Weather in July

Humboldt experiences the zenith of summer in July. The sun blazes with its full strength, pushing the temperatures to an average high of 80.8°F (27.1°C). The rising temperature heightens the evaporation rate and causes a notable increase in relative humidity. While the weather might be hot and somewhat muggy, the month sees a decrease in rainfall, relative to the preceding months. The winds also lose some of their vigor, making the heat more apparent.

Temperature

Humboldt's July weather, with an average high temperature of 80.8°F (27.1°C) and an average low temperature of 63.7°F (17.6°C), tends to be the warmest of the year.

Heat index

July's average heat index is estimated at a tropical 86°F (30°C). A sense of exhaustion might occur with extended exposure and activity, potentially causing heat cramps.
Understanding the heat index involves considering values for shaded locales with light wind. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', embodies the combination of air temperature and moisture content to illustrate perceived heat. Elements of metabolic variation, physical activity, and clothing contribute to the effect of temperature on an individual. Consider the sun's direct rays and their impact; they can potentially increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are of high significance for children. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
