Weather in September
Temperature
Newton starts September with an average high-temperature of a still hot 86.7°F (30.4°C), hinting at a minimal fluctuation from August. Newton's nighttime temperature in September drops to an average of 66.9°F (19.4°C).Heat index
September's average heat index is evaluated at a very hot 98.6°F (37°C). Implement additional safety measures to avoid heat cramps and heat exhaustion. Persistent activity might trigger heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. 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 largely significant for babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.
