Weather in August
Temperature
The arrival of August records an average high-temperature of a still hot 88.3°F (31.3°C), closely related to the 89.6°F (32°C) observed in July. During August, the temperature tends to dip to an average of 67.6°F (19.8°C) at night.Heat index
The heat index in August is appraised at a torrid 102.2°F (39°C). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'apparent 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. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
To cool down, the human body relies on perspiration, a process where excessive heat is eliminated as sweat evaporates. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

Dodge overexposure. Fair-skinned people can get singed in less than 20 minutes. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. On days when the sun blazes, arm yourself with sunglasses that block UVA and UVB radiation.
