Weather in September
Temperature
Lowlands greets September with an average high-temperature of a still tropical 86.7°F (30.4°C), marking a slight deviation from the preceding month. Lowlands reports an average low-temperature of 72.1°F (22.3°C) during the nights of September.Heat index
For September, the heat index is estimated at a sweltering 102.2°F (39°C). Take more safety measures, heat exhaustion and heat cramps are potential outcomes. Persistent activity might lead to heatstroke.Heat index determinations are made taking into account the shade and light air movements. 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 'real feel', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Juveniles are regularly less conscious of the need to recuperate and rehydrate. Thirst is a tardy symptom of dehydration - hydration, especially during lengthy physical activities, should be maintained.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Boost your sun resistance with garments that are densely woven yet spacious.
