Why is it so cold at night in the desert?
Because deserts have such little water vapor in the air, it makes it harder to trap heat or cold in a desert. At night, the sun no longer heats the desert and the heat from the day doesn't stay trapped. Because of this, some deserts can get cold at night, dropping to below 40F, which is definitely coat weather.
The Sonoran is a hot desert. Summer air temperatures routinely exceed 40°C (104°F), and often reach 48°C (118°F). These high near-surface temperatures interact with cool, moist air in the atmosphere to produce the violent thunderstorms of the summer monsoons.
- The Sonoran Desert is a North American desert which covers large parts of the Southwestern United States in Arizona and California and of Northwestern Mexico in Sonora, Baja California, and Baja California Sur. It is the hottest desert in Mexico. It has an area of 260,000 square kilometers (100,000 sq mi).
- The Mojave is a desert of temperature extremes and two distinct seasons. Winter months bring comfortable daytime temperatures, which occasionally drop to around 25 °F (−4 °C) on valley floors, and below 0 °F (−18 °C) at the highest elevations.
- Yakutsk is the largest city built on continuous permafrost, and many houses there are built on concrete piles. The lowest temperatures ever recorded on the planet outside Antarctica occurred in the basin of the Yana River to the northeast of Yakutsk, making it the coldest major city in the world.
Deserts have extreme temperatures. During the day the temperature may reach 50°C, when at night it may fall to below 0°C. Deserts have less than 250 mm of rainfall per year. The rain can be unreliable. Most deserts are found between 20° and 35° north and south of the equator.

- The Sahara covers large parts of Algeria, Chad, Egypt, Libya, Mali, Mauritania, Morocco, Niger, Western Sahara, Sudan and Tunisia, extends over 9 million square kilometres (3,500,000 sq miles), and it covers about 1⁄4 of the African continent.
- In addition to being extremely dry, the Sahara is also one of the hottest regions in the world. The average annual temperature for the desert is 86°F (30°C) but during the hottest months temperatures can exceed 122°F (50°C), with the highest temperature ever recorded at 136°F (58°C) in Aziziyah, Libya.
Average Temperatures for Phoenix. Phoenix's coldest month is January when the average temperature overnight is 43.4°F. In July, the warmest month, the average day time temperature rises to 104.2°F.
- In comparison, Phoenix is truly a safe safe big city. Sure there are some questionable areas, but tourists rarely wander into these places, especially if you are in Scottsdale. But, that is several hours away from Phoenix.
- According to the National Weather Service, Phoenix hasn't experienced "official measurable" rain in 85 days (and still counting). The last time there was rain in the Valley was Aug. 23. And that's not even the longest dry streak Phoenix has had.
