Weather in September
Temperature
The shift from August to September includes a minor decrease in the average high-temperature, lightly dropping from 93.6°F (34.2°C) to a still tropical 88.2°F (31.2°C). Throughout September, the temperature tends to fall to a consistent average low of 69.1°F (20.6°C).Heat index
The heat index in September is estimated at a blisteringly hot 104°F (40°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.Understanding the heat index involves considering values for shaded locales with light wind. Direct sunlight might cause an increase of up to 15 Fahrenheit (8 Celsius) degrees in the heat index.
Note: The heat index, also known as 'feels like' or 'apparent temperature', represents the fusion of temperature and moisture in the air to suggest how warm it feels. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Exposure to direct sun rays can influence the heat you feel, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
Through perspiration, the body has a natural mechanism to eliminate excessive heat via sweat evaporation. An increase in relative humidity retards evaporation, subsequently reducing the body's heat removal rate and leading to a sensation of being overly warm. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

Implement preventive steps and embrace sun safety standards. Protection from skin and eye distress is compulsory. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Protect your eyes, ears, face, and neck from the Sun by wearing a wide-brimmed hat.
