Weather in September
Temperature
Monterey's shift into September sets the average high-temperature at a still hot 87.4°F (30.8°C), a figure that deviates only slightly from August's 91.2°F (32.9°C). An average low-temperature of 68.2°F (20.1°C) marks the month of September in Monterey.Heat index
For most parts of September, the heat index is calculated to be a very hot 102.2°F (39°C). Special measures are necessary to avoid heat cramps and heat exhaustion. Persistent activity could result in heatstroke.When considering the heat index, it's pivotal to note it is for shade and mild wind conditions. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'felt air temperature' or 'real feel', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. One's perception of temperature is subjective, varying based on their activity and individual heat perception, influenced by factors like wind, clothing, and metabolic variations. Be mindful that being in direct sunlight might mean feeling hotter, with the heat index rising by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
The evaporation of sweat is a natural cooling mechanism of the human body, facilitated by perspiration. When relative humidity is on the rise, it curtails evaporation, thereby reducing the heat elimination from the body and causing the feeling of being excessively hot. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
