June marks the arrival of the monsoon season in
Rajshahi,
Bangladesh, with rainfall reaching a formidable 272mm (10.71"). A steady increase in humidity accompanies the rain, contributing to the temperature remaining consistent. Alongside a decrease in the number of sunshine hours, the UV index decreases, reducing the possibility of sunburns. While the climate may seem inhospitable to some, the locals welcome the seasonal respite from the heat and the nourishment it provides to the agro-based economy.
Temperature
June is marked by an average high-temperature of a still tropical 33.3°C (91.9°F), almost identical to the preceding month. In June, the temperature drops to an average of 25.5°C (77.9°F) at night.
Heat index
The heat index value for June is estimated at a life-threatening hot 49°C (120.2°F).
Attention: Heat exhaustion and heat cramps are anticipated. Prolonged effort can result in heatstroke.
Heat index readings emphasize conditions of light breezes and shaded spots. Direct sunlight exposure may cause a 15 Fahrenheit (8 Celsius) degrees rise in the heat index.
Note: The heat index, also known as 'feels like' or 'real feel', provides an understanding of perceived warmth by combining temperature and relative humidity. The impact of weather is personal, differing among a variety of people based on differences in body mass, height, and the level of physical exertion. One must note that being under the direct sun can escalate the heat's effects, with the heat index possibly rising by 15 Fahrenheit (8 Celsius) degrees. Heat index values are particularly meaningful for babies and toddlers. 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 combat high temperatures, the human body perspires and relies on sweat evaporation for cooling. 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. If the body retains more heat than it can expel, the increasing temperature can lead to heat-related conditions.
Humidity
In June, the average relative humidity is 79%.

Enforce every vital precaution. Those with light skin could endure burns in a matter of minutes. Limit your exposure to the sun's UV radiation, which is strongest between 10 a.m. and 4 p.m., and note that parasols or canopies may not provide full sun protection. To cut down UV radiation exposure by about half, sport a wide-brim hat. One must apply and reapply generously an SPF 30+ broad-spectrum sunscreen every two hours or after an outdoor workout or swim.
