Weather in September
Temperature
The advent of September brings a slight shift in average high-temperature, moving from a sweltering 98.2°F (36.8°C) in August to a tropical 92.5°F (33.6°C). During September, Delmita experiences a consistent low-temperature average of 77.2°F (25.1°C).Heat index
In September, the heat index is appraised at a blisteringly hot 109.4°F (43°C). Keep on guard: Heat exhaustion and heat cramps are probable. Heatstroke is a possible danger with ongoing physical activity.Know that the heat index computations account for shaded terrains and slight winds. When exposed to the direct sun, the heat index may augment by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is a measure that combines air temperature and relative humidity into a single value that indicates how hot the weather feels. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. You should know that direct sun exposure can heighten weather effects, potentially elevating the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical 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 is essential for the human body; it facilitates cooling through the process of sweat evaporation. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. When the body is unable to balance heat gain, its temperature elevates, which may induce thermal illnesses.

Evade overexposure. Individuals with fair skin risk burning in under 20 minutes. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
