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
The heat index for July is computed to be a blazing hot 118.4°F (48°C). Stay alert: Heat cramps and heat exhaustion are expected. Heatstroke is a likely outcome of ongoing activity.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'real feel' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. When there is an excess of moisture in the atmosphere, the efficiency of the evaporation process is lessened, leading to less efficient body cooling and a sensation of overheating. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.

Fend off overexposure. Sun protection is vital. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. A wide-brimmed hat is a staple for defending the face, eyes, ears, and neck from the Sun.
