Understanding the UV Index in Nalchiti, Bangladesh is crucial for safeguarding your skin and overall health. With the region's Aw climate characterized by high temperatures and significant sun exposure, being aware of UV levels can help prevent painful sunburns and long-term skin damage. During the day, particularly between 10 AM and 2 PM, the UV Index can soar to a maximum of 13, indicating a very high risk of harm from unprotected sun exposure. By staying informed and taking necessary precautions, residents and visitors alike can enjoy the sunny days while keeping their skin safe and healthy.
The UV Index today offers a dynamic spectrum of sun intensity throughout the day. Starting off mild at 7:00 AM with a value of 2, the index climbs steadily as the sun ascends, peaking at a striking 13 between 11:00 AM and 12:00 PM. During these hours, it’s crucial to seek shade or apply sunscreen to protect your skin. The intensity then wanes from the early afternoon, dropping to 6 by 3:00 PM, and gradually dissipating to a calm 1 by 5:00 PM, where it hangs until sunset. Clearly, planning outdoor activities around the midday peak can help you enjoy the sunshine while staying safe!
