Weather in September
Temperature
September's presence marks an average high-temperature of a still tropical 86.7°F (30.4°C), subtly varied from August's 89.2°F (31.8°C). During September, the temperature tends to dip to an average of 75.9°F (24.4°C) at night.Heat index
Throughout September, the heat index is calculated to be a very hot 100.4°F (38°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.Be aware that heat index ratings are designed for shaded locations and minor breezes. 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 'felt air temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
When the body gets too warm, it perspires, leading to sweat evaporation which cools it down. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When the body's heat gain surpasses its removal capacity, body temperature starts to climb, leading to potential heat-related ailments.
