Weather in August
Temperature
August's advent notes a subtle adjustment in average high-temperature to a still hot 90.1°F (32.3°C) from July. During August, the nighttime temperature averages to an agreeable 73.2°F (22.9°C).Heat index
August's mean heat index is estimated at a blisteringly hot 111.2°F (44°C). Keep wary: Heat cramps along with heat exhaustion are expected. Heatstroke is a possible outcome of ongoing activity.The heat index's values are generally associated with conditions in shade and light breezes. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. 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. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. With excessive moisture in the atmosphere, the effectiveness of the evaporation process is decreased, causing the body to cool down less efficiently, leading to a sensation of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Act on precautions and pay attention to sun safety recommendations. Avoidance of sunburn is obligatory. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. Fend off the sun's harsh rays with appropriate clothing, a wide-brim hat, and UV-protective sunglasses.
