Weather in September
Temperature
September ushers in a minor alteration in Good Hope's climate, with the average high-temperature moving from August's hot 93°F (33.9°C) to a still tropical 87.6°F (30.9°C). In September, Good Hope experiences a significant drop from daily zeniths to an average nighttime temperature of 66°F (18.9°C).Heat index
For most parts of September, the heat index is appraised at a fiery hot 100.4°F (38°C). Adopt heightened safety measures, heat cramps and heat exhaustion may occur. Sustained activity might cause heatstroke.Take note of the fact that heat index values are based on shaded circumstances with light airflows. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', is derived by integrating air temperature with the existing relative humidity to express the perceived warmth. The impact of weather is individual, with diverse individuals experiencing it differently due to variations in body mass, height, and activity levels. Take note that direct exposure to the sun can increase the felt temperature, possibly adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are primarily vital for children. Children frequently underestimate the importance of resting and drinking fluids. Thirst is a symptom of advanced dehydration - hence the need to hydrate regularly, especially during protracted physical exercises.
Perspiration, which is the evaporation of sweat, is a primary way the human body manages and dispels excessive warmth. A higher relative humidity affects normal body cooling by reducing the evaporation rate, subsequently lowering the rate at which the body cools and increasing the perception of heat. Rising body temperatures resulting from an imbalance in heat absorption can lead to potential thermal issues.
Humidity
July through October, with an average relative humidity of 71%, are the least humid months.Rainfall
September is the month with the least rainfall. Rain falls for 11.5 days and accumulates 2.01" (51mm) of precipitation.Snowfall

Sunshine
The average sunshine in September is 9.6h.UV index
The average daily maximum UV index in September is 6. A UV Index estimate of 6 to 7 represents a high health hazard from exposure to the Sun's UV rays for the ordinary person.Note: The maximum UV index of 6 during September leads to these instructions:
Avoid overexposure. Fair-skinned individuals can burn in under 20 minutes. The Sun's UV radiation is most potent between 10 a.m. and 4 p.m. Try to limit direct exposure to the Sun during this period. Sun-protective clothing, a long-sleeved shirt and pants, a wide-brimmed hat, and UVA and UVB-blocking sunglasses are particularly helpful in blocking UV radiation's harmful effects.
