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

August's weather records an average high-temperature of a warm 85.3°F (29.6°C), showing little deviation from July. In the month of August, the average temperature dips to an enjoyable 66.2°F (19°C) during the night.

Heat index

During August, the heat index is estimated at a torrid 95°F (35°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', blends air temperature and moisture content to represent the felt temperature to humans. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children often overlook the need for breaks and fluid intake. Thirst is a late-stage sign of dehydration - hence, it is necessary to stay hydrated, especially during extended periods of physical activities.
Perspiration is the body's default response to elevated temperatures, as it promotes the evaporation of sweat to achieve 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. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
