Weather in September
Temperature
The start of September marks an average high-temperature of a still tropical 30.5°C (86.9°F), hardly distinguishable from the conditions in August. Palma de Mallorca's September nights exhibit a subtle drop in temperature, averaging at a warm 25.7°C (78.3°F), closely aligned with the daytime highs.Heat index
September's mean heat index is evaluated at a torrid 39°C (102.2°F). Undertake enhanced precautions, heat exhaustion and heat cramps are possible risks. Continuous activity could trigger heatstroke.Bear in mind that the heat index values are determined for shaded areas and light breezes. The heat index values could be amplified by up to 15 Fahrenheit (8 Celsius) degrees in direct sunlight.
Note: The heat index, also known as 'apparent temperature' or 'real feel', combines both the air temperature and the humidity level to give a perceived human temperature. Factors such as metabolic variations, being pregnant, and physical activity can impact an individual's weather perception. Taking into account that direct sunlight can boost the heat effect, the heat index may rise by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Children often lack awareness of the importance of taking breaks and rehydrating. The feeling of thirst is a late indication of dehydration, so maintaining hydration, especially during long periods of physical activity, is critical.
To offset high temperatures, the human body releases sweat which, upon evaporation, cools it down. 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. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Sunshine

The months with the highest UV index are March through October, with an average maximum UV index of 7. A UV Index of 6 to 7 symbolizes a high health vulnerability from unsafe exposure to UV radiation for ordinary individuals.Note: The maximum daily UV index, 7 in September, converts into the following recommendations:
Inhibit overexposure. Warding off sun damage is of utmost importance. Limit your direct sun exposure, especially between 10 a.m. and 4 p.m., when UV radiation is strongest. Shade structures might not provide complete sun protection. By wearing a generously brimmed hat, you can cut UV radiation exposure significantly.
