Weather in September
Temperature
Douva records an average high-temperature of a tropical 30.2°C (86.4°F) in September, closely mirroring the climate of the previous month. An average temperature of 21.5°C (70.7°F) is recorded during the nights in September.Heat index
For most parts of September, the heat index is estimated at a very hot 37°C (98.6°F). Take special precautions - heat exhaustion and heat cramps are expected. Heatstroke may occur with lengthy activity.Evaluating the heat index requires understanding its values in the shade and with gentle winds. A direct sunlight exposure may boost the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', ties air temperature with relative humidity to produce the perceived temperature sensation. A person's impression of weather can be shaped by several aspects, among them metabolic variations, pregnancy, and levels of physical activity. Remember, direct sunlight exposure can heighten the heat impact and might increase the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to children. Typically, young kids are at a higher risk than adults since they sweat less. Also, the larger skin surface in proportion to their small bodies and the heightened heat production due to their active nature adds to their vulnerability.
As a reaction to high temperatures, the human body begins to perspire, using the evaporation of sweat to lower its temperature. In conditions of both high temperature and humidity (a high heat index), sweating is limited and the perception of heat is enhanced. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.

Sunshine
In Douva, the average sunshine in September is 10.7h.UV index
In September, the average daily maximum UV index is 7. A UV Index reading of 6 to 7 represents a high health vulnerability from unsafe exposure to UV radiation for the average person.Note: The daily high UV index of 7 during September translates into the following recommendations:
Take precautions and adopt sun safety practices. Protection against sunburn is obliged. Between 10 a.m. and 4 p.m., the Sun emits the most powerful UV radiation. Limit direct exposure to the Sun during these hours. Always opt for UVA and UVB-resistant sunglasses on radiant days.
