Weather in September
Temperature
Ensanche Quisqueya experiences an average high-temperature of a still tropical 30.3°C (86.5°F) in September, subtly different from August's 30.5°C (86.9°F). During September, Ensanche Quisqueya witnesses a consistent average low-temperature of 23.2°C (73.8°F).Heat index
In September, the average heat index is calculated to be a fiery hot 39°C (102.2°F). Extra safeguards are necessary to prevent heat exhaustion and heat cramps. Prolonged activity might cause heatstroke.It is important to note that the heat index values are for shaded areas and light wind scenarios. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', joins air temperature with relative humidity to produce a temperature perception for humans. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
Normally, the human body cools itself through perspiration, which removes excessive heat by evaporating sweat. An upsurge in relative humidity affects normal body cooling mechanisms 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.
