Weather in June
Temperature
The start of June brings a subtle rise in the average high-temperature, moving from 76.6°F (24.8°C) in May to a still moderately hot 84.7°F (29.3°C). Alta Loma's average low-temperature of 58.3°F (14.6°C) in June reflects a considerable decline from the daytime peak.Heat index
The heat index value for June is computed to be a hot 86°F (30°C). Ongoing exposure and activity could lead to a state of exhaustion, with a chance of heat cramps.Note that heat index values are valued for light wind and location in the shade. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. One's weather perception can be influenced by a range of factors including metabolic differences, being pregnant, and their level of physical activity. Sunshine, when direct, has the potential to intensify weather effects, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial 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.
