Weather in June
Temperature
Smithfield's weather in June shows a minor rise in the average high-temperature, moving slightly up from May's pleasant 72°F (22.2°C) to a warm 80.8°F (27.1°C). During June nights, Smithfield witnesses a consistent average temperature of 63.7°F (17.6°C).Heat index
The heat index value during June is calculated to be a hot 86°F (30°C). Persisting in activity during long-term exposure might induce weariness, with subsequent heat cramps.Heat index's context suggests values are appropriate for shady areas and slight breezes. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', is an index that combines air temperature and relative humidity to determine the human-perceived temperature equivalent. The individual's impression of temperature can be shaped by additional aspects such as metabolic variations, physical activity, and clothing. Be aware that direct exposure to sunlight increases heat impact and may raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Youngsters generally face more threats than adults given their lesser ability to sweat. Coupled with their larger skin surface relative to their small bodies and higher heat production due to their activities, they are more endangered.
