With the onset of September, Keats experiences a modest temperature adjustment, with the average high-temperature gently receding from a hot 87.4°F (30.8°C) in August to a moderately hot 81.5°F (27.5°C). September sees the temperature falling to a mean low of 62.6°F (17°C).Heat index
September's heat index is estimated at a tropical 86°F (30°C). With extended exposure and activity, one might feel exhausted and experience heat cramps.Realize that the values for the heat index are set for shaded places and light winds. The heat index can potentially augment by 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', gives an indication of how one might feel in terms of heat after considering humidity. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. It is essential to be conscious of the fact that direct sunlight can intensify the felt heat, leading to an elevation in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical for children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
