Yuma, Arizona In 1995, Yuma reached its all-time high of 124 °F (51 °C).[16] The lowest recorded temperature was −6 °C (21 °F) on the Yuma-Mesa area in January 2007. The temperature fell to −6 °C (21 °F) for approximately two hours and harmed many crops grown in and around Yuma. The crop that suffered the most damage was the citrus on the Yuma mesa, most notably the lemon crop. It suffered a 75% to 95% loss of crop and trees, as stated by the Arizona Department of Agriculture in a February 2007 report. On average, the temperature lowers to the freezing mark in less than a quarter of years, and there are 118 days per year that reach or exceed 100 °F (38 °C), usually from April through October. During July and August the temperature fails to reach the century mark on at most, only a few days.
Phoenix, Arizona Phoenix has a hot desert climate (Köppen climate classification BWh),[10][11] typical of the Sonoran Desert. Phoenix has long, extremely hot summers and short, mild to warm winters. The city is located within the sunniest region in the world. Measuring 3,872 hours of bright sunshine annually, Phoenix receives the most sunshine of any major city on Earth.[88] Average high temperatures in summer are the hottest of any major city in the United States.[89] On average, there are 107 days annually with a high of at least 100 °F (38 °C)[90] including most days from late May through early October. Highs top 110 °F (43 °C) an average of 18 days during the year.[91] On June 26, 1990, the temperature reached an all-time recorded high of 122 °F (50 °C).[92] Despite the city's claim to the most extreme heat in summer, however, it does not have the highest average annual temperature in the contiguous United States. In that respect, it comes second to Miami; Phoenix has an average daily temperature of 75 °F (24 °C), compared to Miami's 77 °F (25 °C).[89]
