Understanding the UV Index is crucial for residents of Rangpur, Bangladesh, where the subtropical climate brings considerable sun exposure. Being aware of the UV levels helps prevent sunburn and protects skin health, allowing you to enjoy outdoor activities while minimizing risks. During the hottest parts of the day, particularly between 10 AM and 2 PM, UV levels can soar to an intense 12, indicating extreme risk of harm from unprotected sun exposure. With Rangpur's climate marked by hot summers and significant UV radiation, staying informed about UV index levels is essential for safeguarding your skin and overall health.
The UV Index presents a striking profile throughout the day, peaking dramatically from 11:00 AM to 12:00 PM with a maximum value of 12, indicating an intense level of solar radiation. Early risers will notice a more moderate ascent as the index starts at 2 at 07:00 AM, gradually climbing to 3 by 08:00 AM. The real intensity begins at 09:00 AM, surging to 6 before reaching a zenith of 11 by 11:00 AM. As the sun begins to dip post-noon, the index recedes to 9 at 02:00 PM, then gently descends to 6 by 03:00 PM, and continues its downward trend to settle at 0 by 07:00 PM. This data emphasizes the importance of sun protection during the peak hours when ultraviolet radiation is most potent.
