Weather in September
Temperature
September's advent denotes a minor fluctuation in the average high-temperature to a warm 84.9°F (29.4°C) from August's 90°F (32.2°C). The nighttime temperature in Monmouth dips to an enjoyable 65.3°F (18.5°C) on average during September.Heat index
The heat index in September is evaluated at a tropical 93.2°F (34°C). Exercise increased caution, heat cramps and heat exhaustion are potential hazards. Continuous activity could lead to heatstroke.In reference to the heat index, it's for places in shade and with a slight wind. Heat index values have the potential to be boosted by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'real feel' or 'feels like', ties air temperature with relative humidity to produce the perceived temperature sensation. The influence of weather is personal, differing among a variety of individuals based on differences in body mass, stature, and the level of physical activity. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly meaningful for babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
