Weather in September
Temperature
The weather during September records an average high-temperature of a still tropical 88.2°F (31.2°C), closely mirroring the preceding month. September nights experience a consistent temperature drop to an agreeable 68.9°F (20.5°C).Heat index
The heat index for September is calculated to be a blistering 104°F (40°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. When under direct sunshine, the heat index may be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', quantifies the warmth felt when relative humidity is considered. This effect is personal, influenced by the individual's physical activity and heat sensitivity, shaped by factors including wind, attire, and metabolic variations. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young individuals usually face more risks than adults due to their lower sweat production. Their large skin surface area relative to their tiny bodies and high heat production from their activities adds to their risk.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.

Stick with precautions and abide by sun safety procedures. Evading sunburn is essential. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Employ a hat with a wide brim for robust protection, cutting UV exposure by half.
