Weather in August
Temperature
The commencement of August introduces an average high-temperature of a still hot 89.6°F (32°C), closely mirroring the preceding month. Throughout August, an average low-temperature of 70.7°F (21.5°C) is experienced.Heat index
In August, the heat index is computed to be a scorching 105.8°F (41°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.The heat index's values are generally associated with conditions in shade and light breezes. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', gives an indication of how one might feel in terms of heat after considering humidity. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. 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 hold particular importance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
