Weather in September
Temperature
Transitioning into September, Olingan records an average high-temperature of a warm 29.8°C (85.6°F), almost identical to August's 30.3°C (86.5°F). September nights are marked by an average low-temperature of 24.5°C (76.1°F).Heat index
In September, the heat index is calculated to be a very hot 37°C (98.6°F). Exercise heightened safety, heat cramps and heat exhaustion are probable. Persistent activity may provoke heatstroke.Be aware that heat index ratings are designed for shaded locations and minor breezes. The direct sunshine could escalate the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'real feel', joins air temperature with relative humidity to produce a temperature perception for humans. One's perception of weather can be shaped by other factors, involving metabolic differences, pregnancy, and physical exertion. It is essential to realize that direct sunlight can escalate the perceived temperature, increasing the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly important for children. In general, children are more at risk than adults because they sweat less. Furthermore, the large skin surface compared to their small bodies and the high heat production due to their actions contribute to this vulnerability.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. When relative humidity is heightened, it slows the rate of evaporation, thereby decreasing the body's ability to shed heat and creating a sensation of overheating. Exceeding the body's heat disposal threshold results in a rise in body temperature and potential thermal disorders.
Humidity
The average relative humidity in September is 79%.Rainfall
In September, the rain falls for 24.6 days. Throughout September, 82mm (3.23") of precipitation is accumulated. Throughout the year, there are 265.5 rainfall days, and 947mm (37.28") of precipitation is accumulated.Sea temperature
In September, the average sea temperature is 29.3°C (84.7°F).Note: Water temperatures between 25°C (77°F) and 29°C (84.2°F) are regarded as highly pleasant, making all water activities enjoyable without any discomfort over long durations.

The average length of the day in September is 12h and 10min.On the first day of the month, sunrise is at 5:38 am and sunset at 5:54 pm. On the last day of September, sunrise is at 5:34 am and sunset at 5:38 pm PST.
Sunshine
In September, the average sunshine is 8.3h.UV index
The months with the highest UV index are January through December, with an average maximum UV index of 7. The months with the lowest UV index are January through December, with an average maximum UV index of 7. A UV Index of 6 to 7 symbolizes a high threat to health from unprotected exposure to Sun's UV rays for ordinary individuals.Note: In September, the maximum UV index of 7 transforms into these recommendations:
Shield from overexposure. Defense against sun-related harm is required. Avoid direct Sun exposure and stay in the shade between 10 a.m. and 4 p.m., a time when UV radiation is most intense, noting that not all shade structures offer full protection. A hat with a generous brim can prevent nearly 50% of UV rays from reaching your eyes. Caution! The reflection of sand and water significantly amplifies the Sun's UV radiation.
