Weather in September
Temperature
September's advent notes a subtle adjustment in average high-temperature to a still tropical 88.7°F (31.5°C) from August. Georgetown experiences a steady low-temperature of 73.4°F (23°C) throughout September.Heat index
For most parts of September, the heat index is computed to be an extremely hot 107.6°F (42°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'felt air temperature' or 'real feel', embodies the combination of air temperature and moisture content to illustrate perceived heat. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold great significance to children. Children commonly overlook the importance of rest and fluid replenishment. Thirst, being a delayed sign of dehydration, emphasizes the need to keep hydration up, especially during lengthy physical activities.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. As body temperatures escalate without effective heat release, one might face dehydration threats.
