Weather in September
Temperature
Boiling Point registers an average high-temperature of a warm 84.9°F (29.4°C) with the arrival of September, showing minor deviation from the preceding month. In September, Boiling Point endures a notable temperature shift from day to night, with lows averaging at a refreshing 60.3°F (15.7°C).Heat index
September's mean heat index is evaluated at 84.2°F (29°C). Extended exposure and activity might lead to tiredness, potentially resulting in heat cramps.Heat index details are generally centered around shaded locations and a mild breeze. An exposure to direct sunlight may lift the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', evaluates the perceived heat by adding the effect of moisture in the air. Additional elements encompassing metabolic differences, the degree of physical activity, and attire can impact the individual's perception of temperature. Direct exposure to sun rays can potentially augment the heat sensation, elevating the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.

Shun overexposure. Protection from sun ravages is indispensable. 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. A wide-brim hat offers excellent sun protection for the eyes, ears, face, and neck. Sunglasses with UVA and UVB protection significantly reduce eye damage from sun exposure.
