Weather in July
Temperature
July registers as the month with the highest average temperatures, reaching 86.7°F (30.4°C) at its peak and 66.7°F (19.3°C) at the lowest.Heat index
Throughout July, the heat index is appraised at a fiery hot 98.6°F (37°C). Undertake special precautions, the probability of heat exhaustion and heat cramps is high. Prolonged activity may provoke heatstroke.Regarding the heat index, one should be aware it's determined by shaded settings and 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 'real feel', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
