Weather in July
Temperature
July's climate shows a minor adjustment in average high-temperatures to a still tropical 90.7°F (32.6°C) from June's 88.9°F (31.6°C). July generally records an average low-temperature of 78.4°F (25.8°C).Heat index
During July, the heat index is computed to be a blistering 111.2°F (44°C). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.Note that heat index values are valued for light wind and location in the shade. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Elevated relative humidity disrupts typical body cooling by reducing the evaporation rate, consequently decreasing the body's cooling rate and enhancing the feeling of heat. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
