When it comes to rainfall in
Rajshahi,
Bangladesh,
July tops the charts with an imposing 301mm (11.85"). The relentless showers and high humidity often result in heavy cloud cover, further reducing the average sunshine hours. As the monsoon season peaks, the UV index hits the annual low, making it safe to be outdoors without worry of sunburns. Despite the harsh conditions, residents and visitors alike revel in the beauty of the monsoon and the rich, green landscapes it brings.
Temperature
The advent of July reveals an average high-temperature of a still hot 32°C (89.6°F), showing minimal difference from the prior month. Rajshahi's nights in July cool down to an average low-temperature of 25.9°C (78.6°F).
Heat index
July's mean heat index is estimated at a life-threatening hot 48°C (118.4°F).
Eyes open: Heat cramps and heat exhaustion are expected. Prolonged exertion could lead to heatstroke.
Bear in mind that the heat index values are determined for shaded areas and light breezes. Exposure to unobstructed sunshine could lead to an increase in the heat index by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'apparent temperature', provides an understanding of perceived warmth by combining temperature and relative humidity. The influence of weather is personal, with varied individuals experiencing it differently due to differences in body mass, stature, and physical exertion levels. When you're directly under the sun's rays, remember that the heat index may surge by 15 Fahrenheit (8 Celsius) degrees. Heat index values hold particular significance for children. Young children are more at risk than adults since they tend to sweat less. Moreover, their large skin surface in proportion to their small bodies and the high heat production due to their activities contribute to their vulnerability.
In the face of high temperatures, the human body's reflex is to perspire, leveraging sweat evaporation for cooling. Relative humidity in excess curtails evaporation, therefore reducing heat dissipation from the body, leading to feelings of excess heat. Overheating risks increase with rising body temperatures, especially if heat release isn't efficient.

Take every vital safeguard, as unprotected skin and eyes may suffer burns rapidly. Stay in the shade and avoid direct Sun exposure from 10 a.m. to 4 p.m., a period when UV radiation is particularly strong, noting that parasols or canopies may not offer total sun protection. Loose clothes with a tight weave are optimal for safeguarding yourself against the Sun's rays. Broad-spectrum sunscreen with an SPF of 30 or more should be applied liberally every two hours and directly after outdoor activities or swimming.
