Weather in September
Temperature
The onset of September marks an average high-temperature of a still hot 31.7°C (89.1°F), hardly differing from August's 32.1°C (89.8°F). Throughout the nights in September, an average low-temperature of 24.6°C (76.3°F) is noted in Ocos.Heat index
During September, the heat index is computed to be a blisteringly hot 41°C (105.8°F). Undertake extra safety actions, heat cramps and heat exhaustion are expected. Heatstroke may result from lengthy activity.Heat index data is primarily for areas with shade and subjected to light winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a calculated temperature value of how hot it feels when the moisture in the air is factored in. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Direct sunlight exposure should be noted as it has the potential to increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. 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. During conditions of high air temperature and humidity (high heat index), the body's ability to perspire is inhibited, increasing the sensation of warmth. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Embrace precautions and observe sun safety norms. Evasion of sunburn 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.
