Weather in September
Temperature
A minor adjustment in Kalona's average high-temperature is noted with the start of September, touching a still hot 86°F (30°C) from August's 90.1°F (32.3°C). During the month of September, the temperature falls to an average of 66.7°F (19.3°C).Heat index
For September, the heat index is estimated at a torrid 96.8°F (36°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.When assessing, remember that heat index measurements are for light winds and shaded spots. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', integrates the air's temperature and its humidity to showcase the felt temperature by people. 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. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
