Weather in July
Temperature
A minimal variation is noted in Forestville's average high-temperature at the onset of July, reaching a still moderately hot 83.3°F (28.5°C) from June's 79.3°F (26.3°C). Forestville's July nights bring a significant temperature shift, averaging at a fresh 54.1°F (12.3°C).Heat index
Throughout July, the heat index is computed to be a hot 86°F (30°C). Uninterrupted exposure and activity might result in fatigue, potentially causing heat cramps.Metrics for the heat index primarily focus on shaded spots and light wind conditions. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is found by incorporating humidity levels into the air temperature measurement. Elements such as metabolic variations, being pregnant, and physical activity can impact one's weather perception. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.

Deter overexposure. Protecting against the sun's effects is essential. Make an effort to avoid direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation, and note that objects like parasols or canopies might not offer full sun protection. Your best bet for sun defense on the face, eyes, and neck is a hat with a wide brim.
