Understanding UV levels, especially during peak hours when the index can reach as high as 13, helps residents and visitors alike to take proactive measures against sunburn and long-term skin damage. With Tona's Cfb climate offering a mix of cooler and warmer days, it's important to recognize that even on seemingly mild days, UV exposure can pose significant risks, urging everyone to stay informed and safe under the sun.

The UV Index exhibits extreme levels throughout the year, with notable peaks occurring from March to April, where it reaches 15 to 16 and maintains a high level into early May. Visitors and residents should be particularly vigilant during February and March, when the index rises to 14 and 15, making these some of the highest-risk months for sun exposure, with a dangerously short burn time of just 10 minutes year-round. As such, it is crucial to adopt proactive sun protection measures, including using sunscreen, wearing protective clothing, and seeking shade, especially in midday hours. Even during the months of October and November, when the index decreases to 13 and 12, respectively, the risk remains significant, urging continued caution to prevent sun damage.
