Weather in June
Temperature
The onset of June introduces a subtle rise in the average high-temperature, nudging from a warm 73.9°F (23.3°C) in May to a still moderately hot 81.9°F (27.7°C). Throughout the month of June, Mount Rainier witnesses an average temperature of 64.6°F (18.1°C).Heat index
For June, the heat index is estimated at a tropical 87.8°F (31°C). If one sustains activity during exposure, it could lead to a sense of fatigue, with a chance of heat cramps.Evaluating the heat index requires understanding its values in the shade and with gentle winds. If exposed to direct sunlight, the heat index could climb by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial 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.
