Weather in September
Temperature
With the onset of September, Kashiwa's average high-temperature slightly adjusts, moderately receding from August's tropical 31.5°C (88.7°F) to a moderately hot 27.2°C (81°F). September nights cool down to an average low-temperature of 20.7°C (69.3°F).Heat index
For September, the heat index is computed to be a tropical 30°C (86°F). Exposure and extended activity could potentially cause a state of fatigue and lead to heat cramps.Note that heat index values are valued for light wind and location in the shade. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
