Weather in September
Temperature
September's beginning signals an average high-temperature of a still hot 88.3°F, barely different from August's 86.9°F. The average low-temperature of 72.7°F is witnessed during September.Heat index
Throughout September, the heat index is calculated to be a sweltering 100.4°F. Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.Heat index values are typically calculated for conditions of shade and a light breeze. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is an estimation of the warmth sensation when considering humidity levels. Metabolic differences, pregnancy status, and the level of physical activity are additional factors influencing an individual's weather perception. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for 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.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Stay clear of intense sun exposure. Solar protection is of utmost significance. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation.
