Weather in August
Following on the heels of the hottest month, August sees a slight drop in temperatures. While still part of the summer season, the weather begins to show signs of an approaching transition to fall. Although the temperatures are similar to July, there's a noticeable reduction in the average daylight hours. Despite this, August still enjoys plenty of sunshine and warmth. The weather conditions during August provide the city with a golden hue under the sunlight due to the retained heat from July.Temperature
The shift to August signals an average high-temperature of a warm 85.3°F (29.6°C), subtly varied from July's 87.4°F (30.8°C). During the August nights, an average temperature of 66.2°F (19°C) is observed.Heat index
In August, the heat index is computed to be a torrid 95°F (35°C). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.Take into consideration that the heat index values are calculated for shade and light wind conditions. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
