The climate of Nevada

Nevada climate is mainly of arid and semi-arid types (Köppen climate classification BWh/BWk, BSh/ BSk), with hot summers and cold winters. Nevada lies in the Western United States and is the driest state in the union. California in the west, Oregon in the northwest, Idaho in the northeast, Utah in the east, and Arizona in the southeast, share borders with the state. The Pacific Ocean and the desert regions in the south influence the dry climate of the state.

Nevada, the Silver State, is mostly arid, with an average elevation of 1608 meters and highest of 4401 meters at Boundary Peak. The geography consists of desert lands and semi-arid regions of the Great Basin. The Mojave Desert is in the south, while the Sierra Nevada and Lake Tahoe lie in on the western boundary. The southern portion has flat terrain and receives less rain. Mountain ranges above the desert plains consist of lush forests. The Snake River's tributaries drain the north, while the Colorado River drains the southern portion of the state. The Sierra Nevada is home to several rivers, including the Carson, Truckee, and Walker rivers. The vegetation is of alpine and sub-alpine types in the high mountains.

Summers are severely hot and dry in Nevada, with the difference between day and night temperatures, often exceeding 40°F (4.4°C). Day highs frequently stay above the 100°F (37.8°C) mark from June to September and even top 120°F (48.9°C). Winters are long and cold in the north but short and mild in the south. Daytime highs average a comfortable 57°F (13.9°C) in Las Vegas at the peak of winter, while the nights are above freezing at 38°F (3.3°C). Spring is warm, while the autumn has pleasant conditions. Winter minimum temperatures register in the 15°F (-9.4°C) to 20°F (-6.7°C) range in the plains, and temperatures below 0°F (-17.8°C) seldom last for more than a few days.

The annual rainfall is scarce and hardly averages 7" (178mm) in Nevada, with the majority of the precipitation on the leeward side of the Sierra Nevada. The average precipitation ranges from 5" (127mm) in the south to 12" (305mm) in the north. Western and south-central portions record maximum precipitation in the winter, central, and northeast in the spring and eastern during the summer. Snowfall is heavy between 20" (508mm) in the central and 30" (762mm) in the northern regions, while the south receives occasional light outbursts. Humidity rarely exceeds 60% throughout the year. The freeze-free season ranges from 70 days in the extreme north to 225 days in the south. Nevada receives ample sunshine of 3300 hours over the year.

Laughlin recorded the highest ever temperature of 125°F (51.7°C) on June 29, 1994, in Nevada, while San Jacinto recorded the coldest temperature of -52°F (-46.7°C) in the winter of 1972.

The best time to visit Nevada

The best time to visit Nevada is in the shoulder seasons from March to May and September to November. The spring is cooler than the summer, which tends to be severely hot and uncomfortable in much of the state. The fall season brings color to the landscape and is calmer than the spring and summer. Thunderstorms are frequent in late spring and summer, while mid-summer to early fall experiences tornadoes. The diurnal temperature range is the shortest during April and October, which makes the conditions comfortable.

The worst time to visit Nevada

The worst time to visit Nevada is during the winter as the state experiences cold weather with occasional extreme temperatures. Although extended periods of frigid weather are rare due to high mountain ranges in the north and east, arctic masses spill through them to produce cold waves. Low temperatures drop below freezing in many parts, and sometimes even below 0°F (-17.8°C). The scanty rainfall is responsible for creating cold deserts in much of Nevada. The north and central regions are susceptible to heavy snowfall, particularly in the high mountains. Snowfall over 45" (1143mm) is possible in twenty-four hours, and amounts over 330" (8382mm) in the winter are not rare. However, the cold season is to the liking of snow lovers who find joy in sports like skiing and hunting.

Weather hazards

Nevada is vulnerable to thunderstorms, droughts, floods, wildfires, earthquakes, and tornadoes in late spring and summer. The plains witness flooding in spring and summer due to the melting of snow and rain from thunderstorms, with the Nevada Floods of 2013 as a notable example. Cloudbursts may bring more rain in a few hours than the entire season. The dry conditions and scanty rainfall are responsible for severe wildfires at the peak of the summer in much of the state. Nevada also experiences frequent earthquakes of low intensity below 3.5 on the Richter scale. Wind speeds are high across the vast plains with the lack of high mountain ranges to provide natural barriers. Pacific storms occasionally bring heavy snow in the winter.

Weather in January
