Weather in July
Temperature
In Yreka, the warmest months are July and August, registering an average high-temperature of 84.2°F (29°C).Heat index
In July, the heat index is estimated at a hot 86°F (30°C). If one stays active during extended exposure, it might induce fatigue and result in heat cramps.For clarity, heat index numbers account for light winds and areas under shade. Exposing to direct sunshine may enhance heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. Realize that direct exposure to sunlight can augment the felt heat, leading to a potential increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly important for children. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.

Eschew overexposure. Those with light skin may suffer burns in fewer than 20 minutes. Stay in the shade and limit sun exposure from 10 a.m. to 4 p.m., when UV radiation is most potent. Keep in mind that shade structures like parasols or canopies do not offer full protection. In bright sunlight, prioritize sunglasses that grant protection from UVA and UVB radiation.
