Weather in September
Temperature
The start of September marks an average high-temperature of a still tropical 86.5°F (30.3°C), hardly distinguishable from the conditions in August. In September, Midnight records an average nighttime temperature of 67.5°F (19.7°C).Heat index
For most parts of September, the heat index is calculated to be a torrid 96.8°F (36°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Given the heat index, its values are aligned with shaded sites and gentle winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', is a fusion of air temperature and moisture levels to demonstrate the sensation of heat. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
By perspiring, the human body can shed its excessive warmth since evaporated sweat cools it off. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. If heat absorption exceeds the body's cooling ability, body temperature can elevate, resulting in potential thermal illnesses.

The months with the least rainfall are September and November Rain falls for 13 days and accumulates 2.2" (56mm) of rain.Snowfall

In Midnight, the average daily maximum UV index in September is 6. A UV Index of 6 to 7 symbolizes a high threat to health from unsafe exposure to UV radiation for the ordinary person.Note: A typical high UV index of 6 in September suggests the following recommendations:
Implement precautions and maintain sun safety methods. Avoidance of sunburn is demanded. The Sun's UV radiation is most powerful between 10 a.m. and 4 p.m. To the extent possible, limit exposure to the direct sun during these hours. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
