Weather in July
Temperature
Jefferson's temperatures peak on average in July, reaching 92.8°F (33.8°C) at their highest and 72.7°F (22.6°C) at their lowest.Heat index
In July, the heat index is estimated at a blazing hot 118.4°F (48°C). Mindful: Heat cramps and heat exhaustion are to be expected. Extended physical effort might result in heatstroke.In the scope of the heat index, its values resonate with shade and light wind conditions. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. Under conditions of high temperature and humidity (enhanced heat index), sweat production is compromised, exacerbating the sensation of warmth. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
