Weather in August
Temperature
The average high-temperature is a still hot 87.6°F (30.9°C) in August, hardly different from the 88.2°F (31.2°C) recorded in July. An average temperature of 68.5°F (20.3°C) marks the nights in August.Heat index
The heat index value during August is estimated at a torrid 102.2°F (39°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. 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 highly critical for babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Overheating dangers loom when the body's heat release mechanisms are overshadowed by excessive gain.
