Weather in June
Temperature
The beginning of June marks a minor shift in the average high-temperature, moving from May's moderately hot 75.6°F (24.2°C) to a still warm 84.4°F (29.1°C). Nighttime temperatures throughout June register a significant deviation from the day's highs, averaging at a fresh 55°F (12.8°C).Heat index
The heat index value for June is evaluated at a tropical 86°F (30°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. The heat index could see an increase by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'feels like' or 'real feel', represents the fusion of temperature and moisture in the air to suggest 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. Direct exposure to the sun's rays can enhance the felt temperature, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. Children typically face more danger than adults as their sweat production is usually lower. Additionally, the bigger skin surface compared to their small size and the increased heat due to their activeness exacerbate the risk.
