Weather in July
Temperature
Union's temperature records reveal July as the warmest month, marked by average highs of 91.4°F (33°C) and lows of 71.2°F (21.8°C).Heat index
July's heat index is computed to be a blazing hot 114.8°F (46°C). Precaution: Heat cramps along with heat exhaustion are possible. Heatstroke is a serious risk with continued exertion.It is important to note that the heat index values are for shaded areas and light wind scenarios. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is found by incorporating humidity levels into the air temperature measurement. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
