Weather in July
Temperature
July, recording an average high temperature of 90°F (32.2°C) and a low temperature of 69.3°F (20.7°C), is Callahans Corner's warmest month.Heat index
During July, the heat index is computed to be an extremely hot 105.8°F (41°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.For clarity, heat index numbers account for light winds and areas under shade. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. 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 remain especially vital for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
The human body normally cools itself by perspiration, as evaporated sweat carries heat away from the body. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
