Temperature

During the warmest month, August, temperatures average a high of 95.5°F (35.3°C) and a low of 75.6°F (24.2°C).

Heat index

August's mean heat index is evaluated at a blisteringly hot 111.2°F (44°C). Stay mindful: Heat exhaustion and heat cramps are likely. Heatstroke could follow extended physical effort.
Understanding the heat index involves considering values for shaded locales with light wind. 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 'apparent temperature', combines both the air temperature and the humidity level to give a perceived human temperature. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
