Weather in September
Temperature
Vespasiano witnesses its highest temperatures in September and October, reaching an average of 27.5°C (81.5°F).Heat index
During September, the heat index is appraised at 29°C (84.2°F). Exhaustion becomes probable with enduring exposure and activity, potentially causing heat cramps.Heat index guidelines indicate values are for light wind scenarios and shaded regions. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'feels like', binds temperature metrics with humidity values to give a sense of the actual warmth. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Being aware that direct sunlight can impact the felt heat might mean an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.

Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Seek shade and minimize exposure to direct Sun in a period between 10 a.m. and 4 p.m. when UV radiation is most intense; keep in mind that shade structures like parasols or canopies do not provide perfect sun protection. Employ a wide-brim hat for potent defense against up to 50% of UV rays.
