Weather in September
Temperature
Kestalan notes an average high-temperature of a tropical 30.3°C (86.5°F) in September, hardly diverging from August. The temperature dips to an average of 20.9°C (69.6°F) during September nights.Heat index
Throughout September, the heat index is evaluated at a very hot 37°C (98.6°F). Adopt heightened preventive measures, heat exhaustion and heat cramps are probable. Persistent activity could lead to heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. Overheating and potential dehydration arise when body heat gain eclipses its release capability.
