Weather in September

September, the first month of the autumn in Baticane, is still a hot month, with an average temperature ranging between max 32.7°C (90.9°F) and min 22.5°C (72.5°F).

Temperature

At the onset of September, Baticane records an average high-temperature of a still tropical 32.7°C (90.9°F), showing little deviation from the preceding month. Throughout September, the temperature tends to fall to a consistent average low of 22.5°C (72.5°F).

Heat index

During September, the heat index is evaluated at a burning hot 47°C (116.6°F). Careful: Heat exhaustion and heat cramps are anticipated. With ongoing exertion, heatstroke becomes a possibility.
Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', arises from combining readings of air temperature and relative moisture content. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. It is important to note that direct sunlight can intensify the weather impact, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Rising body temperatures due to excess heat retention could signify impending heat disorders.

As much as possible, limit direct sun exposure during this period. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
