Weather in September
Temperature
On the advent of September, Manay's average high-temperature exhibits a minor adjustment to a still moderately hot 29.4°C (84.9°F) from August's 29.5°C (85.1°F). In Manay, the September nights are characterized by an average low-temperature of 25.1°C (77.2°F), a minor dip from daytime readings.Heat index
Throughout September, the heat index is computed to be a very hot 35°C (95°F). Greater safety measures are needed, risk of heat exhaustion and heat cramps is high. Continuous activity might trigger heatstroke.It is crucial to understand that heat index figures are for shade and gentle wind conditions. Heat index values may be hiked up by 15 Fahrenheit (8 Celsius) degrees under direct sunshine.
Note: The heat index, also known as 'real feel' or 'felt air temperature', measures the perceived warmth when incorporating the humidity present in the air. The experience of temperature can be subjective, varying based on the individual's activity and heat perception, influenced by factors like wind, attire, and metabolic variations. When directly under the sun, the weather's impact can intensify, possibly boosting the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are especially crucial for babies and toddlers. Kids are generally in more danger than adults because they perspire less. Their large skin surface area compared to their small bodies and the excessive heat due to their actions raises their risk.
The natural cooling mechanism in humans involves perspiration, where the evaporation of sweat balances out excessive warmth. An increase in relative humidity hinders the body's normal cooling function by reducing evaporation, thereby decreasing the rate of body cooling and enhancing the sense of warmth. When heat surpasses the body's release mechanisms, dehydration and overheating risks become pronounced.
Humidity
August through October, with an average relative humidity of 77%, are the least humid months.Rainfall
The month with the least rainfall is September, when the rain falls for 13.2 days and typically collects 28mm (1.1") of precipitation.Sea temperature

January through December, with an average maximum UV index of 7, are months with the lowest UV index. A UV Index value of 6 to 7 symbolizes a high health hazard from exposure to the Sun's UV radiation for the ordinary person.Note: An average UV index of 7 in September transforms into this advice:
Sidestep overexposure. Individuals with fair complexions risk burning in fewer than 20 minutes. Between 10 a.m. and 4 p.m., the Sun's UV radiation is at its peak. Limit your exposure to direct sunlight during these hours. Outfit yourself in sun-safe attire, like long sleeves, pants, a hat, and UV-blocking sunglasses. Heads up! Sand and water reflection magnifies the UV exposure from the Sun.
