In Raciborz, Poland, being aware of the UV Index is crucial for maintaining skin health and preventing sunburn, especially during the sunnier months. Understanding UV levels not only helps residents protect themselves from harmful radiation but also encourages safer outdoor activities. With a Cfb climate that brings a mix of mild summers and overcast skies, Raciborz can sometimes mask the intensity of UV exposure, making it easy to underestimate the sun's effects. During peak hours, particularly between 11:00 AM and 1:00 PM, the UV Index can reach levels as high as 8, signaling a need for careful sun protection.
As the day unfolds, the UV Index rises steadily, peaking at 8 during midday hours, specifically at noon and 1 PM. This indicates a higher risk of harm from unprotected sun exposure, making it essential to take precautions during these hours. Starting the morning with a mild 1 at 7 AM, the UV Index climbs to 2 by 8 AM, gradually intensifying as it reaches 4 at 9 AM, and 6 at 10 AM. The intensity continues to soar as we approach noon, with 7 at 11 AM, before hitting that critical 8. As the afternoon progresses, there’s a gradual decline, with levels decreasing to 7 at 2 PM, then to 6 at 3 PM, and finally dipping to 3 by 5 PM. By evening, the UV Index settles back down to 2 at 6 PM and ultimately returns to a safe 1 by 7 PM, signaling a day of fluctuating sun exposure risks, highlighting the importance of sun safety throughout the hours.

Throughout the year, the UV Index exhibits significant seasonal variations, with peak levels typically occurring during the summer months. January and February have low UV ratings (Index 2), allowing for relatively prolonged exposure without risk of burning (45 minutes). As spring approaches, March (Index 4) and April (Index 5) see a shift to moderate levels, reducing safe exposure times to 30 minutes. The high-risk months are May through August, where the UV Index reaches its highest points—7 to 8—requiring caution with burn times of just 15-25 minutes. September remains a high-risk month (Index 6) before it tapers back to moderate values in October (Index 4). By November and December, UV exposure risks reduce significantly. Residents and visitors are advised to stay vigilant during peak UV months, wearing protective clothing and sunscreen, especially between late spring and summer, to safeguard against skin damage.
