Weather in September
Temperature
The weather during September records an average high-temperature of a fiery hot 36.5°C (97.7°F), closely mirroring the preceding month. An average low-temperature of 26.8°C (80.2°F) is observed during September nights.Heat index
September's heat index is appraised at an extremely hot 43°C (109.4°F). Heed: Expect heat cramps and heat exhaustion. Continued action may cause heatstroke.Know that the heat index computations account for shaded terrains and slight winds. Being under direct sunlight might amplify the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are extremely 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.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. In the presence of abundant moisture in the atmosphere, the cooling process through evaporation is hindered, causing the body to feel excessively warm. When heat gain exceeds the level the body can remove, body temperature begins to rise, and heat-related illnesses and disorders may develop.

Prioritize your safety. Without precautions, skin and eyes might get hurt quickly. 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 providing both UVA and UVB protection are non-negotiable on sunlit days.
