Weather in September
Temperature
Barranco's shift into September is marked by a subtle change to a still hot 32.4°C (90.3°F) from August's 31.8°C (89.2°F) in temperature. With a significant temperature contrast, nighttime temperatures hover around an average low of 20.3°C (68.5°F) in September.Heat index
For September, the heat index is calculated to be a blistering 42°C (107.6°F). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Know that the heat index computations account for shaded terrains and slight winds. The heat index may experience an enhancement of 15 Fahrenheit (8 Celsius) degrees under direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', binds temperature metrics with humidity values to give a sense of the actual warmth. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. It is noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
Evaporating sweat, an outcome of perspiration, is key in assisting the human body to moderate its temperature. An increase in relative humidity disrupts body cooling by slowing the evaporation rate, thereby reducing the rate at which the body cools and amplifying the sense of heat. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

A UV Index reading of 6 to 7 represents a high health risk from unsafe exposure to UV radiation for ordinary individuals.Note: A daily maximum UV index of 7 in September translates into the following instructions:
Deflect overexposure. Sun protection is a necessity. Avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is most intense, and remember that not all shade structures provide full protection. Always opt for UVA and UVB-resistant sunglasses on radiant days.
