Weather in September
Temperature
September brings an average high-temperature of a still warm 28.9°C (84°F), showing a slight difference from August's 28.8°C (83.8°F). Throughout September, an average low-temperature of 21.1°C (70°F) is expected.Heat index
For most parts of September, the heat index is appraised at a torrid 37°C (98.6°F). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. 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 'apparent temperature', combines both the air temperature and the humidity level to give a perceived human temperature. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital 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.
One way the human body deals with excessive warmth is by perspiring and allowing sweat to evaporate. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.

Adopt protective measures - Requirement to safeguard skin and eyes from harm exists. Midday Sun has the strongest UV rays, making it crucial to limit exposure and find shade. To cut down UV radiation exposure by about half, sport a wide-brim hat.
