Weather in August
Temperature
In August, the average high-temperature registers at a still hot 90.1°F (32.3°C), nearly identical to July's 90.7°F (32.6°C). Throughout August, Arno records an average temperature of 75°F (23.9°C) at night.Heat index
August's mean heat index is estimated at a burning hot 113°F (45°C). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.Observations indicate that the heat index values are for shady locations with light wind. The heat index may scale up by 15 Fahrenheit (8 Celsius) degrees with direct sun exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', evaluates the perceived heat by adding the effect of moisture in the air. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.
Humidity
The months with the highest humidity are August and September, with an average relative humidity of 78%.Rainfall
The wettest months in Arno are July and August, with an average 2.09" (53mm) of rainfall.Daylight

Sunshine

The months with the highest UV index in Arno are May through August, with an average maximum UV index of 7. A UV Index value of 6 to 7 symbolizes a high health risk from unprotected exposure to Sun's UV rays for the average person.Note: In August, a daily maximum UV index of 7 leads to the following instructions:
Incorporate safeguards and honour sun safety principles. Protection from skin and eye damage is obligatory. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
