Weather in September
Temperature
As August transitions into September, Guiljungan records an average high-temperature of a still warm 28.4°C (83.1°F), showing a gentle shift from the preceding month. The nighttime temperature in September experiences a minor dip, averaging a still warm 23.8°C (74.8°F).Heat index
September's average heat index is estimated at a hot 34°C (93.2°F). More protective measures are required - heat exhaustion and heat cramps are likely. Heatstroke may follow lengthy activity.It is essential to grasp that the heat index's numbers are for shade and light wind settings. A rise in the heat index by 15 Fahrenheit (8 Celsius) degrees may result from direct sunlight exposure.
Note: The heat index, also known as 'real feel' or 'felt air temperature', embodies the combination of air temperature and moisture content to illustrate perceived heat. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. Direct sun rays have a notable impact on perceived temperature, which can raise the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Kids are usually in more danger than grown-ups as they tend to sweat less. Plus, their bigger skin surface in relation to their small frames and increased heat generation due to their activity level make them more susceptible.
