July, on average, is the warmest month, registering a high temperature of 89.2°F (31.8°C) and a low of 69.4°F (20.8°C).Heat index
July's heat index is calculated to be a blisteringly hot 105.8°F (41°C). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.Heat index readings emphasize conditions of light breezes and shaded spots. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
