For most parts of September, the heat index is evaluated at a very hot 95°F (35°C). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. If directly exposed to the sun, the heat index could rise by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is a metric representing the sensation of warmth when air temperature and moisture come together. Elements such as metabolic variations, pregnancy, and physical exertion can shape one's weather perception. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young ones often underestimate the need for rest and rehydration. Thirst appears late in dehydration - hence, it is important to keep hydrated, particularly during prolonged physical activities.
Sweat evaporation plays a crucial role in cooling the human body, a process enabled by perspiration. Under high air temperature and humidity (high heat index) conditions, perspiration is limited, and the perception of heat is increased. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.

A hat with a broad brim is indispensable, filtering out up to half of UV rays.
