees line the streets, green grass and flowering shrubs surround the homes. This illusion is maintained by the millions of gallons of water imported from nearby Lake Mead and the massive amounts of electricity provided by Boulder Dam.

The land in Nevada is rugged, forbidding and sparsely populated yet strangely beautiful. Most of it looks like the "Old West" as seen in many cowboy movies. The entire state lies in a unique geological formation called the "Basin and Range" area. It it is characterized by hundreds of small parallel mountain ranges interspersed with countless desert valleys. The infrequent rainstorms in the mountains cause violent erosion that carves deep canyons and disgorges sediment into the dry valleys. At times, the mineral-laden water forms broad shallow lakes that dry up in the intense heat leaving gleaming white salt flats.
