Weather in June
Temperature
Coffeen's transition into June is marked by a minor temperature shift, moving from a warm 73.6°F (23.1°C) in May to a still moderately hot 81.9°F (27.7°C). Throughout June, the temperature falls to an average low of 65.5°F (18.6°C).Heat index
June's average heat index is computed to be a hot 87.8°F (31°C). With constant exposure and activity, a state of weariness might ensue, leading to potential heat cramps.In reference to the heat index, it's for places in shade and with a slight wind. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is what the temperature feels like to the human body when the air temperature is combined with the relative humidity. The impression of weather on a person can be swayed by additional aspects, including metabolic variations, pregnancy, and activity levels. 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 highly critical to babies and toddlers. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
