Weather in September
Temperature
The shift into September records an average high-temperature of a still moderately hot 29.2°C (84.6°F), subtly varied from August's 29.3°C (84.7°F). Throughout September, Saidor registers a consistent average low-temperature of 23.4°C (74.1°F).Heat index
The average heat index in September is evaluated at a fiery hot 35°C (95°F). Greater preventive actions are needed, heat exhaustion and heat cramps are likely. Persistent activity could provoke heatstroke.Heat index determinations are made taking into account the shade and light air movements. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'feels like', provides an understanding of perceived warmth by combining temperature and relative humidity. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular importance for children. Children usually face more risks than adults as their ability to sweat is less. Additionally, their larger skin surface in relation to their petite bodies and higher heat output due to their activities increases their vulnerability.
The physiological way the human body responds to excessive heat is by inducing perspiration, using sweat evaporation as a cooling mechanism. When the level of relative humidity is elevated, evaporation diminishes, causing more warmth to be retained in the body than in dry air. Increasing body temperatures can be a precursor to dehydration if the body can't shed the extra heat.
Humidity
The months with the lowest humidity are July through October, with an average relative humidity of 77%.Rainfall
September is the month with the least rainfall. Rain falls for 22.6 days and accumulates 80mm (3.15") of precipitation.Daylight

Sunshine
The average sunshine in September is 9.1h.UV index
The months with the highest UV index are April through December, with an average maximum UV index of 7. A UV Index value of 6 to 7 symbolizes a high health vulnerability from unsafe exposure to UV radiation for ordinary individuals.Note: A maximum high UV index of 7 in September translates into the following recommendations:
Prevent overexposure. Protection from the sun's harmful effects is needed. Avoid direct exposure to the Sun between 10 a.m. and 4 p.m., the peak period for UV radiation, noting that objects like parasols or canopies might not offer complete sun protection. Experience reduced UV exposure by about half when donning a wide-brim hat.
