Weather in September
Temperature
The onset of September manifests an average high-temperature of a still warm 29.5°C (85.1°F), demonstrating a minor variation from the preceding month. Mandinari's September nights experience a subtle temperature dip to an average of 26.1°C (79°F).Heat index
September's heat index is evaluated at a very hot 36°C (96.8°F). Implement heightened safety measures - risk of heat exhaustion and heat cramps is increased. Prolonged activity may result in heatstroke.In terms of the heat index, values are set with light wind and shade conditions in mind. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', joins air temperature with relative humidity to produce a temperature perception for humans. Factors such as metabolic variation, pregnancy, and physical activity play a role in one's impression of weather. Should you be directly under the sun, anticipate a possible increase in the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are primarily vital for children. Children frequently underestimate the necessity to rest and hydrate. Thirst is a late sign of dehydration - thus, it is vital to stay hydrated, particularly during lengthy physical exercises.
To combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. When relative humidity increases, the body's capacity to evaporate heat decreases, leading to a heightened sense of warmth. Heat disorders may be on the horizon when body temperatures rise from inadequate heat management.
