July weather forecast
Kagoshima, Japan

Although the rainfall slightly drops in July, Kagoshima remains warm and wet. The mercury still hovers around the same figures as June, keeping the temperatures on the higher side. The daylight duration remains nearly the same, providing ample sunlit hours. The UV index during this month is at its maximum, necessitating extra protection from the strong sun. The city experiences a high temperature reaching 31.9°C (89.4°F), which is the warmest for the year.

Temperature

In July, the meteorological conditions in Kagoshima subtly change with the average high-temperature edging from a warm 27.6°C (81.7°F) in June to a tropical 31.9°C (89.4°F). During the month of July, the temperature in Kagoshima generally drops to a low average of 25.3°C (77.5°F).

Heat index

July's mean heat index is calculated to be a blisteringly hot 42°C (107.6°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. When body temperature rises due to excess heat gain beyond its removal capability, one might experience heat-related disorders.

UV index

The months with the highest UV index in Kagoshima are June through August, with an average maximum UV index of 11. A UV Index estimate of 11, and higher, represents an excessive health risk from exposure to the Sun's UV radiation for the average person.
Note: The daily high UV index of 11 during July translates into the following recommendations:
Take all required precautions, as unprotected skin and eyes can burn in minutes. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized. One should apply and reapply liberally a broad-spectrum sunscreen of SPF 30+ every two hours and immediately after a swim or an outdoor exercise. Be vigilant! The Sun's UV rays get a boost from sand and water reflections.
