Weather in September

September, the first month of the autumn in Carlson, is still a tropical month, with an average temperature varying between 88.2°F (31.2°C) and 72.7°F (22.6°C).

Temperature

Entering September, the average high-temperature is recorded at a still hot 88.2°F (31.2°C), exhibiting a minimal shift from August's 90.1°F (32.3°C). During September, Carlson observes a consistent average nighttime temperature of 72.7°F (22.6°C).

Heat index

During September, the heat index is calculated to be an extremely hot 105.8°F (41°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.
Heat index details are generally centered around shaded locations and a mild breeze. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', offers an insight into how hot it feels when we factor in moisture content. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. 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 highly critical for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
In high temperatures, perspiration kicks in, allowing the human body to cool down through the evaporation of sweat. When air moisture content is high, the cooling process through evaporation is not as efficient, leading to an ineffective body cooling process and a feeling of overheating. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.

Elude overexposure. Fair-skinned people could get burnt in less than 20 minutes. Stay in the shade and limit direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is particularly strong. Remember, however, that shade structures may not provide complete protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
