Weather in July
Temperature
Charlton witnesses the warmest weather in July, with temperatures averaging a high of 81.3°F (27.4°C) and a low of 61.7°F (16.5°C).Heat index
July's average heat index is estimated at a hot 86°F (30°C). If one remains active during constant exposure, it might cause exhaustion and heat cramps.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. Elements such as metabolic variations, pregnancy, and physical exertion can influence 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 highly important for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
