Weather in September
Temperature
Entering September, Waterford's average high-temperature reads a moderately hot 85.3°F (29.6°C), indicating a close resemblance to the previous month's climate. Waterford in September experiences a low-temperature average of 65.1°F (18.4°C).Heat index
September's average heat index is estimated at a fiery hot 95°F (35°C). Additional precautions are required to avert heat cramps and heat exhaustion. Persistent activity may culminate in heatstroke.Keep in mind the heat index values are meant for areas in shade and with light wind. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', integrates the air's temperature and its humidity to showcase the felt temperature by people. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Keep aware, the sun, when shining directly, can intensify the heat experience, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
When temperatures rise, the human body turns to perspiration, using the cooling power of evaporating sweat. Under high air temperature coupled with high humidity (high heat index), the body's perspiration is reduced, intensifying the sensation of heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.
