Weather in August
Temperature
The average high-temperature is a still warm 80.8°F (27.1°C) in August, hardly different from the 82°F (27.8°C) recorded in July. Blackstone witnesses a consistent average low-temperature of 61.5°F (16.4°C) throughout August.Heat index
The heat index value during August is computed to be a tropical 86°F (30°C). Enduring exposure and unrelenting activity might cause a state of weariness, potentially leading to heat cramps.Be informed that the heat index values are oriented around shady conditions and gentle breezes. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gauges the sensation of temperature factoring in the air's moisture content. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. 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 quite important for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
