Heat index

For most parts of September, the heat index is computed to be a burning hot 49°C (120.2°F). Careful: Heat exhaustion and heat cramps are anticipated. With ongoing exertion, heatstroke becomes a possibility.
Understand that the heat index values take into account shaded locations and mild winds. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Typically, children face more danger than adults as they usually perspire less. Their larger skin surface relative to their small bodies and increased heat output from their activities enhance their risk.
The body's innate mechanism to counteract overheating is through perspiration, as it leverages the cooling effects of sweat evaporation. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Temperature imbalances caused by excessive heat retention can trigger heat-related maladies.

Humidity

The average relative humidity in September is 74%.

Prioritize a wide-brim hat for comprehensive sun defense for your face, neck, eyes, and ears.
