May weather forecast
Barisal, Bangladesh

May can be pinpointed as the start of the wet season in Barisal, with distinct spikes in rainfall, humidity, and cloud coverage. The temperature drops slightly from the peak of April, indicating a transition towards the rainy season. This month brings the highest relative humidity of the year, reaching up to 70%, leading to a significant increase in cloud coverage. Nonetheless, the sunlight duration remains high, revealing a stark contrast of occurrences in the atmospheric conditions. As this period progresses, wind speed increases providing some respite from the otherwise sultry weather.

Temperature

May observes an average high-temperature of a still fiery hot 35°C (95°F), marking an insignificant difference from April's 35.3°C (95.5°F). During the month of May, the temperature falls to an average of 27.7°C (81.9°F).

Heat index

The heat index value during May is calculated to be a burning hot 50°C (122°F). Stay on guard: Heat exhaustion and heat cramps are predicted. Ongoing effort can cause heatstroke.
Be informed that the heat index values are oriented around shady conditions and gentle breezes. Direct sunlight can cause a surge in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', quantifies the warmth felt when relative humidity is considered. This impact is subjective, influenced by the person's physical activity and individual heat perception, affected by factors including wind, attire, and metabolic differences. One's exposure to direct sunlight has the potential to intensify the heat sensation, increasing the heat index by up to 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical for babies and toddlers. Young kids are often more at risk than adults as they tend to perspire less. Besides, their skin surface is larger relative to their small bodies, and their increased heat output from their active lifestyle compounds their risk.
The human body keeps its cool primarily through perspiration, as this process enables sweat to evaporate, taking away the excess heat. A surge in relative humidity can disrupt the body's normal cooling function by slowing evaporation, hence reducing the rate at which the body cools and intensifying the perception of heat. Heat-related complications, like dehydration, can manifest if the body's heat gain exceeds its dissipation capacity.
