Temperature
September indicates a minor shift in the average high-temperature, from August's hot 32.1°C (89.8°F) to a moderately hot 28.3°C (82.9°F). Throughout September, an average low-temperature of 20.5°C (68.9°F) is experienced.Heat index
The heat index value for September is evaluated at a hot 32°C (89.6°F). Unrelenting activity during exposure could cause fatigue and potentially lead to heat cramps.Understanding the heat index involves considering values for shaded locales with light wind. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. 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 noteworthy to mention that direct sunlight exposure can augment the felt temperature, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Kids are usually more vulnerable than adults, given their lesser sweating ability. Along with their larger skin surface relative to their small stature and the excess heat due to their activity, their risk is amplified.
