Weather in July
Temperature
July's climate shows a minor adjustment in average high-temperatures to a still tropical 86.5°F (30.3°C) from June's 90.1°F (32.3°C). Sierra Vista observes an average low-temperature of 69.6°F (20.9°C) during July nights.Heat index
During July, the heat index is estimated at a tropical 87.8°F (31°C). Exhaustion becomes probable with enduring exposure and activity, potentially causing heat cramps.Observations indicate that the heat index values are for shady locations with light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
