In Ston, Croatia, being aware of the UV Index is essential for safeguarding your health under the Mediterranean sun. Understanding UV levels not only helps prevent painful sunburn but also plays a crucial role in maintaining long-term skin health. With a Csa climate, Ston experiences significant UV exposure, particularly between 11:00 AM and 2:00 PM, when the UV Index peaks at 8—indicating a very high risk of harm from unprotected sun exposure. Staying informed about these levels empowers residents and visitors alike to enjoy the beautiful outdoors while taking necessary precautions.
As the sun rises, the UV Index steadily climbs, starting at a gentle 1 at 07:00. By 08:00, it nudges up to 2, and as the day progresses, the intensity escalates, peaking at a vibrant 8 between 12:00 and 14:00. This peak period, where the UV exposure is at its highest, calls for extra precautions and protection. As afternoon gives way to evening, the index begins to decline, falling back to 6 at 15:00 and gracefully tapering off to 1 by 19:00. Keep an eye on the UV Index today, stay safe in the sun, and enjoy the beautiful daylight!

As the seasons change, so do the UV index levels, which can significantly affect sun exposure for visitors and residents. January and December show low UV levels (Index 2), allowing for 45 minutes of safe exposure. However, as spring progresses, March and April enter the high category (Index 6-7), reducing safe burn time to 25 minutes. The summer months of May through August are particularly risky, with very high UV levels (Index 8-9) and a burn time dropping to just 15 minutes. As autumn approaches, September's UV index decreases to high (Index 7), allowing for 25 minutes of exposure, followed by moderate levels in October and November (Index 3-4), where safe burn times extend to 30 minutes. Residents and visitors are advised to monitor the UV index closely, especially between May and August, and take appropriate sun protection measures, including wearing sunscreen, hats, and protective clothing during high-risk months.
