Weather in July
Temperature
Dart records the warmest temperatures in July, averaging a high of 89.4°F (31.9°C) and a low of 69.4°F (20.8°C).Heat index
July's mean heat index is evaluated at a blisteringly hot 107.6°F (42°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children frequently do not understand the need for recuperation and hydration. Thirst, being a late manifestation of dehydration, underlines the need to hydrate frequently, especially when engaging in prolonged physical exercises.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

May through August, with an average maximum UV index of 6, are months with the highest UV index. A UV Index reading of 6 to 7 represents a high health hazard from unsafe exposure to UV radiation for ordinary individuals.Note: The maximum UV index of 6 during July leads to these instructions:
Undertake protective measures and comply with sun safety rules. Shielding against skin and eye damage is essential. During the period from 10 a.m. to 4 p.m., UV radiation is highest. Try to avoid direct sunlight during these hours. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
