October weather forecastCornillon, Haiti

Weather in October

October in Cornillon continues the cooling trend, with a balance of wet and warm conditions. A significant dip in rainfall levels compared to September and a continuous decrease in temperatures add to the versatility of October weather. It is a time where subtler changes in humidity, wind speed, and cloud cover paint a varied weather scenario each day. The lengthening night hours invite to nighttime city exploration. Heading into November, further temperature drops and reduced rainfall mark the onset of the end of the year.

Temperature

October's climate shows a minor adjustment in average high-temperatures to a still warm 29.2°C (84.6°F) from September's 29.8°C (85.6°F). Cornillon throughout October, records an average low-temperature of 20.8°C (69.4°F).

Heat index

The heat index in October is calculated to be a very hot 35°C (95°F). Heightened safety actions are necessary, heat cramps and heat exhaustion are probable. Persistent activity may lead to heatstroke.
When assessing, remember that heat index measurements are for light winds and shaded spots. Direct exposure to sunshine could lead to a heat index increase by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'feels like' or 'felt air temperature', ties air temperature with relative humidity to produce the perceived temperature sensation. This effect tends to be personal, with the weather perception differing among individuals due to variations in body mass, height, and exertion. One should be aware that direct sunshine can amplify the perceived temperature, raising the heat index by as much as 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly relevant to babies and toddlers. Young individuals are typically more threatened than adults due to their reduced perspiration. Also, the larger skin surface proportionate to their small bodies and the increased heat from their activities magnify their risk.
The physiological response of the human body to excess warmth is to perspire, thereby cooling itself through sweat evaporation. With a lot of moisture in the air, the evaporation process is not as effective, and the body does not cool down as efficiently, creating a perception of overheating. Excessive heat that's not properly managed leads to increased body temperatures and resultant health issues.

Humidity

The average relative humidity in October is 79%.

UV index

Note: The UV index of 6 in October translates into these instructions:
Take precautions against overexposure. Protection against sun damage is needed. UV radiation from the Sun is most intense between 10 a.m. and 4 p.m. Try to avoid direct sunlight during this period. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized.
