Temperature

July, with average temperatures reaching a high of 86.5°F (30.3°C) and a low of 65.5°F (18.6°C), is the warmest month.

Heat index

The heat index value for July is evaluated at a torrid 98.6°F (37°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. An individual's temperature experience can be influenced by extra factors, including metabolic differences, activity levels, and clothing. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Young ones generally face higher dangers than adults since they sweat less. Along with their large skin surface area compared totheir small bodies and increased heat production from their activities, the risks are heightened.
The body's inherent cooling system operates through perspiration, wherein evaporating sweat offsets excessive heat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
