Temperature

August is the month when Nara's temperatures reach their peak, with averages of 32.6°C (90.7°F) and lows of 22.6°C (72.7°F).

Heat index

The average heat index in August is computed to be a blisteringly hot 44°C (111.2°F). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.
Remember that heat index calculations are made for conditions in the shade with light wind. With exposure to direct sunlight, the heat index may be increased by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. When heat gain surpasses the level the body can shed, body temperature begins to increase, and consequently, overheating and dehydration can occur, with varying severity.

Without adequate protection, skin and eyes might suffer damage. Ensure precautions are in place. It's important to stay in the shade and limit exposure to the sun from 10 a.m. to 4 p.m., when UV radiation is most intense, although remember that shade structures may not provide full sun protection. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat. After a swim or outdoor exercise, one should liberally reapply broad-spectrum sunscreen with a sun protection factor of 30 or higher.
