Weather in September
Temperature
The transition to September results in a modest reduction in average high-temperature, moving from a hot 94.6°F (34.8°C) in August to a still tropical 88.5°F (31.4°C). In September, Joinerville experiences a temperature dip to an average of 67.6°F (19.8°C) at night.Heat index
In September, the average heat index is computed to be a fiery hot 102.2°F (39°C). Ensure extra safety measures, heat exhaustion and heat cramps are likely. Continuous activity might result in heatstroke.It is essential to grasp that the heat index's numbers are for shade and light wind settings. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. When relative humidity is at high levels, the evaporation rate lessens, causing the body to keep more heat than it would in less humid conditions. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
