Weather in August
Temperature
The yearly peak temperatures occur in July and August, averaging a high-temperature of 89.2°F (31.8°C).Heat index
The heat index in August is evaluated at a blisteringly hot 105.8°F (41°C). Undertake additional precautions, heat cramps and heat exhaustion could happen. Heatstroke could occur from sustained activity.When assessing, remember that heat index measurements are for light winds and shaded spots. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones are generally more prone to risk than adults due to their reduced ability to sweat. Their large skin surface area relative to their diminutive bodies and elevated heat production from their activities further enhance this risk.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. 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. As the body gains more heat than it can dissipate, there's a risk of increasing temperatures and resultant overheating.
