Weather in July
Temperature
O'Donnell notes an average high-temperature of a still hot 92.8°F (33.8°C) in July, displaying minor variation from June. O'Donnell sees an average low-temperature of 73.2°F (22.9°C) during July.Heat index
The heat index value during July is estimated at a sweltering 98.6°F (37°C). Implement additional cautionary measures, heat cramps and heat exhaustion could occur. Prolonged activity might induce heatstroke.For clarity, heat index numbers account for light winds and areas under shade. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. In the presence of high relative humidity, the evaporation rate diminishes, resulting in the body retaining more warmth compared to dry conditions. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.

Shield from overexposure. Defense against sun-related harm is required. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. A hat with a broad brim is indispensable, filtering out up to half of UV rays.
