Weather in July
Temperature
The month of July sees the highest average temperatures, reaching 90.3°F (32.4°C) at the peak and 69.8°F (21°C) at the low.Heat index
July's average heat index is calculated to be a scorching 105.8°F (41°C). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. 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.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
