Weather in July
July is a hot summer month in Yonaguni, Japan, with an average temperature varying between 31.4°C (88.5°F) and 26.6°C (79.9°F).
An excellent water temperature of 28.8°C (83.8°F) and 139mm (5.47") of accumulated rainfall makes July a prime for swimming and other water activities.
From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', determines the feeling of heat when you account for the relative humidity. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
Note: Temperatures between 25°C (77°F) and 29°C (84.2°F) are excellent for swimming, diving, and other water activities, providing comfort and enjoyment for extended periods without discomfort.
On the first day of the month, sunrise is at 06:03 and sunset at 19:40. On the last day of July, in Yonaguni, sunrise is at 06:16 and sunset at 19:32 JST.
