Weather in September
Temperature
The average high-temperature shows a slight dip in September, from August's hot 93.7°F (34.3°C) to a still tropical 87.8°F (31°C). An average nighttime temperature of 67.1°F (19.5°C) is recorded during September.Heat index
The heat index value during September is computed to be a sweltering 100.4°F (38°C). Incorporate special precautions, risk of heat exhaustion and heat cramps is substantial. Sustained activity could cause heatstroke.Take into consideration that the heat index values are calculated for shade and light wind conditions. Exposure to direct sunlight may make the heat index values climb by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', is the outcome of merging air's temperature and its humidity metrics. This effect is subjective, differing among individuals based on their physical activity and perception of heat, which can be influenced by factors like wind, clothing, and metabolic variances. When in direct sunlight, one should be cautious as it can raise the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are extremely significant for babies and toddlers. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
Humans rely on perspiration as a cooling mechanism, wherein the evaporating sweat counteracts excessive warmth. An upsurge in relative humidity affects normal body cooling mechanisms by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. When the heat gained surpasses the body's cooling capacity, temperatures rise, signaling potential health concerns.
Humidity
July through October, with an average relative humidity of 71%, are the least humid months.Rainfall
The month with the least rainfall is September, when the rain falls for 12.8 days and typically collects 1.77" (45mm) of precipitation.Snowfall

Sunshine
In Haile, the average sunshine in September is 9.7h.UV index
The average daily maximum UV index in September is 6. A UV Index value of 6 to 7 symbolizes a high health hazard from exposure to the Sun's UV rays for the ordinary person.Note: The daily high UV index of 6 in September translates into this advice:
Conform to measures and uphold sun safety traditions. Warding off skin and eye harm is necessary. Seek shade and limit direct sun exposure between 10 a.m. and 4 p.m., the peak period for UV radiation. Keep in mind that shade structures like parasols or canopies do not offer complete sun protection. Limit sun-induced ocular harm with sunglasses that feature UVA and UVB filtration.
