July weather forecast
Arizona, USA

July in Arizona can be described as the epicenter of the summer heat, with temperatures often reaching their peak values for the year. However, this month also introduces the monsoon season, bringing sporadic rain showers and thunderstorms to parts of the state.

Phoenix, along with other southern desert areas, grapples with blistering heat in July. Daytime temperatures frequently oscillate between 105°F (40.6°C) and 115°F (46.1°C), with some locations even witnessing temperatures exceeding the 120°F (48.9°C) mark. Nights provide minimal relief, with temperatures typically ranging from 80°F (26.7°C) to 90°F (32.2°C). The onset of the monsoon season means sporadic rain showers and thunderstorms become a possibility, albeit these are often brief and localized.

The northern highland regions, such as Flagstaff, also experience warm conditions, but they remain significantly cooler than the southern parts. Daytime temperatures in these areas tend to lie between 80°F (26.7°C) and 90°F (32.2°C). Nights are considerably more pleasant, with temperatures from 55°F (12.8°C) to 65°F (18.3°C). These regions too can experience occasional monsoon showers, which may bring temporary respite from the summer heat.

In comparison to June, July retains the intense heat but introduces an element of unpredictability with the advent of the monsoon season. As Arizona progresses into August, similar weather patterns can be anticipated, with monsoonal activity potentially becoming more pronounced.
