Weather in July
Temperature
Helena's July weather reaches an average high of 90.5°F (32.5°C) and an average low of 71.2°F (21.8°C), making it the warmest month.Heat index
For July, the heat index is appraised at a blistering 111.2°F (44°C). Forewarned: Heat cramps and heat exhaustion are anticipated. Ongoing physical activity increases the likelihood of heatstroke.In the scope of the heat index, its values resonate with shade and light wind conditions. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', shows a temperature sensation when both heat and moisture conditions are combined. The perception of temperature can be subjective, varying based on activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Understand that direct sun rays can influence the weather's impact, leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
To achieve cooling, the human body employs perspiration, relying on the subsequent evaporation of sweat. Under conditions of high relative humidity, the rate of evaporation decreases. This results in the body retaining more heat than under conditions of dry air. When heat uptake goes beyond the body's cooling mechanisms, there's a surge in body temperature, posing health risks.
