Weather in September

September, the first month of the autumn in Lono, is still a warm month, with an average temperature fluctuating between 85.5°F (29.7°C) and 64.8°F (18.2°C).

Temperature

The average high-temperature slightly decreases in September, shifting from a tropical 91.4°F (33°C) in August to a moderately hot 85.5°F (29.7°C). Lono, in September, witnesses an average low-temperature of 64.8°F (18.2°C).

Heat index

The average heat index in September is evaluated at a sweltering 95°F (35°C). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.
When assessing, remember that heat index measurements are for light winds and shaded spots. Heat index values might soar by up to 15 Fahrenheit (8 Celsius) degrees with exposure to direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via 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. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
