Weather in September
Temperature
The introduction of September sees an average high-temperature of a warm 85.3°F (29.6°C), hardly deviating from August. During September nights, Rupert witnesses a consistent average temperature of 67.5°F (19.7°C).Heat index
September's mean heat index is appraised at a torrid 95°F (35°C). Preventive measures are required to mitigate the risk of heat cramps and heat exhaustion. Continuous activity may precipitate heatstroke.Observations indicate that the heat index values are for shady locations with light wind. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', comes about by integrating the temperature readings with the humidity levels. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Direct sun exposure is noteworthy in its ability to escalate the felt temperature, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are quite important for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. When the relative humidity is high, the evaporation rate is reduced. The warmth is removed from the body at a lower rate, causing the body to retain more heat than it would in dry air. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.

Beware of overexposure. Fair-skinned individuals risk burning in less than 20 minutes. UV radiation from the sun is at its strongest between 10 a.m. and 4 p.m. Try to limit direct exposure during these hours. Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears.
