There is consistently high air pressure over Arizona because it's also very hot. Because of the high pressure, the air sinks, which means that clouds cannot form. The state of Arizona experiences arid and high temperatures due to its topographical and geographical importance. Other reasons include its proximity to the equator and the lower elevations of most of Arizona.
Typically, during the summer months, high pressure sets in eastern Arizona and is in a good position to bring rain to southeastern Arizona. Summer temperatures in Arizona are usually in the range of 90 degrees Fahrenheit to 120 degrees Fahrenheit. “If I have to work outside, I wear shorts so I can get in and out of the pool and stay cool,” said Arnold, a native of Arizona who owns a marble and granite business. The temperature surpassed 110° F on four consecutive days and did not fall below 80° F at night last week in the city of Arizona, breaking several records.
Both of these reasons contribute to the increase in temperatures in Arizona and the fact that clouds cannot form in this region. Summer temperatures in Arizona range from 90 degrees Fahrenheit (32.2 degrees Celsius) to 120 degrees Fahrenheit (48.9 degrees Celsius). Phoenix, the capital of Arizona and the fifth largest city in the United States with 1.6 million inhabitants, is used to a warm desert climate, but temperatures are rising due to global warming and urban development, which has created an extensive heat island of asphalt and concrete that traps heat, especially at night. Arizona is an urban heat island (UHI) where surrounding areas that absorb more heat experience higher temperatures.
People who check weather maps regularly will notice that there is often a big H nearby or directly above Arizona. The Laguna Mountains in California act as a barrier between the state of Arizona and the cold air of the Pacific Ocean. Arizona's temperatures are expected to rise even more in the coming years, leading to drought-like conditions in the state. It turns out that Arizona is close to one of the places in the Northern Hemisphere where all that sinking air ends up.
If you live in Arizona, you may already be used to the heat, but for tourists and visitors, Arizona can be unbearably hot, especially during the summer months. One of the barriers between the state of Arizona and the fresh air that flows from the Pacific Ocean is the Laguna Mountains in California.
