Weather in September
Temperature
The ushering in of September brings an average high-temperature of a still tropical 87.8°F (31°C), closely mirroring the 92.3°F (33.5°C) of August. Lunita experiences a consistent average temperature of 71.2°F (21.8°C) throughout the nights in September.Heat index
For September, the heat index is evaluated at a scorching 104°F (40°C). Take extra precautions, as heat cramps and heat exhaustion are possible. Sustained activity may result in heatstroke.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. 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 particularly relevant to children. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
The body's self-cooling mechanism is rooted in perspiration, where evaporating sweat cools down excessive warmth. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.

Sunshine
In September, the average sunshine is 9.6h.UV index
In September, the average daily maximum UV index is 6. A UV Index estimate of 6 to 7 represents a high health hazard from exposure to the Sun's UV radiation for the average person.Note: In September, a regular UV index of 6 translates into these guidelines:
Escape overexposure. People with light skin may incur burns in fewer than 20 minutes. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. For minimizing sun-related eye damage, always choose sunglasses with UVA and UVB coverage. Consider this! The reflection from snow can almost double the intensity of the Sun's UV radiation.
