Understanding the UV Index is crucial for residents and visitors in Srono, Indonesia, where the tropical climate contributes to elevated levels of ultraviolet radiation. Being aware of UV levels not only aids in preventing sunburn but is also vital for maintaining long-term skin health. Throughout the day, Srono experiences a considerable range of UV exposure, peaking at 10 during midday hours—putting those outdoors at risk of harmful effects. As a vibrant region within the Aw climate zone, Srono demands that locals and travelers alike stay informed about UV Index values to safeguard their skin against the sun's intense rays.
The UV Index today showcases a dynamic range, starting off mild at 7:00 AM with a value of 2. As the day progresses, the sun rises higher, peaking at 11:00 AM and 12:00 PM with a maximum index of 10, indicating very high levels of UV radiation. This midday surge makes 9:00 AM and 10:00 AM critical hours to protect your skin, reaching 7 and 9, respectively. Post-noon, the index gradually declines, dropping to 5 by 2:00 PM, before tapering off to 1 by 4:00 PM and returning to 0 after 6:00 PM.
