Weather in July

The heat index value during July is calculated to be a hot 86°F (30°C). Persistently participating in activities during exposure may lead to fatigue and induce heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.

This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including 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 hold particular importance for children.

Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
