The heat index value for September is estimated at a fiery hot 100.4°F (38°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is calculated by taking the relative humidity value for a specific location and factoring it into the air temperature reading. The impact of weather on an individual can be subjective, affected by the person's activity and heat perception, which can vary due to elements including wind, clothing, and metabolic differences. With the sun shining directly, it's crucial to understand that it can increase the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
When faced with excessive heat, the human body begins to perspire, utilizing the cooling benefits of sweat evaporation. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
