Weather in September
Temperature
As Barrancas transitions from August to September, the average high-temperatures adjust to a hot 30.3°C (86.5°F), nearly the same as the previous 29.4°C (84.9°F). Barrancas, in September, experiences an average temperature of 19.8°C (67.6°F) at night.Heat index
For September, the heat index is evaluated at a fiery hot 35°C (95°F). Ensure heightened precautions, risk of heat cramps and heat exhaustion is significant. Sustained activity could provoke heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The influence of weather can be personal, changing with an individual's body mass, height, and level of physical exertion. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.
