Weather in September
Temperature
As Secotan steps into September, the average high-temperature holds at a still tropical 87.4°F (30.8°C), hinting at a minor fluctuation from the prior month. Throughout September, the temperature falls to an average low of 71.8°F (22.1°C).Heat index
September's mean heat index is estimated at a very hot 102.2°F (39°C). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is the result of factoring in humidity to the air temperature, indicating perceived warmth. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. 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 highly critical to babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. The body is at risk of dehydration and related complications when it fails to shed excessive heat.

In Secotan, the average daily maximum UV index in September is 6. A UV Index reading of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV radiation for the ordinary person.Note: In September, the maximum UV index of 6 translates into these guidelines:
Undertake precautions and comply with sun safety standards. Protection from skin and eye injury is vital. The time between 10 a.m. and 4 p.m. is when UV radiation is at its peak. Limit exposure to direct sunlight during these hours. Tightly woven clothing, when worn loosely, shields effectively against the Sun.
