Weather in September
Temperature
September is characterized by a slight reduction in average high-temperature, easing from a hot 93.7°F (34.3°C) in August to a still tropical 88°F (31.1°C). Bernice encounters an average low-temperature of 66.7°F (19.3°C) during September nights.Heat index
The heat index value during September is estimated at a torrid 100.4°F (38°C). Exercise special caution, heat exhaustion and heat cramps are probable. Prolonged activity may induce heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. By being directly under the sun, it's possible for the felt temperature to increase by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital 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.
One of the main methods the human body employs to cool down is by perspiring, as this process allows sweat to evaporate and remove excess heat. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Accumulating more heat than the body can dissipate leads to an uptick in body temperature, with potential heat stress consequences.
Humidity
July through October, with an average relative humidity of 71%, are the least humid months.Rainfall
The month with the least rainfall is September, when the rain falls for 13.5 days and typically collects 1.93" (49mm) of precipitation.Snowfall

Sunshine
In September, the average sunshine is 9.6h.UV index
In September, the average daily maximum UV index is 6. A UV Index reading of 6 to 7 represents a high threat to health from exposure to the Sun's UV radiation for ordinary individuals.Note: The maximum daily UV index, 6 in September, converts into the following recommendations:
Persist with precautions and heed sun safety advice. Prevention of sunburn is compulsory. Try to minimize direct Sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Also note that objects like parasols or canopies might not provide complete sun protection. Sunglasses providing both UVA and UVB protection are non-negotiable on sunlit days.
