Weather in July
Temperature
July's arrival signals a subtle increase in average high-temperatures, moving from June's agreeable 72.1°F (22.3°C) to a moderately hot 80.8°F (27.1°C). Happy Valley reports a steady low-temperature average of 52.3°F (11.3°C) throughout July, revealing a large deviation from the daytime high.Heat index
July's heat index is calculated to be 84.2°F (29°C). If one remains active during constant exposure, it might cause exhaustion and heat cramps.It is crucial to understand that heat index figures are for shade and gentle wind conditions. In the presence of direct sunshine, the heat index could be augmented by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. 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.
