Weather in September
Temperature
The onset of September notes an average high-temperature of a still tropical 31.2°C (88.2°F), subtly shifted from August's 30.2°C (86.4°F). In the month of September, the average low-temperature usually rests at an agreeable 22.5°C (72.5°F).Heat index
September's heat index is computed to be a scorching 41°C (105.8°F). Adopt additional preventive measures, heat cramps and heat exhaustion are potential outcomes. Prolonged activity may trigger heatstroke.Observations indicate that the heat index values are for shady locations with light wind. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is a value derived by merging air temperature with the humidity to convey how the climate feels. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. Overheating and dehydration threats arise when heat gain goes beyond what the body can comfortably shed.
