Weather in September
Temperature
The dawn of September sees an average high-temperature of a still moderately hot 29.4°C (84.9°F), subtly contrasting with August's 29.6°C (85.3°F). During September, the nighttime temperatures align closely with the daytime averages, measuring a still warm 25.3°C (77.5°F).Heat index
The average heat index in September is evaluated at a torrid 36°C (96.8°F). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Know that the heat index computations account for shaded terrains and slight winds. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'real feel' or 'apparent temperature', gauges the sensation of temperature factoring in the air's moisture content. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Resist overexposure. Safeguarding from solar damage is indispensable. Between 10 a.m. and 4 p.m., UV radiation is strongest. Make an effort to avoid direct sunlight during this time, remembering that shade structures may not provide full sun protection. Shield yourself from the harmful effects of UV radiation with sun-protective attire, a hat, and quality sunglasses.
