Weather in September
Temperature
Khartail marks the onset of September with an average high-temperature of a still hot 32.4°C (90.3°F), a subtle shift from August's 32.6°C (90.7°F). The average low-temperature, in September, is a warm 25.7°C (78.3°F).Heat index
The average heat index in September is computed to be a life-threatening hot 46°C (114.8°F). Mindful: Heat cramps and heat exhaustion are to be expected. Extended physical effort might result in heatstroke.Records show heat index calculations are tailored for shaded regions and mild winds. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gauges the sensation of temperature factoring in the air's moisture content. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Young ones often ignore the need to take a break and drink fluids. Thirst is a late-stage symptom of dehydration - hence, maintaining hydration, particularly during extended physical activities, is crucial.
The human body cools itself through perspiration, as excessive warmth is removed from the body through sweat evaporation. High relative humidity reduces the evaporation rate, resulting in a lower heat removal rate from the body, causing the perception of being overheated. As body temperatures escalate without effective heat release, one might face dehydration threats.

March through September, with an average maximum UV index of 7, are months with the highest UV index. A UV Index estimate of 6 to 7 represents a high health vulnerability from exposure to the Sun's UV rays for average individuals.Note: A typical high UV index of 7 in September suggests the following recommendations:
Refrain from overexposure. Fair-skinned individuals could burn in under 20 minutes. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. Sunglasses that ward off UVA and UVB rays play a pivotal role in reducing solar eye damage.
