Weather in September
Temperature
September brings a marginal elevation to a still tropical 87.1°F (30.6°C) from August's 90.9°F (32.7°C) in Lum's average high-temperatures. In September, the average low-temperature records at an enjoyable 67.6°F (19.8°C) during the nights.Heat index
The heat index for September is appraised at a sweltering 100.4°F (38°C). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.Heat index guidelines indicate values are for light wind scenarios and shaded regions. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. The sun, when shining directly, can have a significant impact on the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. 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.
Perspiration is the human body's physiological response to high temperatures and is an attempt to lower body temperature through evaporation of sweat. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
