Weather in July
Temperature
July stands out as Jamestown's warmest month, with an average high-temperature of 90.3°F (32.4°C) and a low-temperature of 71.4°F (21.9°C).Heat index
The heat index in July is appraised at an extremely hot 107.6°F (42°C). Adopt enhanced safety measures, heat exhaustion and heat cramps could occur. Continuous activity may induce heatstroke.It is emphasized that the heat index's values are meant for shaded zones with mild winds. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a numerical representation of warmth when taking temperature and moisture levels into account. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. Bear in mind that direct sunshine exposure increases weather impact, and may raise heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Evaporation of sweat is the main factor behind the cooling effect of perspiration in the human body. In high relative humidity, the body's ability to evaporate heat is diminished, resulting in a heightened feeling of warmth. Accumulating heat beyond the body's cooling measures leads to rising temperatures and potential ailments.
