Weather in July
Temperature
July stands out as Ukiah's warmest month, with an average high-temperature of 85.3°F (29.6°C) and a low-temperature of 53.6°F (12°C).Heat index
The heat index value for July is computed to be a hot 89.6°F (32°C). Exhaustion becomes probable with enduring exposure and activity, potentially causing heat cramps.Heat index readings emphasize conditions of light breezes and shaded spots. Under direct sunshine, the heat index values might be elevated by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', determines the feeling of heat when you account for the relative humidity. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Young individuals usually face greater risks than adults as their sweat production is less. Also, their larger skin surface relative to their small bodies and the high heat generation due to their activity contributes to their vulnerability.
