Upon reaching
May, unexpected rain showers are quite prevalent in
Rajshahi,
Bangladesh, with rainfall hitting a remarkable 129mm (5.08"). The rise in temperature is offset by the increase in humidity and surge in rainfall, making the weather relatively comfortable. It's advised to carry an umbrella at all times due to the unpredictable downpours, regardless of the scheduled sunshine hours. While the UV index remains high, the frequent rainfall significantly mitigates the heat of the afternoon sun.
Temperature
The initiation of May in Rajshahi sees an average high-temperature of a tropical 34.8°C (94.6°F), showing minor variations from the previous month. May nights are marked by an average temperature drop to a warm 23.5°C (74.3°F).
Heat index
May's average heat index is estimated at a scorching 41°C (105.8°F). Exercise more precautions, heat cramps and heat exhaustion are potential risks. Continuous activity could precipitate heatstroke.
Be aware that heat index ratings are designed for shaded locations and minor breezes. A rise of up to 15 Fahrenheit (8 Celsius) degrees in the heat index could result from direct sunlight.
Note: The heat index, also known as 'feels like' or 'apparent temperature', comes about by integrating the temperature readings with the humidity levels. An individual's perception of weather can be swayed by a variety of elements including metabolic differences, pregnancy status, and their level of physical exertion. Keep it in mind, direct sunlight can augment the heat you experience, possibly pushing the heat index up by 15 Fahrenheit (8 Celsius) degrees. Heat index values are highly critical to babies and toddlers. Kids often lack the knowledge about the necessity to take breaks and consume liquids. Thirst, as a late symptom of dehydration, necessitates the maintenance of hydration, particularly during enduring physical activities.
Perspiring is the body's way of cooling down, particularly by allowing sweat to evaporate and take the heat with it. In the presence of elevated relative humidity, the evaporation rate decreases. This reduction leads to increased body heat retention compared to conditions of dry air. When body temperature rises due to an imbalance in heat gain, there's a potential for dehydration and overheating.

Note: The daily high UV index of 12 during May translates into the following recommendations:
Implement every essential safety step. Individuals with fair skin might receive burns in less than 5 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. For a sun-safe wardrobe, go for clothes that are tightly woven and generously sized. A sunscreen boasting a minimum SPF of 30 should be generously applied and reapplied even on cloudy days, post swim or outdoor exercise.
