Weather in July
Temperature
In Oakley, the peak temperatures are generally noted in July, averaging a high of 88.5°F (31.4°C) and a low of 56.5°F (13.6°C).Heat index
July's average heat index is estimated at a hot 93.2°F (34°C). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.For clarity, heat index numbers account for light winds and areas under shade. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', stands as a testimony to how temperature and humidity combine to impact our sense of warmth. Physical activity, clothing, and metabolic variations are additional factors that impact an individual's perception of temperature. Under direct sun rays, the felt temperature might be heightened, with the heat index increasing by 15 Fahrenheit (8 Celsius) degrees. Heat index values remain especially vital for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
