Weather in August
Temperature
Iroquois's average high-temperature in August sits at a still warm 84.2°F (29°C), showing little difference from the previous month. Throughout August, Iroquois notes a dramatic plunge from the daily high to an average low-temperature of 61.3°F (16.3°C).Heat index
Throughout August, the heat index is evaluated at a hot 89.6°F (32°C). Uninterrupted exposure and activity might result in fatigue, potentially causing heat cramps.Note that heat index values are valued for light wind and location in the shade. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
