Weather in June
Temperature
As Helena welcomes June, the average high-temperature sees a rise, transitioning from a warm 78.6°F (25.9°C) in May to a tropical 91.6°F (33.1°C). Helena records an average nighttime low-temperature of 71.4°F (21.9°C) throughout June.Heat index
The heat index for June is appraised at a very hot 102.2°F (39°C). Ensure additional precautions, heat exhaustion and heat cramps may be expected. Heatstroke could occur from sustained activity.From a standpoint of the heat index, values pertain to shaded conditions and mild breezes. Heat index values may rise by up to 15 Fahrenheit (8 Celsius) degrees when exposed to direct sunlight.
Note: The heat index, also known as 'feels like' or 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. The individual's temperature perception can be influenced by numerous factors such as metabolic variations, physical activity, and clothing. Given the impact of direct sunlight, it's noteworthy that the felt temperature can rise by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Youngsters typically face more danger than adults since they sweat less. Their larger skin surface compared to their small bodies and heightened heat production from their activities augment their vulnerability.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. In circumstances of high air temperature and humidity (high heat index), the body's perspiration is restricted, heightening the feeling of warmth. Inadequate heat shedding in the face of rising body temperatures hints at potential dehydration risks.
