In Houston, the onset of June comes with an increased average high-temperature, moving from May's warm 79.3°F (26.3°C) to a tropical 89.2°F (31.8°C). In stark contrast to the day's heat, the temperature dips to an average of 67.1°F (19.5°C) during June nights.

Heat index

The heat index for June is estimated at a scorching 105.8°F (41°C). Ensure extra safety steps, heat exhaustion and heat cramps are likely. Long activity might lead to heatstroke.
Know that the heat index computations account for shaded terrains and slight winds. Heat index values may surge by up to 15 Fahrenheit (8 Celsius) degrees in the presence of direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', evaluates the perceived heat by adding the effect of moisture in the air. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Do note, being directly under sun rays can amplify the heat you feel, potentially raising the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Kids generally face higher risks than adults as they sweat less. Along with their large skin surface compared to their small bodies and higher heat production due to their activities, their vulnerability is increased.
In response to overheating, the human body perspires to cool down, mainly through the evaporation of sweat. When the air holds a significant amount of moisture, the efficiency of the evaporation process is decreased, preventing the body from cooling down efficiently, leading to the sensation of overheating. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.
