Weather in September
Temperature
The average high-temperature in September, at a still moderately hot 27.8°C (82°F), reveals a modest deviation from August's 27.5°C (81.5°F). Arabuko notes an average temperature descent to a still warm 23.8°C (74.8°F) in September, a small shift from its daytime peak.Heat index
September's mean heat index is evaluated at a tropical 31°C (87.8°F). With prolonged exposure and constant activity, one might feel exhausted and experience heat cramps.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Direct sun rays can make one feel hotter, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are largely significant for babies and toddlers. 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.
