Weather in September
Temperature
With the commencement of September, Santa Elena records a moderate temperature decline, with the average high easing from August's very hot 100°F (37.8°C) to a hot 93°F (33.9°C). An average low-temperature of 77°F (25°C) is noted during the nights in September.Heat index
In September, the average heat index is evaluated at an extremely hot 109.4°F (43°C). Careful: Heat exhaustion and heat cramps are anticipated. With ongoing exertion, heatstroke becomes a possibility.Know that the heat index computations account for shaded terrains and slight winds. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
