Weather in July
Temperature
July, marked by an average high-temperature of 81.9°F (27.7°C) and a low-temperature of 66.6°F (19.2°C), is the warmest month.Heat index
During July, the heat index is calculated to be a hot 87.8°F (31°C). Continuous exposure and activity could induce a sense of tiredness and subsequently, heat cramps.It is emphasized that the heat index's values are meant for shaded zones with mild winds. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to 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.
