October represents a noticeable change in Barisal's climate, with the city moving away from the Monsoon season. The city experiences a significant decrease in rainfall, marking the start of the dry season again. Comparatively, it is one of the cooler months after the scorching summer and wet monsoon months. The relative humidity also lowers in October, providing more ease for outdoor activities. Consequently, temperatures start dipping to an average of 24°C (75.2°F) even as the sunlight duration remains stable.

Temperature

The onset of October marks an average high-temperature of a still hot 30.5°C (86.9°F), hardly differing from September's 31.7°C (89.1°F). Barisal records a steady low-temperature average of 24°C (75.2°F) during October.

Heat index

The heat index for October is computed to be a very hot 39°C (102.2°F). Extra precautions are necessary, heat cramps and heat exhaustion are plausible outcomes. Extended activity could lead to heatstroke.
In reference to the heat index, it's for places in shade and with a slight wind. Exposure to the direct sun could elevate the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'apparent temperature' or 'felt air temperature', is an indicator that blends the effects of temperature and humidity to depict perceived warmth. An individual's perception of weather can be influenced by a variety of factors including metabolic differences, being pregnant, and their degree of physical exertion. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values hold particular significance for children. Children regularly disregard the necessity to rest and replenish fluids. Thirst is a late symptom of dehydration - thus, maintaining hydration, particularly during long-lasting physical activities, is essential.
To prevent overheating and help regulate its internal temperature, the human body sweat and rely on the evaporation to cool down. With high air temperature and humidity (high heat index) conditions, sweat production is restricted, leading to an amplified perception of heat. With body temperatures on the rise, inefficient heat shedding can lead to dehydration and its associated complications.

Avert overexposure. Light-skinned people might experience burning in less than 20 minutes. Stay in the shade and limit direct sun exposure between 10 a.m. and 4 p.m., when UV radiation is at its strongest. Remember, however, that not all shade structures provide full sun protection. Sunglasses that guard against UVA and UVB rays are pivotal in minimizing sun-induced ocular damage.
