Weather in July
Temperature
July and August, with an average high-temperature of 94.6°F (34.8°C), are the warmest months.Heat index
July's mean heat index is evaluated at a blazing hot 122°F (50°C). Be on the lookout: Heat cramps and heat exhaustion are anticipated. Continued exertion can result in heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Excessive heat gain, when not shed effectively by the body, can result in increasing body temperatures and related hazards.
