Weather in September
Temperature
The average high-temperature in September, at a still tropical 88.2°F (31.2°C), reveals a modest deviation from August's 91.6°F (33.1°C). Jasper's nights in September cool down to an average low-temperature of 70.5°F (21.4°C).Heat index
September's heat index is computed to be an extremely hot 104°F (40°C). Take extra safety measures to prevent heat exhaustion and heat cramps. Heatstroke could follow lengthy activity.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Exposure to direct sunshine can increase heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. The individual's impression of temperature can be affected by numerous factors such as metabolic variations, physical exertion, and attire. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones are generally at greater risk than adults due to their limited sweating ability. In addition, their large skin surface relative to their small bodies and higher heat production from their activities add to their vulnerability.
The body's natural response to excessive warmth is perspiration, as it allows for cooling through sweat evaporation. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. Overheating and potential dehydration arise when body heat gain eclipses its release capability.

Limit exposure to direct sunlight during these hours. For effective sun eye protection, rely on sunglasses certified for UVA and UVB resistance.
