Weather in September
Temperature
With the onset of September, a modest change to a still tropical 30.3°C (86.5°F) from August's 30.5°C (86.9°F) is noted in high-temperature. El Naranjo observes an average low-temperature of 23.2°C (73.8°F) during September nights.Heat index
The average heat index in September is evaluated at a fiery hot 39°C (102.2°F). Exercise enhanced safety steps, heat cramps and heat exhaustion are probable. Heatstroke could be a result of sustained activity.Take into consideration that the heat index values are calculated for shade and light wind conditions. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. 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 largely significant for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Deflect overexposure. Sun protection is a necessity. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage.
