Weather in June
Temperature
June in Pomona brings a slight increase in the average high-temperature, progressing from 76.3°F (24.6°C) in May to a still moderately hot 82.9°F (28.3°C). June nights showcase a dramatic shift from daytime highs to an average temperature of 58.5°F (14.7°C).Heat index
For most parts of June, the heat index is evaluated at 84.2°F (29°C). Prolonged activity during exposure might result in a state of fatigue and cause heat cramps.Heat index determinations are made taking into account the shade and light air movements. Direct sunlight can potentially boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'feels like', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Always consider that direct sunlight exposure might heighten the heat's effects, pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially vital to children. 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.
