Understanding the UV Index is crucial for the residents of Sunam, India, where the climate often presents significant exposure risks. Knowledge of UV levels can play a key role in preventing sunburn and maintaining overall skin health, especially during peak sunlight hours. With the Cwa climate, characterized by hot summers and varied seasonal patterns, it's essential to stay informed about daily UV fluctuations. For instance, during the late morning and early afternoon, UV levels can soar to 11—a reminder that protective measures are critical to safeguard against potential sun damage. Embrace awareness and enjoy the sun safely!
As the sun rises, the UV Index starts off low at 2 by 7:00 AM, gradually climbing to 3 by 8:00 AM. The intensity peaks dramatically by 12:00 PM, reaching an impressive 11, signaling the height of midday sun. For the next hour, the index remains robust at 10, but begins to taper off thereafter. The numbers drop to 8 at 2:00 PM, then decline further to 5 by 3:00 PM. As the day transitions toward evening, the UV levels fall to 3 at 4:00 PM, then gently descend to 1 by 5:00 PM, finally tapering off to 0 by 7:00 PM. This data highlights the importance of sun safety during the peak hours between 10:00 AM and 2:00 PM, when protective measures are crucial!

The UV Index exhibits significant seasonal variations, with the highest levels occurring from May to August. During this period, the UV Index reaches extremes of 10 to 11, indicating a very high to extreme exposure category, which corresponds to a burn time of just 10 to 15 minutes. Notably, July and August are the peak months for UV exposure, making sun safety a priority. From March to April, the UV levels remain very high, with a burn time of 15 minutes, suggesting that increased caution is still necessary. In contrast, the UV Index drops to moderate levels in January, November, and December, allowing for longer exposure times of 30 minutes without significant risk. Residents and visitors are strongly advised to take protective measures, such as wearing sunscreen, hats, and protective clothing, especially during high-risk months from March to September.
