Weather in September
Temperature
The shift into September reveals an average high-temperature of a still tropical 31.9°C (89.4°F), closely mirroring August's climate. Polasara, in September, experiences an average temperature of 26°C (78.8°F) at night.Heat index
The heat index in September is estimated at a blistering 43°C (109.4°F). Mindful: Heat cramps and heat exhaustion are to be expected. Extended physical effort might result in heatstroke.Heat index guidelines indicate values are for light wind scenarios and shaded regions. The heat index has the possibility to be enhanced by 15 Fahrenheit (8 Celsius) degrees when there is direct sun exposure.
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 perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. In situations of high air temperature combined with high humidity (significant heat index), the body's ability to perspire is reduced, heightening the sense of warmth. The body faces dehydration threats when its cooling efforts are outpaced by excessive heat gain.

Apply measures and align with sun safety principles. Safeguarding against skin and eye injury is pivotal. From 10 a.m. to 4 p.m., when UV radiation is at its strongest, limit direct exposure to the Sun and note that shade structures may not provide full sun protection. Wearing a wide-brim hat can block approximately 50% of UV radiation, protecting the eyes.
