Weather in July

July is a hot summer month in Koshigaya, Japan, with an average temperature fluctuating between 30.1°C (86.2°F) and 23.1°C (73.6°F).

Temperature

As June transitions into July, a subtle temperature shift is observed, with average highs adjusting from a moderately hot 26°C (78.8°F) to a tropical 30.1°C (86.2°F). During July, Koshigaya records a consistent average nighttime temperature of 23.1°C (73.6°F).

Heat index

July's mean heat index is computed to be a sweltering 37°C (98.6°F). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.
It is important to note that the heat index values are for shaded areas and light wind scenarios. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', blends air temperature and moisture content to represent the felt temperature to humans. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Consider the fact that direct sun exposure can influence how hot one feels, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Heat absorption that surpasses the body's shedding capability can lead to overheating and varying levels of dehydration.
