Weather in September
Temperature
Logo marks the start of September with an average high-temperature of a still tropical 31.1°C (88°F), hinting at a slight fluctuation from August's 30.1°C (86.2°F). The temperature dips to an average of 19.5°C (67.1°F) during September nights.Heat index
In September, the average heat index is appraised at a fiery hot 38°C (100.4°F). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. Direct sunlight might lead to a heat index increase by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', combines both the air temperature and the humidity level to give a perceived human temperature. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. In the direct sunlight, the weather's impact can be amplified, possibly boosting the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. Greater relative humidity lessens the rate of evaporation, thus decreasing the body's heat dispersal, which gives rise to a sensation of overheating. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

April through November, with an average maximum UV index of 6, are months with the lowest UV index. A UV Index value of 6 to 7 symbolizes a high threat to health from exposure to the Sun's UV rays for average individuals.Note: A maximum UV index of 6 in September translates into the following recommendations:
Use measures and accept sun safety conventions. Guarding against skin and eye trauma is of high priority. 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. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
