Weather in July
Temperature
July, with its high-temperature average of 89.6°F (32°C) and a low-temperature average of 69.4°F (20.8°C), is the warmest month.Heat index
July's mean heat index is calculated to be a blisteringly hot 105.8°F (41°C). Adopt extra preventive measures, the occurrence of heat cramps and heat exhaustion is likely. Heatstroke may follow extended activity.Be advised, the heat index considers values for conditions in shade and with a light breeze. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to babies and toddlers. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
