Weather in July
Temperature
The beginning of July records an average high-temperature of a still tropical 93.7°F (34.3°C), marking a negligible difference from June's 91.6°F (33.1°C). Vienna witnesses a consistent average low-temperature of 73°F (22.8°C) throughout July.Heat index
In July, the heat index is calculated to be a blazing hot 118.4°F (48°C). Be careful: Heat exhaustion and heat cramps are probable. Heatstroke may result from extended activity.Observations indicate that the heat index values are for shady locations with light wind. With direct sunlight, the heat index could increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', measures the perceived warmth when incorporating the humidity present in the air. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
Perspiration is essential for the human body; it facilitates cooling through the process of sweat evaporation. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

June through August, with an average maximum UV index of 7, are months with the highest UV index. A UV Index of 6 to 7 symbolizes a high health risk from exposure to the Sun's UV radiation for the average person.Note: The average daily UV index of 7 in July transforms into the following instructions:
Implement precautions and maintain sun safety methods. Avoidance of sunburn is demanded. Limit direct sun exposure and seek shade between 10 a.m. and 4 p.m., the time of the most intense UV radiation, noting that shade structures may not provide total sun protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes.
