Weather in August
Temperature
The onset of August brings an average high-temperature of a still moderately hot 82.8°F (28.2°C), nearly matching the July temperature. Throughout August, Montrose anticipates an average low-temperature of 64°F (17.8°C).Heat index
In August, the heat index is calculated to be a tropical 89.6°F (32°C). Ongoing exposure and activity could lead to a state of exhaustion, with a chance of heat cramps.Heat index data is primarily for areas with shade and subjected to light winds. Direct sunshine exposure could raise heat index values by as much as 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'felt air temperature' or 'apparent temperature', gauges the sensation of temperature factoring in the air's moisture content. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. In direct sunlight, the heat's impact can be heightened, potentially leading to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for children. Children often fail to understand the importance of rest and rehydration. Thirst is a late manifestation of dehydration - hence, it is crucial to stay hydrated, especially during ongoing physical activities.
