According to, Peoria, Arizona, is a vibrant city located in Maricopa County, in the central part of the state. Situated in the Sonoran Desert, Peoria is part of the greater Phoenix metropolitan area. The city’s geographical coordinates are approximately 33.5806° N latitude and 112.2374° W longitude. As with many locations in the Sonoran Desert, Peoria experiences a unique and characteristic desert climate, which influences its weather patterns throughout the year.

The climate in Peoria is classified as a hot desert climate, also known as a “BWh” climate according to the Köppen climate classification system. This designation is typical for regions in the Sonoran Desert and signifies extremely hot summers, mild winters, and low annual precipitation. Understanding the climate of Peoria involves exploring its temperature variations, precipitation patterns, and other meteorological factors.

One of the defining features of Peoria’s climate is its scorching summers. From late spring to early fall, residents and visitors can expect exceptionally high temperatures. Daytime highs often soar above 100°F (37.8°C), and it’s not uncommon for the mercury to reach well into the 110s°F (43.3°C). These extreme temperatures are a result of the city’s location in the arid desert environment, where intense sunlight and minimal cloud cover contribute to rapid heating.

Summer nights in Peoria are relatively warm, with overnight lows rarely dropping below the mid-70s°F (23.9°C). This characteristic of warm nighttime temperatures is common in desert climates, as the arid conditions allow for efficient radiational cooling during the evenings. The lack of moisture in the air prevents significant heat loss, maintaining relatively warm temperatures even after sunset.

To cope with the intense summer heat, residents and visitors in Peoria often rely on air conditioning systems and other cooling measures. The city’s infrastructure and buildings are designed to handle the extreme temperatures, and outdoor activities are generally planned for the cooler early mornings or evenings.

Contrasting the sweltering summers, Peoria experiences mild and pleasant winters. Daytime highs from late fall to early spring typically range from the mid-60s°F to low 70s°F (18-23°C). Winters in Peoria are characterized by clear skies, abundant sunshine, and lower humidity compared to the summer months. While daytime temperatures are relatively mild, nighttime lows can occasionally drop into the 30s°F (1-4°C). Although frost is infrequent, it’s not unheard of during the coldest winter nights.

The transition between summer and winter in Peoria is marked by a brief but noticeable fall season. During this time, temperatures gradually decrease, and residents can enjoy cooler evenings and mornings. Fall in the Sonoran Desert is often accompanied by clear skies, making it an ideal time for outdoor activities.

Rainfall in Peoria is scarce and irregular, typical of desert climates. The majority of precipitation occurs during the winter months, from November to March, with January being the wettest month on average. The city receives an annual average of around 9 inches (229 mm) of rainfall. Rain events are often short-lived but can be intense, leading to localized flooding due to the arid soil’s limited ability to absorb water quickly.

In addition to rainfall, Peoria experiences occasional dust storms, commonly known as haboobs. These intense dust storms are typically associated with thunderstorms and can result in reduced visibility and hazardous driving conditions. Haboobs are more prevalent during the summer monsoon season when moist air from the Gulf of California interacts with the hot desert air.

The climate of Peoria is greatly influenced by its proximity to the Sonoran Desert and the geography of the surrounding region. The city is part of the Valley of the Sun, a broad, flat basin surrounded by mountain ranges, including the White Tank Mountains to the west and the Hieroglyphic Mountains to the north. These geographical features contribute to Peoria’s climate by influencing temperature patterns and limiting the amount of moisture that reaches the area.

Peoria, Arizona, experiences a hot desert climate characterized by scorching summers, mild winters, and minimal rainfall. The city’s weather is shaped by its location in the Sonoran Desert, with high temperatures and low humidity dominating the summer months. Winters are marked by milder temperatures, clear skies, and occasional precipitation. Despite the challenging summer conditions, Peoria’s residents have adapted to the climate, making the most of the city’s sunny days and enjoying the unique aspects of life in the Arizona desert.
