Weather in September
Temperature
September's onset brings a negligible change in high-temperatures, falling from 92.8°F (33.8°C) in August to a still tropical 86.4°F (30.2°C). Dela observes an average nighttime low-temperature of 65.5°F (18.6°C) during the month of September.Heat index
The heat index in September is computed to be a torrid 95°F (35°C). Take greater precautions, heat exhaustion and heat cramps may be expected. Heatstroke could result from lengthy activity.Given the heat index, its values are aligned with shaded sites and gentle winds. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. Additional factors encompassing metabolic differences, the level of physical activity, and clothing can impact the individual's perception of temperature. When exposed to direct sunlight, it's possible for the heat index to increase by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones often disregard the necessity to rest and hydrate. Thirst usually indicates advanced dehydration - hence, it is key to stay hydrated, particularly during ongoing physical activities.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Heat-related challenges, like dehydration, can be anticipated when body heat isn't managed effectively.
