Weather in August
Temperature
The average high-temperature is a still hot 86.9°F (30.5°C) in August, hardly different from the 87.8°F (31°C) recorded in July. An average temperature of 67.6°F (19.8°C) is recorded during the nights in August.Heat index
August's average heat index is estimated at a fiery hot 100.4°F (38°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.Observations indicate that the heat index values are for shady locations with light wind. The heat index might be elevated by 15 Fahrenheit (8 Celsius) degrees due to direct sun exposure.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
