Weather in July
Temperature
With the beginning of July, Lilac's average high-temperature sees a minor increase, transitioning from 79.5°F (26.4°C) in June to a still warm 85.1°F (29.5°C). Lilac observes a substantial disparity between daytime high and the average low-temperature of 61.3°F (16.3°C) during July nights.Heat index
July's average heat index is calculated to be a hot 89.6°F (32°C). Exposure and extended activity could potentially cause a state of fatigue and lead to heat cramps.Heat index values are typically calculated for conditions of shade and a light breeze. The heat index could experience an increase of 15 Fahrenheit (8 Celsius) degrees due to direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Youngsters are usually more at risk than adults, considering they sweat less. Additionally, their high skin surface area compared to their little bodies and their high heat production due to activity increases their risk.
