A subtle rise in the average high-temperature is observed during June, adjusting from an agreeable 73°F (22.8°C) in May to a moderately hot 81°F (27.2°C). Dennison records an average nighttime low of 63.9°F (17.7°C) in June.Heat index
For June, the heat index is computed to be a tropical 86°F (30°C). Enduring exposure and unrelenting activity might cause a state of weariness, potentially leading to heat cramps.One should consider that heat index numbers are for shaded settings and light wind. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a composite of temperature and humidity figures to convey how warm it feels. 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. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. Young children typically face greater hazards than adults because they do not sweat as much. Their larger skin surface in comparison to their little bodies and the high heat production from their active nature compounds their vulnerability.
