The climatic shift witnessed in September guides Dânan into the subsequent transition phase, preparing it for the latter months.

Temperature

September's onset records an average high-temperature of a still sweltering 35.6°C (96.1°F), a near match to August's 36.9°C (98.4°F). An average low-temperature of 30°C (86°F) is noted during the nights in September.

Heat index

In September, the average heat index is evaluated at a blistering 44°C (111.2°F). Keep wary: Heat cramps along with heat exhaustion are expected. Heatstroke is a possible outcome of ongoing activity.
Know that the heat index computations account for shaded terrains and slight winds. Direct exposure to sunlight could raise the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'apparent temperature', reflects the blend of air temperature and relative humidity to give a temperature impression. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. Keep in mind that direct sunshine exposure can amplify the weather's effects, possibly increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are essentially critical 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.
Evaporating sweat, thanks to perspiration, acts as a natural air conditioner for the human body. With a high level of moisture in the air, the evaporation process becomes less efficient, preventing the body from cooling down efficiently and resulting in a sensation of overheating. Should the body fail to balance its heat gain, the escalating temperature poses health challenges.

Note: The maximum UV index of 8 during September leads to these instructions:
Ensure precautions are always in place. The risk to skin and eyes is high without them. Attempt to stay under shade and limit exposure to the Sun between 10 a.m. and 4 p.m., when UV radiation is at its peak. Remember, devices such as parasols or canopies might not provide complete sun protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes. Be informed! The Sun's UV radiation can be nearly doubled due to the reflection from snow.
