Understanding the UV Index is crucial for residents and visitors in Larisa, Greece, where the sunny Mediterranean climate brings beautiful days but also significant sun exposure risks. With UV levels peaking at a high of 10 around midday, awareness of these fluctuations is essential for sunburn prevention and maintaining long-term skin health. By keeping an eye on the UV Index, you can take proactive measures to protect yourself from harmful rays, ensuring you enjoy the vibrant Larisa summers while minimizing the risk of skin-related issues.
The UV Index throughout the day presents a clear narrative of rising intensity, peaking in the afternoon. Starting at 1 by 07:00, the UV levels gradually ascend, reaching 5 by 10:00.

As the seasons change, so too does the UV Index, which is crucial for understanding sun exposure risks. From January to February, the UV Index remains moderate at 3 to 4, allowing for about 30 minutes of sun exposure without significant risk of burning. However, as March approaches, the index climbs to 6, indicating a shift to high risk with a reduced burn time of 25 minutes. The period from April to September marks the high-risk months for sun exposure, peaking at 11 in June, where only 10 minutes of unprotected exposure is safe. July and August maintain a 10 with a burn time of 15 minutes. By October, the index drops to 6, signaling a gradual decrease in risk, which continues through the winter months of November and December with indices reverting back to moderate levels at 4 and 3 respectively. Visitors and residents should be particularly cautious during the high UV months, practicing sun safety by using sunscreen, wearing protective clothing, and seeking shade during peak hours to mitigate potential harm from increased UV radiation.
