Weather in June
Temperature
June's arrival coincides with a subtle temperature rise, moving from May's warm 74.3°F (23.5°C) to a still moderately hot 82.2°F (27.9°C). During June, Stephen Knolls observes a consistent average nighttime temperature of 64.4°F (18°C).Heat index
For most parts of June, the heat index is evaluated at a tropical 87.8°F (31°C). Ongoing exposure and activity could lead to a state of exhaustion, with a chance of heat cramps.Know that the heat index computations account for shaded terrains and slight winds. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an estimation of the warmth sensation when considering humidity levels. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
