Weather in June
Temperature
As Portland transitions into June, the average high-temperature is observed to rise from 74.8°F (23.8°C) in May to a still warm 85.5°F (29.7°C). Throughout June, an average nighttime temperature of 65.3°F (18.5°C) is experienced in Portland.Heat index
The heat index value for June is calculated to be a torrid 96.8°F (36°C). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.One should be cognizant that the heat index values are tailored for shaded spots 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', provides an understanding of perceived warmth by combining temperature and relative humidity. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely vital to babies and toddlers. Younglings are generally more in peril than adults due to their reduced perspiration. Coupled with a larger skin surface relative to their tiny bodies and greater heat production because of their activity, they become more at risk.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Excessive relative humidity disturbs the body's typical cooling process by reducing evaporation, leading to a decrease in body cooling rate and an increase in the sensation of warmth. Potential thermal conditions emerge as the body's heat gain outpaces its cooling mechanisms.
