Weather in June
Temperature
With the onset of June, Upland's average high-temperature experiences a slight rise, moving from May's 76.6°F (24.8°C) to a still moderately hot 84°F (28.9°C). Despite high daytime temperatures, the average temperature in Upland lowers to a mild 58.5°F (14.7°C) during June nights.Heat index
During June, the heat index is computed to be a tropical 86°F (30°C). Ongoing exposure and activity could lead to a state of exhaustion, with a chance of heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is the result of factoring in humidity to the air temperature, indicating perceived warmth. The effect is personal, with varied weather perceptions among individuals due to differences in body mass, stature, and physical activity. Considering the impact of direct sunlight, it's possible for the heat index to surge by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young individuals are generally in more danger than adults due to their lower capacity to sweat. Moreover, their large skin surface in relation to their small bodies and the increased heat generation from their activities makes them more vulnerable.
