Weather in July
Temperature
July is the warmest month, exhibiting average temperatures of 90.3°F (32.4°C) at the peak and 74.1°F (23.4°C) at the base.Heat index
July's heat index is appraised at a burning hot 113°F (45°C). Stay watchful: Heat exhaustion along with heat cramps are likely. Ongoing effort may cause heatstroke.Heat index determinations are made taking into account the shade and light air movements. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to 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.
Perspiring is how the human body naturally cools down, as sweat's evaporation takes away excess heat. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. The body is at risk of dehydration and related complications when it fails to shed excessive heat.
