Weather in July
Temperature
July experiences an average high-temperature of a still moderately hot 83.1°F (28.4°C), barely different from June's 78.3°F (25.7°C). In Placentia, the nighttime temperature averages to a comfortable 64.2°F (17.9°C) during July.Heat index
July's mean heat index is estimated at a hot 86°F (30°C). Exposure and extended activity could potentially cause a state of fatigue and lead to heat cramps.Thinking about the heat index, one should account for its values in shaded areas with gentle breezes. Direct sunlight has the potential to heighten heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', combines air temperature and relative humidity to represent a human perceived temperature equivalent. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are highly critical for babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.

Skirt overexposure. People with light complexions might get scorched in under 20 minutes. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a time when UV radiation is at its strongest, and remember that parasols or canopies do not offer full protection. For holistic sun protection encompassing the eyes, ears, face, and neck, a wide-brim hat is key.
