Weather in September

September, the first month of the autumn in Dolsen, is still a tropical month, with an average temperature varying between 86.9°F (30.5°C) and 72.5°F (22.5°C).

Dolsen experiences a transition to a still tropical 86.9°F (30.5°C) in average high-temperatures with the arrival of September, not greatly differing from August's 89.6°F (32°C). In Dolsen, an average temperature of 72.5°F (22.5°C) is noted during September nights.

Heat index

September's mean heat index is computed to be a very hot 102.2°F (39°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
Take into consideration that the heat index values are calculated for shade and light wind conditions. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is the outcome of merging air's temperature and its humidity metrics. Factors encompassing physical activity, clothing, and metabolic differences have a role in shaping the individual's impression of temperature. With direct sunlight, be aware that it might enhance the heat sensation, raising the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. 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. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
