Weather in September
Temperature
The average high-temperature during September is a moderately hot 85.6°F (29.8°C), almost matching the conditions of the preceding month. The nighttime temperature dips to an agreeable 68.5°F (20.3°C) on average during September.Heat index
The heat index value during September is evaluated at a fiery hot 96.8°F (36°C). Adopt special protective actions against heat exhaustion and heat cramps. Long-duration activity risks heatstroke.Note that heat index values are valued for light wind and location in the shade. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', gives a temperature feeling by integrating air temperature and humidity. 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. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Children frequently do not comprehend the need for rest and hydration. Thirst is an advanced stage of dehydration - staying hydrated, especially during extended physical exercises, is essential.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Under conditions of increased relative humidity, the evaporation rate lessens, causing the body to retain more heat than under less humid conditions. If heat absorption isn't effectively countered by the body's cooling methods, body temperature surges, hinting at potential problems.
