Weather in June
Temperature
With the onset of June, Oakville's weather sees a temperature rise, transitioning from a moderately hot 73.6°F (23.1°C) in May to a still warm 82.8°F (28.2°C). A striking departure from daytime highs to an average low-temperature of 53.2°F (11.8°C) is witnessed during June.Heat index
For most parts of June, the heat index is calculated to be 84.2°F (29°C). Uninterrupted activity during exposure could lead to a sense of exhaustion, possibly causing heat cramps.Given the heat index, its values are aligned with shaded sites and gentle winds. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. Depending on the activity and the individual's heat perception, which may vary due to factors including wind, clothing, and metabolic variations, this effect remains subjective. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. In general, younger individuals are at greater risk than adults because they tend to sweat less. Also, having a larger skin surface to body size ratio and greater heat production due to their active behavior contribute to this danger.
