Weather in September
Temperature
Sabana Grande transitions into September recording an average high-temperature of a still tropical 32.7°C (90.9°F), closely aligning with the preceding month's temperature. During September, an average low-temperature of 22.5°C (72.5°F) is observed.Heat index
September's mean heat index is evaluated at a scorching 43°C (109.4°F). Caution: Heat cramps along with heat exhaustion are expected. Sustained activity could lead to heatstroke.Factoring in the heat index, values are geared towards shaded areas with light breezes. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', combines both the air temperature and the humidity level to give a perceived human temperature. The influence of weather is personal, differing among individuals based on variations in body mass, stature, and the degree of physical exertion. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. When body heat isn't effectively managed, risks of dehydration and overheating amplify.

Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. Limit direct sun exposure especially between 10 a.m. and 4 p.m., when UV radiation is at its peak. However, keep in mind that shade structures may not provide full sun protection. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance.
