Weather in September
Temperature
The advent of September signifies a minor shift to an average high-temperature of a still tropical 30.9°C (87.6°F), aligning closely with August. Manuel Tames's temperature in September lowers to a consistent average of 23.5°C (74.3°F) during the nights.Heat index
The heat index in September is calculated to be a blistering 40°C (104°F). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.It is noted that heat index values are ascertained for locations in the shade and with gentle breezes. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. The effect of weather is individual, with a variety of people experiencing it differently due to distinctions in body mass, height, and level of activity. 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 hold particular importance for children. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
Perspiration, followed by sweat evaporation, is the human body's chief method to maintain a balanced temperature. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Overheating can ensue when the body accumulates more heat than it can release, and dehydration severity may vary.

Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. Avoid direct Sun exposure and seek shade from 10 a.m. to 4 p.m., the period of highest UV radiation. Remember, however, that not all shade structures offer full protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
