Weather in July

July, the same as June, is another warm summer month in Fukue Island, Japan, with temperature in the range of an average low of 23.4°C (74.1°F) and an average high of 29.3°C (84.7°F).

Temperature

The onset of July brings a minor temperature shift, with the average high-temperature moving from a moderately hot 25.6°C (78.1°F) in June to a still warm 29.3°C (84.7°F). Nighttime temperatures consistently average a still warm 23.4°C (74.1°F) during July.

Heat index

For July, the heat index is computed to be a very hot 37°C (98.6°F). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.
Realize that the values for the heat index are set for shaded places and light winds. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', quantifies the warmth felt when relative humidity is considered. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
The innate cooling system of the human body revolves around perspiration, with the evaporation of sweat being central to this process. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.
