Weather in September
Temperature
The arrival of September is marked by an average high-temperature of a still tropical 30.5°C (86.9°F), bearing a close resemblance to August. An average low-temperature of 26.5°C (79.7°F) is witnessed throughout the month of September in Popolnáh, Mexico, a mere drop from the daytime peak.Heat index
In September, the average heat index is calculated to be a very hot 39°C (102.2°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.It is important to note that the heat index values are for shaded areas and light wind scenarios. Facing direct sunlight may hike up the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', gauges the sensation of temperature factoring in the air's moisture content. One's perception of temperature can vary depending on physical activity and individual heat sensitivity, influenced by factors like wind, attire, and metabolic variations. Consider that direct sun exposure can intensify the felt heat, adding potentially 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are essentially critical for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. During high air temperature and humidity (high heat index), the process of perspiration is hindered, intensifying the sensation of heat. When body heat isn't effectively managed, risks of dehydration and overheating amplify.
