Weather in August
Temperature
The transition into August shows a subtle variation to a warm 85.5°F (29.7°C) from July's 87.6°F (30.9°C) in the average high-temperature. An average low-temperature of 64.6°F (18.1°C) is recorded during the nights in August.Heat index
For most parts of August, the heat index is computed to be a fiery hot 95°F (35°C). Take more preventive steps, risk of heat exhaustion and heat cramps is elevated. Long activity may culminate in heatstroke.Heat index data is primarily for areas with shade and subjected to light winds. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. A person's impression of weather can be affected by numerous aspects, among them metabolic variations, pregnancy, and activity levels. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for babies and toddlers. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.
