August weather forecast
Oita, Japan

August retains July's heat, with similar high temperatures. It marks the culmination of the summer season, with the last bouts of intense rainfall. Following July's peak, rainfall starts to decline, yet humidity levels remain high. The sea temperature touches its peak, offering the perfect conditions for a dip in the sea. The shift towards September implies a decrease in both temperatures and rainfall levels, as Oita heads towards the fall season.

Temperature

In Oita, temperatures reach their average annual highs in August, measuring 30°C (86°F) and a minimum average of 23.4°C (74.1°F).

Heat index

August's heat index is evaluated at a sweltering 38°C (100.4°F). Implement more preventive measures, heat cramps and heat exhaustion are probable. Heatstroke might result from extended activity.
It is essential to grasp that the heat index's numbers are for shade and light wind settings. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. Elevated relative humidity diminishes evaporation, thereby reducing the body's ability to shed heat and creating a feeling of being too warm. 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.

Guard against overexposure. Protection from sun-induced harm is essential. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. A hat with a broad brim is indispensable, filtering out up to half of UV rays. Caution! Sand and water surfaces escalate the UV intensity from the Sun.
