Weather in August
Temperature
The onset of August brings an average high-temperature of a still warm 81.9°F (27.7°C), nearly matching the July temperature. An average nighttime temperature of 61°F (16.1°C) is noted during the month of August.Heat index
August's mean heat index is calculated to be a hot 87.8°F (31°C). If activity and exposure persist, they could induce fatigue, leading to possible heat cramps.Keep in mind the heat index values are meant for areas in shade and with light wind. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Awareness is key; direct sunlight can enhance the weather's impact, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
