Weather in August
Temperature
The onset of August marks an average high-temperature of a warm 85.5°F (29.7°C), hardly differing from July's 87.3°F (30.7°C). In August, Ruma reports a consistent average low-temperature of 66°F (18.9°C) during the nights.Heat index
The average heat index in August is computed to be a fiery hot 96.8°F (36°C). Emphasize additional safety, risk of heat cramps and heat exhaustion is high. Continuous activity might result in heatstroke.Observations indicate that the heat index values are for shady locations with light wind. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'real feel' or 'felt air temperature', offers an insight into how hot it feels when we factor in moisture content. A person's impression of weather can be shaped by many aspects, among them metabolic variations, pregnancy, and levels of physical activity. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Young ones regularly neglect the requirement for rest and fluid replenishment. Thirst is a late stage of dehydration - so, it is necessary to keep hydrated, particularly during extended periods of physical exertion.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.

In August, the rain falls for 13.7 days. Throughout August, 2.6" (66mm) of precipitation is accumulated. Throughout the year, there are 138.9 rainfall days, and 26.81" (681mm) of precipitation is accumulated.Snowfall

Sunshine
In August, the average sunshine is 10.2h.UV index
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 exposure to the Sun's UV radiation for average individuals.Note: In August, the maximum UV index of 6 suggests this advice:
Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. Seek shade and limit direct Sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its peak, but be aware that not all shade structures provide complete sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
