Weather in September
Temperature
The shift into September uncovers an average high-temperature of a still tropical 87.4°F (30.8°C), subtly different from the previous month. In the month of September, Lucas experiences an average low-temperature of 67.8°F (19.9°C).Heat index
For September, the heat index is computed to be a sweltering 102.2°F (39°C). Apply extra caution, heat cramps and heat exhaustion could happen. Heatstroke might occur with long-duration activity.Be informed that the heat index values are oriented around shady conditions and gentle breezes. The direct sun can potentially cause the heat index to increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', takes into account both air temperature and humidity to illustrate what people actually feel. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. 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.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Take heed. Individuals of lighter complexion can be burned in less than half an hour. The mid-day Sun emits the most powerful UV radiation, so seek shade and minimize exposure. A wide-brimmed hat is a shield, deflecting up to 50% of harmful UV radiation from eyes.
