Weather in September
Temperature
The onset of September brings a small change in high-temperatures, falling from a tropical 34.4°C (93.9°F) in August to a warm 28.5°C (83.3°F). Yubei experiences a mean temperature of 21.3°C (70.3°F) during September nights.Heat index
In September, the average heat index is estimated at a tropical 32°C (89.6°F). If one remains active during constant exposure, it might cause exhaustion and heat cramps.Remember that heat index calculations are made for conditions in the shade with light wind. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', marries air temperature and humidity to produce a value illustrating perceived warmth. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. Stay out of direct sunlight between 10 a.m. and 4 p.m., when UV radiation is most intense, and remember that not all shade structures provide complete protection. Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears.
