Weather in July

Delta's weather in July is characterized by its peak summer conditions with temperatures that can reach up to 91.8°F (33.2°C). The heat, coupled with relatively high humidity levels, can make the outdoor conditions quite stifling. In addition, July has the longest daylight duration, providing 14 hours of daylight. The absence of snow and a stable visibility of 6 miles point towards consistently sunny and clear weather. The sweltering temperatures usually continue into the next month, so residents should expect more of the same in August.

Temperature

July is the month when Delta's temperatures reach their peak, with averages of 91.8°F (33.2°C) and lows of 72.7°F (22.6°C).

Heat index

In July, the heat index is computed to be a life-threatening hot 114.8°F (46°C). Remain alert: Heat exhaustion and heat cramps are predicted. Extended effort can lead to heatstroke.
Heat index values are typically calculated for conditions of shade and a light breeze. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', integrates the air's temperature and its humidity to showcase the felt temperature by people. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Children often overlook the necessity for resting and fluid replenishment. Thirst is a late sign of dehydration - thus, it is critical to stay hydrated, especially during extended periods of physical activities.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Also note that objects like parasols or canopies might not provide complete sun protection. Opt for tightly woven and loose clothing to enhance protection from the Sun.
