Weather in September
September in Escuintla presents a continuation of the wet season characterized by persistent rainfall and high humidity levels. However, the conditions witness a subtraction in terms of temperatures, from those of August. The decrease in sunshine hours under the cloudy skies has a slight impact on outdoor activities. Still, the drop in temperature ensures some form of comfort despite the high precipitation levels. While the wind speeds drop slightly, they still remain visibly stronger as compared to the beginning of the year.Temperature

Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is a measure of how hot it feels when the actual air humidity is factored in. The impact of temperature is individual, as people's perception of weather may change based on their body mass, height, and physical activity. 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 extremely significant for children. Children often do not understand the need to rest and hydrate. Thirst is a late manifestation of dehydration - therefore, it is essential to stay hydrated, particularly during prolonged physical activities.
