Weather in June
Temperature
June brings a slight elevation in the average high-temperature, transitioning from May's agreeable 73.2°F (22.9°C) to a moderately hot 81.3°F (27.4°C). From significant daily highs, Markham's nights in June cool down to an average low-temperature of 59.5°F (15.3°C).Heat index
June's mean heat index is calculated to be a tropical 86°F (30°C). Long-standing exposure coupled with ongoing activity could result in exhaustion, possibly causing heat cramps.Take into consideration that the heat index values are calculated for shade and light wind conditions. The heat index has the potential to rise by 15 Fahrenheit (8 Celsius) degrees with direct sunshine exposure.
Note: The heat index, also known as 'real feel' or 'apparent temperature', melds the effects of warmth and moisture to generate a feeling of heat. Factors including metabolic differences, physical activity, and clothing are additional elements that influence the individual's temperature experience. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical 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.
