Weather in June
Temperature
June's onset witnesses a minor shift in the average high-temperature, moving from a moderately hot 81.5°F (27.5°C) in May to a hot 89.1°F (31.7°C). In June, Portland encounters an average low-temperature of 72.1°F (22.3°C) during the night.Heat index
The heat index value during June is computed to be a scorching 104°F (40°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.Understand that the heat index values take into account shaded locations and mild winds. Exposure to the direct sun might augment heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', is a single figure representing how weather conditions feel when combining temperature and humidity. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Kids frequently fail to realize the necessity for resting and hydrating. Thirst is an advanced indication of dehydration - hence, maintaining hydration, especially during extended physical activities, becomes essential.
The human body normally cools itself by perspiration. Excessive warmth is eliminated from the body by evaporation of sweat. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Heat-related disorders may develop if heat gain in the body overshadows its cooling capacity, leading to elevated temperatures.
